The SMX module supports encoder voltages of 5V, 8V, 10 V, 12V and 24V, which are internally
monitored in accordance with the chosen configuration.
If an encoder system is not supplied through the SMX module, a supply voltage still needs to be
connected to terminal X13 or X15 and configured accordingly.
The encoder supply must be protected with a fuse of max. 2A.
Safety note:
• The GND connection of the encoder must be connected to the GND of the SMX
