■ b5-07: PID Offset Adjustment
Sets the offset added to the PID controller output. Set as a percentage of the maximum
frequency.
■ 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.
Note: Effective in preventing oscillation 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
reduces the responsiveness of the drive.
■ b5-09: PID Output Level Selection
Normally, the output of the PID function increase whenever the PID input is negative
(feedback below setpoint). Using b5-09 the PID controller can be set up for applications that
require opposite operation.
Setting 0: Normal Output
A negative PID input causes an increase in the PID output (direct acting).
Setting 1: Reverse Output
A negative PID input causes an decrease in the PID output (reverse acting).
■ 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). Increasing b5-10 causes the PID function to have a
greater regulating effect on the frequency reference.
