controller. Set as a percentage
(%) of maximum frequency.

PID Offset
Adjustment

Sets the amount of offset of the
output of the PID controller.
Set as a percentage (%) of
maximum frequency.
The offset is summed with the
PID output. This can be used
to artificially kick-start a slow
starting PID loop.

PID Primary
Delay Time
Constant

Sets the amount of time for
the filter on the output of the
PID controller.
Note: The offset is summed

with the PID output.
This can be used to
artifically kick-start a
slow starting PID loop.

Note: Normally, change is not

required.

Selection

0: Zero Limit (when PID

output goes negative,
Drive stops). Zero Limit is

of PID feedback,
operation continues

energized)

2: Fault (detection of loss of

PID feeedback, coast to
