RDM Series Joint Servo Drivers for Collaborative Robots

RDM cooperative robot joint servo drive module is a high performance, DC power supply, extremely compact digital universal servo driver based on advanced FPGA technology. The maximum power can reach 1000W. The position, speed and torque of servo motor are controlled by EtherCAT/CANopen bus, which greatly reduces the cost of each node in EtherCAT/CANopen bus multi-axis system.

As an EtherCAT/CANopen slave station, the RDM driver module runs with the CoE protocol of DSP-402, and supports position/speed/torque cycle synchronization, position/speed/torque curve, PVT and back-to-origin mode.

Through RS232 or EtherCAT communication interface and PC software, system parameters can be programmed to adjust, firmware upgrade, and configuration parameters can be saved or read.
