NOTICE
Material damage when selecting the incorrect encoder supply voltage
Once the encoder has been commissioned, the supply voltage (5/24 V) set for the encoder
is activated on the SMC30 module. The encoder may be damaged, if a 5 V encoder is
connected and the supply voltage has not been set correctly (bit 20 = "Yes," bit 21 = "No").
• Set the correct supply voltage for the connected encoder.
