Note
Operation of unipolar HTL encoders
When unipolar HTL encoders are used, terminal block A*, B*, and R* must be jumpered with
M encoder (-X531).

max. connectable cross-section #16 AWG (1.5 mm²)
When using unipolar HTL encoders, at the terminal block A*, B*, R* must be connected to (jumper) M_Encoder (X531)
Because the physical transmission media is more robust, the bipolar connection should always be used. The unipolar
1)
connection should only be used if the encoder type does not output push-pull signals.
