9.3.2 Status Messages - Operating Mode
Table 95: Operating Mode
The drive requires external commands to execute functions. The start/stop commands are sent via the control
terminals and/or the serial communication.
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.
The drive does not react to any control signal until [Auto On] or [Hand On] is pressed.
