You may want to trip the Inverter from your PLC program. The PROFIdrive
device profile does not provide a standard interface to achieve this, but you
can use the Modbus coil number 0003h to generate an external trip (EXT):
Follow the instructions in section 4-3-2 Mapping Coil Data 0 to map Coil data
0 into PZD3.
Set bit 3 (EXT) of Coil data 0 which has been mapped into PZD3 to trip the
Inverter.

Notice that the Inverter trips with an E12, the Flt bit is set and the Rdy bit
cleared.
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 unex-
pected operation. Refer to section 5-1 Troubleshooting using the LED indica-
tors or section 5-2 Troubleshooting Using PROFIBUS Diagnostics.
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!
Set the Rst bit in the STW register to clear the trip.
