PID Output
Sets the maximum output
Limit
possible from the entire PID
controller. Set as a percentage
PID Limit
(%) of maximum frequency.
PID Offset
Sets the amount of offset of the
Adjustment
output of the PID controller.
Set as a percentage (%) of
maximum frequency.
The offset is summed with the
PID Offset
PID output. This can be used
to artificially kick-start a slow
starting PID loop.
PID Primary
Sets the amount of time for
Delay Time
the filter on the output of the
Constant
PID controller.
Note: The offset is summed
with the PID output.
This can be used to
PID Delay
artifically kick-start a
Time
slow starting PID loop.
Note: Normally, change is not
required.
PID Output
Determines whether the PID
Level
controller will be direct or
Selection
reverse acting.
0: Normal Output (direct
acting)
Output Level
1: Reverse Output (reverse
Sel
acting)
PID Output
Sets the output gain of the
Gain Setting
PID controller.
Output Gain
PID Output
0: Zero Limit (when PID
Reverse
output goes negative,
Selection
Drive stops). Zero Limit is
automatic when reverse
prohibit is selected using
Output Rev
b1-04.
Sel
1: Reverse (when PID goes
negative, Drive reverses).
PID
0: Disabled (no detection of

loss of PID feedback)
Reference
