Power supply ≤ 5 V.
–
Orange Continuou
s light
The electronics power supply for the encoder system is
available.
Power supply > 5 V
Notice
Make sure that the connected encoder can be operated with
a 24
V power supply. If an encoder that is designed for a 5 V
supply is operated with a 24 V supply, this can destroy the
encoder electronics.
