CHAPTER 6 - DETAILED PARAMETER DESCRIPTION
2) Automatic Operation: open the DI and make the dynamic setting of
the PID regulator, i.e., set the proportional gain (P520), integral
gain (P521) and differential gain (P522).
NOTE!
The inverter setting must be correct in order to obtain a good
performance of the PID regulator. Ensure the following settings:
Torque boosts (P136 and P137) and slip compensation (P138) in
the V/F mode control (P202 = 0 or 1);
Acceleration and deceleration ramps (P100 to P103);
Current limitation (P169).
