16The start and stop commands are taken from an external
(DDCS) controller.
Note: The start signal is always edge-triggered with this
setting regardless of parameter 20.7 Ext2 start trigger type.
DDCS controller
Edge / uint16Defines whether the start signal for external control location
EXT2 is edge-triggered or level-triggered.
Note: This parameter is only effective when parameter
20.6 Ext2 commands is set to In1 Start, In1 Start; In2 Dir,
In1 Start fwd; In2 Start rev, or Control panel.

Selects the way the motor is stopped when the run enable
signal switches off.
The source of the run enable signal is selected by
parameter 20.12 Run enable 1 source.
Run enable stop
mode

0Stop by switching off the output semiconductors of the
drive.
The motor coasts to a stop.
WARNING!
If a mechanical brake is used, ensure it is safe to
stop the drive by coasting.
Coast
1Stop along the active deceleration ramp. See parameter
group 23 Speed reference ramp (page 271).

DI5 (95.20 b9) / uint32
Selects the source of the external run enable signal. If the
run enable signal is switched off, the drive will not start. If
already running, the drive will stop according to the setting
of parameter 20.11 Run enable stop mode.
1 = Run enable signal on.
Note: The warning that indicates a missing signal can be
suppressed using parameter 20.30 Enable signals warning
function.
