Pid Regulator Tuning; Initial Settings Of Pid Regulator - CS-Lab SimDrive M4-H075K User Manual

5.6 PID controller tuning
For beginners it's the hardest stage of the
configuration but following the manual even they can
tune the PID controller properly and pretty fast.
Before we enter power output stage (HV) and we
switch a servo drive on („Servo ON") we should first
enter initial, low values of the controller to avoid loud
motor oscillation right after we turn the motor.
Open PID tuning window
„ConfigurationPID tuning" or click on the
on the toolbar.

5.6.1 Initial settings of PID regulator

Optimal, initial values for various motor types may differ significantly however in the table below
there are parameters which should be „safe" in most of cases – they shouldn't cause motor
oscillations after it is turned on.
