Note: When the run time exceeds the delay, the
VFD detects for output phase loss.
Description
When frequency command selection (P00.06,
P00. 07) is 7, or channel of voltage setup
(P04.27) is 6, the running mode of VFD is
process PID control.
The function code determines the target given
channel during the PID process.

The set target of process PID is a relative value,
for which 100% equals 100% of the feedback
signal of the controlled system.
The system always performs calculation by
using a relative value (0–100.0%).
The function code is mandatory when P09.00=0.
The base value of The function code is the
feedback of the system.
Setting range: -100.0%–100.0%
