2.2 b: Application
b5-06: PID Output Limit
■
Sets the maximum output possible from the entire PID controller. Set as a percentage of the maximum frequency (E1-
04).
No.
b5-06
b5-07: PID Offset Adjustment
■
Sets the offset added to the PID controller output. Set as a percentage of the maximum frequency.
No.
b5-07
■ b5-08: PID Primary Delay Time Constant
Sets the time constant for the filter applied to the output of the PID controller. Normally, change is not required.
No.
b5-08
Note: Useful when there is a fair amount of oscillation or when rigidity is low. Set to a value larger than the cycle of the resonant
frequency. Increasing this time constant may reduce the responsiveness of the drive.
b5-09: PID Output Level Selection
■
Normally a positive PID input (feedback smaller than setpoint) leads to positive PID output. Parameter b5-09 can be used
to reverse the sign of the PID controller output signal.
No.
b5-09
Setting 0: Normal Output
A negative PID input causes an increase in the PID output (direct action).
Setting 1: Reverse Output
A positive PID input causes a decrease in the PID output (reverse action).
■ b5-10: PID Output Gain Setting
Applies a gain to the PID output and can be helpful when the PID function is used to trim the frequency reference (b5-01
= 3 or 4).
No.
