MD20#
MD20 is a mall brushless motor controller. It is best suited to small and precise gimbaling motors. The controller features position PID, velocity PID, impedance, raw torque, profile position and profile velocity operation modes. MD20 can be easily daisy-chained, for easy connection of many drives in a single control network.

Connectors pinout#
For power supply and CAN bus connection two 2200980471 Molex Micro-lock connectors are available. They act as an internal bridge for easy chaining of the drives.
For external encoder connection via the SPI 530480650 Molex PicoBlade connectors is provided.
For external encoder connection via the RS422 and the GPIO pins utilization 530480810 Molex PicoBlade connectors could be used.
