Frequently Asked Questions
What is the difference between an AC Servo and a DC Servo?
A DC servo motor uses a DC Brush motor and PWM control circuitry to vary the current through a single phase. An AC servo motor uses a BLDC motor and controls the motor through sinusoidal currents of three phases. DC servo motors contain brushes and are thus prone to maintenance every 2000 hours of operation where the AC servo motor are brushless motors and thus do not have the maintenance issues. DC servo motors though do not have complex control circuitry required that the three phase AC servo motors need.

Are Anaheim Automation servo motors AC or DC?

What AA products can work with the Programmable Logic Controller (PLC)?
Anaheim Automation's Programmable Logic Controllers (PLCs) can work with encoders for position control, or they can be connected to a PCL601, 17MDSI or any controller that takes ASCII commands via an RS232 or RS485 port. The Human Machine Interface (HMI's) can also communicate with our servo drives because of their RS232 port which processes MODBUS ASCII protocol.

Can you use an HMI with a Servo System?
Yes. Any HMI that can send out strings of ASCII text can be used to control the EDC and ProNet-E Servo Drives and Controllers.

What precautions should I take in setting up my servo motor and drive system?
Install servo motors, drivers and controllers, as well as other electronic and mechanical components, in an environment which is free from electrical noise, vibration and shock. Additionally, it is preferable to work with these products in a non-static, protective environment. Please refer to the details discussion of EMI in the installation section of our web site. Exposed circuitry should always be properly guarded and/or enclosed to prevent unauthorized human contact with live circuitry. IMPORTANT NOTE: No work should be performed while power is applied. DO NOT plug in or unplug any connectors when power is ON. Wait for at least 5 minutes before doing inspection work on the motion control 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 drivers and controllers. Read the user's guides that are available on our web site for each product purchased. Do not operate a motion control system in the presence of flammable gases, dust, debris, oil, vapor or moisture/condensation. For outdoor use, servo motors, drivers and controllers, and other electronic and mechanical components 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, moisture and vapors of any kind. Contact the factory should your application require specific IP ratings.

How do I restore the EDC Servo Drive parameters back to factory default value?
Upon initial startup, the EDC Servo Drives and Controllers should contain factory settings. Should the user wish to default back to the factory settings, follow the steps below:

1. Press the MODE Key to select Auxiliary Function Mode.
2. Press the INC or DEC Key to select the function number for restoring defaults (Fn001).
3. Press the ENTER Key to enter the parameter restoring mode.
4. Press and hold the ENTER Key for a second to restore ALL the parameter to their default values.
5. Release the ENTER Key to return to the function number display.

After following the steps above, ALL the parameters should be returned to their factory default value. A list of these values can be found in the EDC User’s Manual.

What are the advantages and disadvantages of a digital servo drive?
Some of the advantages of a digital servo drives are instantaneous response, programmability and torque. Digital servos implement a microprocessor which is faster than an analog servo. This quicker microprocessor allows the servo to obtain a quicker response to variable changes such as speed and positioning. Anaheim Automation’s servo drives can be programmed to control the direction the servo motor rotates, end point positioning, speed, and torque. The disadvantage of a digital servo drive is power consumption. In obtaining a faster response time and high standing torque, digital Servo Drives and Controllers require more power consumption than other servo drives.

Can I use 220VAC Single Phase power input on my servo system?
Yes, you can use 220VAC single phase input power depending on the model purchased for your servo system. All EDC Servo Systems accept 220VAC single phase input power while only the ProNet-E-02/04/08/10/15 can use either 220VAC single phase or three phase power input. ProNet-E-20/30/50 only accept three phase input.

Can I use an HMI with a Servo System?
Yes. Any HMI that can send out strings of ASCII text can be used to control the EDC or the ProNet-E Servo Systems.

What is a servo motor?
A servo motor is a motor which is part of a servomechanism which can be a DC, AC, or Brushless AC/DC motor. It is typically paired with some type of encoder to provide positioning and speed feedback. Servo motors use error-correction routines to correct its position. The term servo can be applied to systems other than servo motor; systems that use a feedback mechanism such as an encoder or other feedback device to control motion parameters.

What is the winding configuration for the EMJ, EMG, EML, and EMB Servo Motors from ESTUN?
The EMJ, EMG, and the EML Servo Motors are in a Star Wound Configuration. These motors are also PMSM (Permanent Magnet Synchronous Motors) and they are controlled through sinusoidal waveforms.

What does an error code "write absolute error 03" mean on my servo drive?
The error code "write absolute error 03" indicates that a parameter is beyond a maximum value or below a minimum value. Please check the parameters to ensure this criteria is met and try reloading the program to your servo drives.
