Note:
• If the drive is running in fieldbus control, switching bit
3 off effectively removes both the start and run enable
signals.
• In this case, the stop mode is determined by either
20.11 Run enable stop mode or 21.3 Stop mode,
whichever mode has higher priority. The order of stop
modes from highest to lowest priority is Coast –
Torque limit – Ramp.
In case the active source is the control panel, PC tool
or drive I/O, the run enable signal is always on.

Selected / uint32Selects the source for the start enable signal.
1 = Start enable.
With the signal switched off, any drive start command is
inhibited. (Switching the signal off while the drive is running
will not stop the drive.)
Note:
• If a level-triggered start command is on when the start
enable signal switches on, the drive will start. (An
edgetriggered start signal must be cycled for the drive
to start.) See parameters 20.2 Ext1 start trigger type,
20.7 Ext2 start trigger type and 20.29 Local start
trigger type.
• The warning that indicates a missing signal can be
suppressed using parameter 20.30 Enable signals
warning function.
