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
®
does NOT detect this bit on Low, error 12 is
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.
6.3 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
