Operating the Inverter
4-11
605 Series Frequency Inverter
Forced Coast Stop
Using the /Coast Stop mode immediately disables the power stack, causing the load to coast to a
stop. The Inverter gives priority to the /COAST STOP signal. The /FAST STOP signal is
therefore ignored while /COAST STOP is active.
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.
Logic Stopping
The Inverter can be stopped by setting the /STOP to FALSE for a short time, (>100 ms). The
stop sequence continues even if the /STOP signal goes inactive before the Inverter is stopped.
Various combinations of stop logic are shown below.
POWER CIRCUIT DISABLED
SPEED DEMAND
REMOTE SETPOINT
Speed 0%
SPEED TRIM
/COAST STOP
