DETAILED PARAMETER DESCRIPTION
Figure 6.26 - Application example of an inverter with PID regulator
NOTE!
The inverter setting must be correct in order to obtain a good performance
of the PID regualtor. Ensure the following settings:
torque boosts (P136 and P137) and slip compensation (P138) in the
V/F control (P202=0 ou 1);
ensure that the self-tuning has been run, if in vector control (P202=2);
acceleration and deceleration ramps (P100...P103);
current limitation (P169).
