Description
and lower limits of PID regulator output values.
100.0% corresponds to the max. output
frequency (P00.03) or max. voltage (P04.31).
P09.09 setting range: P09.10––100.0%
P09.10 setting range: -100.0%–P09.09
Used to set the PID feedback offline detection
value. When the feedback value is smaller than
or equal to the feedback offline detection value,
and the duration exceeds the value specified by
P09.12, the VFD reports "PID feedback offline
fault" and the keypad displays PIDE.

Ones place:
0: Continue integral control after the frequency
reaches upper/lower limit
1: Stop integral control after the frequency
reaches upper/lower limit
Tens place:
0: Same as the main reference direction
1: Contrary to the main reference direction
Hundreds place:
0: Limit as per the max. frequency
1: Limit as per A frequency
Thousands place:
0: A+B frequency. ACC/DEC of main reference A
frequency source buffering is invalid.
1: A+B frequency. ACC/DEC of main reference A
frequency source buffering is valid. The
ACC/DEC is determined by P08.04 (ACC time 4).
