AC890PX AC Drive
The Trip Condition
When a trip condition is detected, a similar stopping method to NOT COAST STOP is used. The power stack cannot be re-
enabled until the trip condition has been cleared and successfully reset.
Refer to Chapter 8: “Trips and Fault Finding” for further details.
Logic Stopping
The drive can be stopped by setting the NOT STOP to FALSE for a short time, (>100 ms). The stop sequence continues even
if the NOT STOP signal goes inactive before the drive is stopped. Various combinations of stop logic are shown below.
