n004 : Stopping Method
Selects the stopping method suitable for the application.
A. Ramp to STOP ( 0 ) : Deceleration to Stop
Upon removal of the FWD (or REV)
Run command, the motor decelerates
at the deceleration rate determined
by the time set in Decel Time 1
(n019 ), and DC injection braking is
applied immediately before stop. If
the decel time is too short or the load
inertia is too large, an overvoltage
(OV) fault may occur on a stop
command — the decel time must be
increased.
B. Coast to STOP ( 1 ) : Coast to Stop
Upon removal of the FWD (or REV) Run command, the motor coasts to rest.
