Note:
1. Set multi-step speed, which can be
compeleted by setting P10 group parameters.
2. For PROFIBUS, Ethernet, and CANopen
communication setting, corresponding extension
cards are needed.

The function code is mandatory when P09.00=0.
The base value of the function code is the
feedback of the system.

Note: The reference channel and feedback
channel cannot be duplicate. Otherwise,
effective PID control cannot be achieved.

PID output
characteristi
cs
0: PID output is positive. When the feedback
signal is greater than the PID reference value,
the output frequency of the VFD will decrease to
balance the PID. Example: PID control on strain
during unwinding.
1: PID output is negative. When the feedback
signal is greater than the PID reference value,
the output frequency of the VFD will increase to
balance the PID. Example: PID control on strain
during unwinding.

proportional
gain (Kp)
The function is applied to the proportional gain P
of PID input.
P determines the strength of the whole PID
adjuster. The value 100 indicates that when the
difference between the PID feedback value and
given value is 100%, the range within which the
