Sec
Parameter sets the delay in which the integrator is reset after PID feedback value reaches PID setpoint value.
Example:
10-15 is set to 5 seconds. When the PID feedback value reaches the PID setpoint value, the drive will wait 5 seconds
before resetting the PID integrator.

The PID control function provides closed-loop system control. In case PID feedback is lost, the AC Drive output
frequency may be increased to the maximum output frequency. It is recommended to enable PID feedback loss when
the PID function is used.

: Disabled
10-11=1
: 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 "Pb" will be displayed on the keypad and the AC Drive 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 "Pb" will be displayed on the keypad, the AC Drive stops and the fault contact is activated.

Parameter 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 AC Drive response.
