Same to PA-10~PA-12, the second set of PID parameters.
0: positive action 1: negative action
Positive action: when the feedback signal of PID is less than the given quantity, the output frequency of
frequency converter rises. Such as winding tension control occasions.
Negative action: when the feedback signal of PID is less than the given quantity, the output frequency of
inverter decreases. Such as unwinding tension control occasions.
The function is affected by the reverse action direction of the multi-function terminal PID, which needs
attention in use.
PID given feedback range is a dimensionless unit, used for PID given display U0-14 and PID feedback display
U0-15.
The relative value of the given feedback of PID is 100.0%, corresponding to the given feedback range PA-20.
For example, if PA-20 is set to 2000, when PID is given 100.0%, U0-14 is 2000.
PID maximum deviation between two

PID initial value holding time
When the VFD is started, PID output is fixed to PID initial value PA-23, and PID does not start closed-loop
adjustment operation until the initial value of PID is maintained for PA-24. The following figure shows the
