Stand-by
The drive does not react to any control signal
until [Auto On] or [Hand On] is pressed.
The start/stop commands are sent via the
control terminals and/or the serial communi-
cation.
The navigation keys on the LCP can be used
to control the drive. Stop commands, reset,
reversing, DC brake, and other signals applied
to the control terminals override local control.
