Parameter Encoder monitoring (Check Encoder)

An encoder monitoring can be activated via the parameter "Check encoder", as long as the used
SSI-encoder supports this function. After the last read encoder bit it is verified if the data line is
still at Low for at least one bit. If the UNIGATE
issued. For example it can detect a cable break or a not connected encoder. However, it can also
be a misconfigured bit length, or a too slow read out clock.

Hardware-wiring

The clock wires of the SSI-interface are placed onto the Tx-wires of the RS422-interface and the
data wires onto the Rx-wires at the UNIGATE
