07-09 =0: Deceleration to stop
When a stop command is issued, the motor will decelerate to the minimum output frequency (01-08) Fmin and
then stop. Deceleration rate depends on the deceleration time (factory default: 00-15).
When the output frequency reaches the DC braking stop frequency (07-06) or the minimum output frequency
(01-08), DC injection braking is activated and the motor stops.

07-09 =1: Coast to stop
When a stop command is issued, the motor will coast to a stop. Stop time depends on motor load and friction of
the system.
Notes:
The inverter waits for the time set in the minimum baseblock time (07-18) before accepting the next run
command.
In SLV mode (00-00=2) the speed search function is automatically enabled upon the next run command.
