I need to issue position setpoint commands to a servo drive 50 times/sec. The drive will be responsible for closing the PID loop, etc, while the motion controller I'm developing will handle generating the setpoints to follow a custom trajectory.
I have the option of using Modbus TCP to communicate with the drive but worry that latency issues may arise when sending setpoints so frequently. Is Modbus suitable for such an application or should I consider another protocol such as CANopen? Or do I need to rethink my approach all together?
