Selecting The Stopping Method; Stopping Method Selection (N005) - Omron V7-IP65 User Manual

If the FWD/REV Run Command is turned ON after turning the Motor
Switching Command ON (or OFF) but before the Motor Selection Mon-
itor turns ON (or OFF), Inverter output will begin immediately after the
Motor Selection Monitor turns ON (or OFF).

* Changing the frequency reference while running
Upon termination of a FWD (REV) Run Command, the motor deceler-
ates at the deceleration rate determined by the time set in Deceleration
Time 1 (n020) and DC injection braking is applied immediately before
stopping. DC injection braking is also applied when the motor deceler-
ates because the frequency reference is set lower than the Min. Output
Frequency (n016) when the FWD (REV) Run Command is ON. If the
deceleration time is short or the load inertia is large, an overvoltage
(OV) fault may occur at deceleration. In this case, increase the decelera-
tion time or install an optional Braking Resistor.
