Safe Operation mode
This safety feature is used as a Run Enable/Disable input. When a digital input is set to 13 (Run
Enable), the inverter will only operate when the input is closed (Enabled). The input must be closed
to recognize other digital input functions. This feature is also useful for interlocking operation with
other equipment.
A stop mode can be selected (Ad.71, Run Dis Stop) if the Run Enable input is opened during
operation. Selections include coasting to a stop, Quick Stop and Quick Stop Resume. The
deceleration time (Ad.72, Q-Stop Time) can be set for the Quick Stop functions..
