Frequency Inverter ST600 Series High-Performance Multifunction VFD Function parameter list
-181-
P09––PID control
When frequency command (P00.06, P00.07) is set to 7,
or channel of voltage setup (P04.27) is set to 6, the
VFD running mode is process PID control.
This parameter determines the target reference channel
of process PID.
0: Set by P09.01

The set target value of process PID is relative value, the
set 100% corresponds to 100% of the feedback signal
of controlled system.
The system operates based on the relative value (0–
100.0%)
Users need to set this parameter when P09.00 is set to
0, the reference value of this parameter is the feedback
variable of the system.
Setting range: -100.0%–100.0%
This parameter is used to select PID feedback channel.

Note: The reference channel and feedback channel
cannot overlap; otherwise PID cannot be controlled
effectively.
0: PID output is positive characteristic: namely, the
