35.3.1 RS422 mode wiring

To run the counter module in RS422 mode, follow the steps below:

 Power the XN300 slice module with 24 VDC by connecting the power

supply to the 24V incremental encoder supply and GND pins on terminal

X5 (+24 V (X1/X2)).

 Connect the XN300 slice module's 5 V and 0 V pins to the incremental

encoder's positive and negative potentials.

 Connect the incremental encoder's A, A

, B, B, R, R output signals to the

corresponding pins on the XN300 slice module.

 Use the control software to configure the device so that it runs in RS422

mode.

Check to make sure that the encoder is suitable for operation

with this module. To do this, compare the technical data for the

encoder with the specifications for the XN300 slice module.
