(1) Refer to your encoder manual for proper cable type and length.
(2) Due to the topology of the module’s input circuits, terminating the shield at the encoder end provides the highest immunity
to EMI interference. Connect EARTH ground directly to the encoder connector housing.
(3) The pullup resistor (R) value depends on the power supply value (VS). The table below lists the resistor values for typical
power supply values. These resistors must be located at the encoder end of the cable.
