Drive is in AUTO Mode, Lag operation and
is holding the speed at the time it made the
switch from being a lead drive to a lag. Speed
is held until P9-07 time expires. The Home

PID Feedback via Network
The Network PID Feedback comes from a drive on the network with a valid analog PID feedback source and can be used as
the primary or secondary feedback source for a networked drive.
Set P9-02 to 0 if a drive has an analog PID feedback device installed and switching to network as a backup is not desired.
If a drive has an analog PID feedback device installed and the network PID feedback is considered as a backup, set P9-02 to
1 for no alarm message when switched and set P9-02 to 2 for an alarm.
Set P9-02 to 3 if a drive has no analog PID feedback device installed and relies solely on the analog PID feedback of another
networked drive.
Note: Connect an analog PID feedback device to each drive for best performance.
