aaqqxx Posted March 27 Share Posted March 27 (edited) I want to write a PLC or someting to do this. Take the PLC for example,when the PLC run:the acc of motor2 will be -0.5 times of the acc of motor 1, and when acc of motor 1 is 0 (and vel is 0), the motor 2 may move slowly to a good positon for next acc follow. How to do this? Badly for your help! Edited March 27 by aaqqxx Quote Link to comment Share on other sites More sharing options...
Gregs Posted March 30 Share Posted March 30 How will motors 1 and 2 be commanded to move? Jog moves issued from the PLC? Motion program moves, and if so, what mode, e.g. linear? Either way, I think that cascaded loop might work for this, with motor 1 on the inner and motor 2 on the outer loop, integrated so as to be a velocity correction to motor 1. See in the Power PMAC Users manual under the heading Cascading Servo Loops. Motor 2 would be commanded to move as desired when motor 1 is at 0 velocity.
