Hi, I have a PLC Fx5U.
The PLC controls the stepper motor with the crankshaft mechanism.
Therefore, the dependence of the position of the pusher on the angle of rotation is not linear.
I need to get linear movement of the pusher.
To control stepper motors I use the DRVI function.
In this function I can set a stable speed, but I need to change the speed as the crank moves. The crank movement time is 0.2-0.3 seconds. 1 turn.
How can this problem be solved?
