The MDC300-120301 driver is designed to drive DC brushless motors at currents of up to 30.0A and 170VDC. A constant velocity mode can be selected, using hall sensor feedback. The driver is protected against under voltage, hall sensor current, and over current (cycle-by-cycle or latched). 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 are internal potentiometers to control the maximum phase current, and the speed of the motor. An external voltage may be used to control speed as well.
