4-4-2 Clearing a Trip
!WARNING
In the event that the Inverter trips, be sure to investigate the cause of this trip
thoroughly before clearing the trip. Not checking the cause may result in
unexpected operation. Refer to section
5-1 Troubleshooting using the LED
indicators
or section
5-2 Troubleshooting Using PROFIBUS Diagnostics
.
Step 3 You must always immediately clear the Run bit in your PLC program when a
rising edge is detected on Flt. If the Run bit is set when the trip condition is
cleared, the Inverter will immediately start running!
Step 4 Set the Rst bit in the STW register to clear the trip.
Table 37 Output Process Area when Clearing Trip
!WARNING
Always clear the Run bit (STW) in your PLC program on a rising-edge of Flt
(ZSW). Not doing so may result in the motor starting unexpectedly when the
trip is cleared via PROFIBUS or the "Stop/reset" button on the Inverter.
