What I would do, I think, is run one motor as a master in closed-loop speed control, then slave the other motors to its encoder counts in closed-loop position control. The the "slave" motors will try to stay in exact phase with the master. You will have to write the HAL for this yourself, but it will look like a combination of 1x closed-loop speed control and 4x standard servo control, but with the position commands from the master encoder, not an EMC2 pin. -- atp The idea that there is no such thing as objective truth is, quite simply, wrong. ------------------------------------------------------------------------------ Write once.
