9.9 Stop Methods
Coast to Stop
Coast to stop lets the motor slow at its natural rate, with no control from the soft
starter. The time required to stop will depend on the type of load.
TVR Soft Stop
Timed voltage ramp reduces the voltage to the motor gradually over a defined time.
The load may continue to run after the stop ramp is complete.
Timed voltage ramp stopping can be useful for applications where the stop time
needs to be extended, or to avoid transients on generator set supplies.

Adaptive Control for Stopping
In an adaptive control soft stop, the VersiStart p III controls the current in order to
stop the motor within a specified time and using a selected deceleration profile.
Adaptive Control can be useful in extending the stopping time of low inertia loads.
The first Adaptive Control stop will be a normal soft stop. This allows the
VersiStart p III to learn the characteristics of the connected motor. This motor data
is used by the VersiStart p III during subsequent Adaptive Control stops.
If replacing a motor connected to a VersiStart p III programmed for Adaptive Control
starting or stopping, the starter will need to learn the characteristics of the new
motor. Change the value of parameter 1B
Motor Full Load Current or parameter 2L
Adaptive Control Gain to initiate the re-learning process. The next start will use
constant current and the next stop will use timed voltage ramp.
