The setting target of procedure PID is a relative
one, 100% of the setting equals to 100% of the
response of the controlled system.
The system is calculated according to the relative
value (0–100.0%).
Note:
Set multi-step speed, which can be compeleted
by setting P10 group parameters.
For PROFIBUS, Ethernet, and CANopen
communication setting, corresponding extension
cards are needed.
P09.01
Keypad PID
preset
When P09.00=0, set the parameter whose basic
value is the response value of the system.
Setting range: -100.0%–100.0%

Note: The reference and feedback channel
cannot coincide, otherwise, PID cannot control
effectively.

P09.03
PID output
feature
0: PID output is positive: when the feedback
signal exceeds the PID given value, the output
frequency of the VFD will decrease to balance the
PID. For example, the strain PID control during
wrapup
1: PID output is negative: When the feedback
signal is stronger than the PID given value, the
output frequency of the VFD will increase to
balance the PID. For example, the strain PID
0
