When unipolar HTL encoders are used, A*, B*, and R* on the terminal block must be jumpered with
M_Encoder (X531)

Because the physical transmission properties are more robust, the bipolar connection should
always be used. The unipolar connection should only be used if the encoder type does not output
push-pull signals.
WARNING
Electric shock due to unconnected cable shields
Hazardous touch voltages can occur through capacitive cross-coupling due to unconnected
cable shields.
• Attach the cable shield to the component via terminals for the encoder system
connection.
