MDC300-240081

The MDC300-240081 driver is designed to drive DC brushless motors at currents of up to 7.5A peak and 340VDC. Using hall sensor feedback, a constant velocity mode can be selected. The driver is protected against over current (cycle-by-cycle or latched), hall sensor error and under voltage. When an error occurs, a fault light notifies the user. If the fault latch is enabled and an error occurs, the fault output goes low to notify the user. Included on the driver is an internal potentiometer to control the maximum phase current allowed into the motor and an internal potentiometer to control the speed of the motor. An optional external potentiometer or voltage input can be used to control the speed as well. The direction of the motor can be preset by the direction control input or controlled by the external voltage speed input. Other inputs to the drive include a run/stop and a motor freewheel input. An onboard potentiometer sets the ramp up/down profile from standstill. The run/stop input overrides all other inputs into the driver.
