Coast Stop (B9)
This is achieved by removing 24V from Terminal B9.
The stack is automatically quenched and the contactor is opened. The motor coasts to a stop.
Note: The motor coast stop rate is dictated by the motor inertia - the drive does not control the
motion.
Standstill
Refer to Chapter 6: “Programming Your Application” -
STANDSTILL.
The Trip Condition
When a trip condition is detected, a similar stopping method to Coast Stop is used. The power
stack cannot be re-enabled until the trip condition has been cleared and successfully reset.
Refer to Chapter 7: “Trips and Fault Finding” for further details.
