Can anybody tell me how to wire the VFD Altivar 31 ATV31HU22N4 with the Twido PLC TWDLCAA24DRF. Also If one have a wiring diagram for the inputs and outputs of VFD and PLC that I have mentioned.
 
If you want to use 2 wire control just wire from the VFD (+24v) to the common off the output and then from q0 of the twido to L1 of the VSD. Just switch the output q1 on the the drive should start. When the run signal falls away the drive will stop.

You can use ur R2A and R2C contacts on the VSD to get a fault input to the Twido
