I'm using RS-232 in open loop mode. We have a PID loop running at 20ms that calculates the output to the roboteq.<BR><BR>There is a delay of 60 msec between when we send the command, and when the motors respond. The encoder response and motor output ('?V') both show response after 60 msec. <BR><BR>Our encoders provide feedback at 10ms, so this delay is beyond what I expected based on the loop timings and sample delays.<BR><BR>The 60 msec delay is in place whether I look at a step up response or a step down response.<BR><BR>Is there anyway to speed the response up? (I've tried removing deadband and increasing the acceleration.)<BR><BR>
