default value
0.0s
F6-02
Setup range 0.0s to 3000.0s
PID reference changes according to this parameter value, which
corresponds to the time taken for the PID reference to change from 0% to
100%.

value
1 Negative action
Positive action: If the feedback signal is smaller than the PID reference
signal, it is required to boost the output frequency of the inverter to make
PID reach balance. The winding tension PID control is such a case.
Negative action: If the feedback signal is smaller than the PID reference
signal, it is required to decrease the output frequency of the inverter to
make PID reach balance.
The unwind tension PID control is such a case.

Setup range 0 to 65535
PID reference feedback range is a dimensionless unit which is only used to
the value that displays PID reference and feedback currently.
For example, if the parameter is set as 1000, the range 0%- 100% for PID
reference and feedback is linear correspondence with 0-1000.
