Signal connections of the signal terminal block
INFORMATION
- If the inputs of the inverter are supplied by an external 24 V voltage supply or PLC, you must connect the GND reference potential to terminals 7 and 9. The control electronics of the inverter work in isolated fashion.
- If the STO is controlled by an external voltage supply, wire it according to the connection examples in chapter Disconnection of a single drive.
- If you are using a TTL or HTL encoder, do not connect its GND signal to terminal 7 or 9.
