For details contact Anaheim Automation directly.

Flexibility is the Key to Successful Automation
Despite the familiarity Anaheim Automation, Inc. has with helping in the design of automating equipment in todays world, there is often an instance where automated controls are not used to perform a designated task without the presence of human judgment. Consequently, this type of procedure can limit the amount of alternative methods of production, and be labor intensive. This was present in the case of the oil drilling lathe project that came to us. A large lathe was used to thread drill pipe for oil well drilling operations. A drill pipes diameter varies, up to two feet in diameter. Therefore, it is essential to keep close thread tolerances to ensure even stress points during drilling. Anaheim Automation needed to coordinate the programming, the electronics, and other disciplines (i.e. hardware and software support), required for the development of this automated control system. Together with the customer - a machinery builder - we achieved an automated control system that incorporates the skill of the operator, into an automated performance using stepper drivers. This was a large endeavor; many features were built into the machine, including the depth of cut, number of passes, safety cutoff with automatic retract, and rapid traverse. Anaheim Automation succeeding in providing maximum performance in this application using high-performance step motors, stepper drivers, and stepper controllers. When completed, essentially all the customer needed to do was to press a button, and the lathe cut and finished one perfect thread. The machine was a success, due to its relatively easy operation. Unfortunately, this first lathe design was automated to the point where everyone that used it was forced to mold to its abilities; as result a new criteria was developed. The new lathe design provided customers with the ability to perform a complete threading operation without mediating the process, and still allowed them to have the luxury of customization found in manual machines. The customer can disable the automated process and utilize the machine completely manually, if desired. The system could even be installed on an already existing manual machine. Due to their ability to increase production speed, as well as the fact that they can be operated safely and easily, larger lathes can be found nationwide at drilling sites being operated by relatively inexperienced workers. In this application, Anaheim Automation found a way to maximize the performance of stepper drivers automated threading pipe by incorporating human judgment and control, while avoiding obsolescence among older technology.

Microstep Drivers Head Out to Sea
One of Anaheim Automations customers is known for a number of undersea products, including a variety of instruments and high-pressure cleaning equipment to keep submerged portions of oil platforms free of marine growth. Many of their technicians and engineers over the years, have collaborated and collected hundreds of years of experience in solving problems that deal with the undersea environment. Once technology advanced, the company focused on developing both custom and commercial lines of computer-controlled, free-swimming, unmanned, submarines for researching, exploration, and maintenance applications. For several of the models, precise motion control became necessary to operate them, and Anaheim Automation helped by supplying micro stepper drivers to them. Having a torpedo-like appearance, the AUVs (Autonomous Undersea Vehicle) typically had a 21 inch diameter, and were 15 feet long with a rounded nose and a tale equipped with a vertical rudder and a horizontal elevator. They could range over more than a 100-mile radius and can dive to 2,000 feet or more, depending on its purpose. They can cost anywhere from hundreds of thousands of dollars to several million. Typically, an AUV could be programmed to head north for 25 minutes and then brush back and forth over an area on the bottom as it traveled back to the launch area. Engineers had the idea to combine artificial intelligence with undersea technology to create vehicles that could follow instructions and act on their own. The artificial intelligence is necessary because it is difficult to accomplish high speed communication through water, so it allows the AUV to deal with unexpected obstacles such as strong currents, for example. AUVs are equipped with configurations such as side-scanning SONAR, LIDAR (a system similar to RADAR), and cameras, in order to aid in underwater explorations, mapping, and searches. However, fitting the AUVs with this equipment is not without tradeoffs. It takes a large portion of volume to power an AUV with on-board equipment; batteries take up much of the needed equipment space, thus power is allocated carefully. One way power is conserved is in the steering system. Even a small change in the rudder and elevator can significantly change the direction of the vessel. Any additional angle is considered over steering, and thus is a noteworthy waste of power. Step motors and stepper drivers actually help to control the fine alterations in the rudder and elevator. There is an on-board computer that controls the steering surfaces, and in times where steering is critical or power is at a premium, micro stepper drivers provided by Anaheim Automation are used. When batteries are charged, the power is 140 volts DC and 105 volts when the batteries are low. Anaheim Automation developed light-weight compact microstep drivers to operate within the range of 100-150-volt operation. The divide-by-ten stepper drivers use opto-isolated inputs to revive clock and direction signals from the computer. This information is then converted into the 5.5-amps-per-phase output required to operate the steering step motors at 2,000 steps per revolution. Currently, the firs AUV with microstep steering is undergoing multiple tests in the ocean, as do many AUV vessels. As the operators gain more confidence, more control is transferred to the on-board computer. Eventually, the AUV will be sent out on its own, without an operator to compute multifaceted sea assignments.

While every effort is made to offer solid advice regarding the stepper drivers product line, as well as other motion control products, and to produce technical data and illustrations accurately, such advice and documents are for reference only, and subject to change without notice.

Environmental Considerations
The following environmental and safety considerations must be observed during all phases of operation, service and repair of stepper drivers system. Failure to comply with these precautions violates safety standards of design, manufacture and intended use of the stepper drivers and motors. Please note that even a well-built stepper drivers products operated and installed improperly, can be hazardous. Precaution must be observed by the user with respect to the load and operating environment. The customer is ultimately responsible for the proper selection, installation, and operation of the stepper drivers and motors system. The atmosphere in which stepper drivers is used must be conducive to good general practices of electrical/electronic equipment. Do not operate the stepper drivers in the presence of flammable gases, dust, oil, vapor or moisture. For outdoor use, the stepper drivers and motors must be protected from the elements by an adequate cover, while still providing adequate air flow and cooling. Moisture may cause an electrical shock hazard and/or induce system breakdown. Due consideration should be given to the avoidance of liquids and vapors of any kind. Contact the factory should your application require specific IP ratings. It is wise to install the stepper drivers and motors in an environment which is free from condensation, electrical noise, vibration and shock. Additionally, it is preferable to work with the stepper drivers/motor /controller system in a non-static protective environment. Exposed circuitry should always be properly guarded and/or enclosed to prevent unauthorized human contact with live circuitry. No work should be performed while power is applied to the stepper drivers. Don’t plug in or unplug the connectors when power is ON. Wait for at least 5 minutes before doing inspection work on the stepper drivers and motors system after turning power OFF, because even after the power is turned off, there will still be some electrical energy remaining in the capacitors of the internal circuit of the stepper drivers. Plan the installation of the stepper drivers and motor in a system design that is free from debris, such as metal debris from cutting, drilling, tapping, and welding, or any other foreign material that could come in contact with circuitry. Failure to prevent debris from entering the stepper drivers/motor system can result in damage and/or shock.

How to Select Stepper Drivers
The amount, speed, and direction of rotation of a stepper motor are determined by the appropriate configurations of digital control devices. Selecting the most compatible stepper drivers, motors, and/or controllers, can save the user money and be a less cumbersome motion control solution. Anaheim Automation categorizes the major types of digital control devices as follows: • Stepper Drivers – offered in full-step, half-step and micro-step • Stepper Motor Controllers (sometimes referred to as Control Links – controllers indexers, and pulse generators sold separately or in drivers packs • Stepper Motor Driver Packs – packaged units that include drivers and optional controller, with a matched power supply (most models are enclosed units that are fan-cooled) • Integrated Stepper Drivers/Controllers – packaged at the end of a stepper motor are drivers and simple controllers (only available for high-torque stepper motors) Stepper drivers provide a method to precisely control speed and positioning. With each pulse converted into digital information, the motor is able to undergo an exact incremental rotation without the need for feedback mechanisms i.e. tachometers or encoders. With an open-loop system, the problems of feedback loop phase shift and resultant instability, common with servo drives, are eliminated. Before a designer selects a suitable stepper drivers and motor combination for an application, there are certain variables needed to be considered. A designer must examine several parameters such as load characteristics, performance requirements, and mechanical design including coupling techniques for an optimal solution for a stepper drivers and motor combination. Failure to do so may result in poor system performance or cost more than necessary. For optimum stepper drivers motion control, the following factors should be taken into consideration: 1. Parameters: a. Distance to be traversed b. Maximum time allowed for a traverse c. Desired detent (static) accuracy d. Desired dynamic accuracy (overshoot) e. Time allowed for dynamic accuracy to return to static accuracy specification (settling time) f. Required step resolution (combination of step size, gearing, and mechanical design) g. System friction: All mechanical systems exhibit some frictional force. When sizing the motor, remember that the most must provide enough torque to overcome any system friction. A small amount of friction is desired since it can reduce settling time and improve performance h. System inertia: An object’s inertia is a measure of its resistance to changes in velocity. The larger the inertial load, the longer it takes a motor to accelerate or decelerate the load. The speed at which the motor rotates is independent of inertia. For rotary motion, inertia is proportional to the mass of the object being moved times the square of its distance from the axis of rotation i. Speed/Torque characteristics of the motor: Torque is the rotational (in ounce-inches) defined as a linear force (ounces) multiplied by a radius (inches). When selecting a stepper drivers and motor, the capacity of the motor must exceed the overall requirements of the load. The torque any motor can provide varies with its speed. Individual speed/torque curves should be consulted by the designed for each application j. Torque-to-Inertia Ratio: This value is defined as a motor’s rated torque divided by the rotor’s inertia. This ration (measurement) determines how quickly a motor can accelerate and decelerate its own mass. Motors with similar torque ratings can have different torque-to-inertia ratios as a result of varying construction k. Torque margin: Whenever possible, stepper drivers which can provide more torque than is necessary should be specified. This torque margin allows for mechanical wear, lubricant hardening, and other unexpected friction. Resonance effects can cause the motor’s torque to be slightly lower at some speeds. Selecting stepper drivers and motors system that provides at least 50% margin above the minimum required torque is ideal. More than 100% may prove too costly 2. Calculation: Measurement of inertia, friction and workloads reflected to motor. a. In an open-loop stepper drivers system, the motor does not “know” if excessive inertia or friction has made the motor lose or gain one or more steps, thus affecting the position accuracy b. Load inertia should be restricted to no more than four times motor rotor inertia for high performance (relatively fast) systems. A low performance system can deliver step accuracy with very high inertia loads, sometimes up to ten times rotor inertia. System friction may enhance performance with high inertia loads Experimentation: Tailoring Experimentation for motor sizing is critical due to dynamic changes in system friction and inertia, (load anomalies) which are difficult to calculate. Motor resonance effects can also change when the motor is couple to its load

Mounting
The following information is intended as a general guideline for the installation and mounting of the stepper drivers and motors system. WARNING - Dangerous voltages capable of causing injury or death may be present in the stepper drivers and motor system. Use extreme caution when handling, testing, and adjusting during installation, set-up, and operation. It is very important that the wiring of the stepper drivers and motor be taken into consideration upon installation and mounting. Subpanels installed inside the enclosure for mounting stepper drivers, motor and system components, must be a flat, rigid surface that will be free from shock, vibration, moisture, oil, vapors, or dust. Remember that the stepper drivers and motor will produce heat during work, therefore, heat dissipation should be considered in designing the system layout. Size the enclosure so as not to exceed the maximum ambient temperature rating. It is recommended that the stepper drivers be mounted in position as to provide adequate airflow. The stepper drivers, as well as the motor, should be mounted in a stable fashion, secured tightly. NOTE: There should be a minimum of 10mm between the stepper drivers, motor, and any other devices mounted in the system/electric panel or cabinet. NOTE: In order to comply with UL and CE requirements, the stepper drivers and motor system must be grounded in a grounded conducive enclosure offering protection as defined in standard EN 60529 (IEC 529) to IP55 such that they are not accessible to the operator or unskilled person. As with any moving part in a system, the stepper motor should be kept out of the reach of the operator. A NEMA 4X enclosure exceeds those requirements providing protection to IP66. To improve the bond between the power rail and the subpanel, construct your subpanel out of a zinc-plated (paint-free) steel. Additionally, it is strongly recommended that the stepper drivers be protected against electrical noise interferences. Noise from signal wires can cause mechanical vibration and malfunctions.

How Should I Heatsink My Stepper D
There is not stepper drivers-specific heatsink for any Anaheim Automation stepper drivers; however there are numerous ways to heatsink stepper drivers (and any other type of driver or controller). IMPORTANT NOTE: Make certain your stepper drivers has adequate air flowing over it, and fins that increase the overall surface area. Anaheim Automation recommends using a standard CPU heatsink with a liberal amount of heatsink compound placed between the finned aluminum heatsink and the stepper base/mounting plate. Feeling the stepper drivers while it runs will help determine if it is being sufficiently cooled. If it is uncomfortable to touch the stepper drivers electronics, then most likely the electronics are being damaged as well.

Keep Clock and Motor Wires Sep
Clock pulse is the culprit for up to eighty percent of stepper drivers problems. The most common reason for clock problems is wire position. When clock wires are placed too close to motor wires, this causes extraneous voltages to arise within the clock wires. The tip to remember: Always physically separate your clock and motor wires. Better yet, purchase Anaheim Automation shielded motor cable along with your stepper drivers choice.

Mounting Options for BLD75 Drivers
Anaheim Automation has popular BLD75 series bi-level stepper drivers that contain on-board rectifiers and filter capacitors that were originally designed for operation in fan-cooled installations. However, because of the flexibility of the stepper drivers BLD75, customers wanted to use it in other types of installations. Model number BLD75 (with no dash) indicates the original stepper drivers that is sold as a replacement for a stepper drivers used in BLD75 series stepper Driver Packs. The sheet metal is smaller and thinner because they are intended to be reinstalled in stepper Driver Packs that are fan-cooled. Model number stepper motor driver BLD75-1 eliminates the need for fan-cooling because it employs a large and thick heat sinking base/mounting plate. The BLD75 -1 option allows the stepper drivers to be mounted vertically or horizontally. NOTE: A common mistake is that customers order a stepper motor driver BLD75-1 for a replacement in a bipolar step motor Driver Pack, only to find that it will not mount inside their bipolar step motor Driver Pack. When ordering, please tell the customer service representative what is the intended use of the stepper drivers, so that you receive the correct option for your application.

Labeling Services
Dont see exactly what you want in stepper drivers or controllers? Private-labeling may be your answer. Private-labeling is used for a variety of reasons in the business world. Some companies simply prefer to have a custom product with their own company name on the equipment they produce for recognition, while others utilize it to conceal sources from competition, or for uniformity among their products. Anaheim Automation has been accommodating requests for customization and private-labeling on their products for many decades now. Actually, for some large orders, we have even waived the setup and screening costs. One company that produces highly technical positioning products uses privately labeled bipolar step motor Driver Packs in its products because it increases their company recognition as a technology leader. Other companies similarly use Anaheim Automation stepper drivers labeled with their names and logos, along with custom programmed integrated circuits for the accompanying stepping motor controller. For additional information on private-labeling, contact the Anaheim Automation factory.

What are Stepper Drivers
Stepper drivers are a circuit able to generate the required current to drive the stepper motor. The main function of stepper drivers is to provide the rated motor phase current to the stepper motor windings in the shortest amount of time. The rate of change of current through the windings is crucial for the stepper motor to run at optimal speed and torque. The resistive force to current change is inductance. In order for current to flow faster, it must overcome the inductive force. The inductive time constant plays a vital role in the rate at which current will flow. A low inductive time constant constitutes a faster current flow rate, while a larger inductive time constant will reduce the current flow rate. Stepper drivers usually operate by chopping the input supply voltage. The stepper drivers do this by using an embedded pulse width modulation (PWM) chip. Three basic stepper drivers categories include L/R, Bilevel, and PWM.

Wiring
The following information is intended as a general guideline for wiring of the Anaheim Automation stepper drivers and motors product lines. Be aware that when you route power and signal wiring on a machine or system, radiated noise from the nearby relays, transformers, and other electronic devices can be induced into the stepper drivers and motors, and encoder signals, input/output communications, and other sensitive low voltage signals. This can cause systems faults and communication errors. WARNING - Dangerous voltages capable of causing injury or death, may be present in the stepper drivers motor system. Use extreme caution when handling, wiring, testing, and adjusting during installation, set-up and operation. Don’t make extreme adjustments or changes to the stepper drivers and motors system parameters, which can cause mechanical vibration and result in failure and/or loss. Once the stepper drivers and motors are wired, do not run the stepper drivers by switching On/Off the power supply directly. Frequent power On/Off switching will cause fast aging of the internal components, which will reduce the lifetime of stepper drivers system. Strictly comply with the following rules: • Follow the Wiring Diagram with each stepper motor and stepper drivers combination. NOTE: Manufacturers vary in their color code wiring schemes • Route high-voltage power cables separately from low-voltage power cables. • Segregate input power wiring and stepper drivers/motor power cables from control wiring and motor feedback cables as they leave the stepper drivers and motor. Maintain this separation throughout the wire run. • Use shielded cable for power wiring and provide a grounded 360 degree clamp termination to the enclosure wall. Allow room on the sub-panel for wire bends. • Make all cable routes as short as possible. NOTE: Factory made cables are recommended for use in our stepper drivers and motor systems. These cables are purchased separately, and are designed to minimize EMI. These cables are recommended over customer-built cables to optimize system performance and to provide additional safety for the stepper drivers/motor system and the user. WARNING - To avoid the possibility of electrical shock, perform all mounting and wiring of the stepper drivers system prior to applying power. Once power is applied, connection terminals may have voltage present.
