10-10: Low pass filter situated before the PID limit block that can be used to prevent PID output resonance.
Increase the time constant to a value greater than the resonance frequency cycle and reduce time constant to
increase the inverter response.

Warning
A feedback loss condition is detected when the PID feedback value falls below the value set in parameter 10-12
(PID feedback loss detection level) for the time set in parameter 10-13 (PID feedback loss detection time). PID
feedback loss warning message "PDER" will be displayed on the keypad and the inverter will continue to operate.
10-11=2:
Fault
A feedback loss condition is detected when the PID feedback value falls below the value set in parameter 10-12
(PID feedback loss detection level) for the time set in parameter 10-13 (PID feedback loss detection time). PID
feedback loss fault message "PDER" will be displayed on the keypad, the inverter stops and the fault contact is
activated.

10-14: PID integral limit:
Used to limit the integral output to prevent motor stall or damage to the system in case
of a rapid change in the feedback signal. Reduce the value of 10-14 to increase the inverter response.
