Stopping Method - YASKAWA V7 Technical Manual

5.24 STOPPING METHOD

n005 : Stopping Method
Selects the stopping method suitable for the application.
Setting
A. Data 0 : Deceleration to Stop
Upon removal of the FWD (REV) Run
command, the motor decelerates at the
deceleration rate determined by the time
set in Decel Time 1 (n020 ), and DC
injection braking is applied immediately
before stop. If the decel time is too short
or the load inertia is too large, an over-
voltage (OV) fault may occur on a stop
command — the decel time must be
increased.
B. Data 1 : Coast to Stop
Upon removal of the FWD (REV) Run command, the motor coasts to rest.
