PID Offset Adjustment (n133)
Constant
No.
n133
Constant n133 adjusts the PID control offset.
If both the target value and the feedback values are zero, adjust n133 so
that the Inverter output frequency is zero.
Primary Delay Time Constant for PID Output (n135)
Constant
No.
n135
Constant n135 is the low-pass filter setting for PID control outputs.
There is normally no need to change the setting.
If the viscous friction of the mechanical system is high or if the rigidity
is low causing the mechanical system to resonate, increase the setting so
that it is higher than the resonance frequency period.
PID Output Gain (n163)
Constant
No.
n163
Constant n163 adjusts the output gain.
PID Feedback Gain (n129)
Constant
No.
n129
Constant n129 is the gain that adjusts the feedback value.
