34Control word bit 3 received from the active control
source.
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.
