Looping via terminals X410A

In some cases, encoder power supply must be supported or effected by an external
power supply. This is a good idea especially in the case of encoders with medium
power demand (0.5...2 W) or when many consumers are connected to the signal ter-
minals.
An external DC 24 V power supply can be connected to terminals X410A.1 (DC 24 V)
and X410A.2 (ground). Via this power supply, a connected encoder can be powered.
BONFIGLIOLI VECTRON recommends connecting an external power supply.

Connect the power supply for the encoder to terminals X410A.1 and

and X210A.2) is not sufficient for powering the EM-ABS-01 module and the

level higher than 2 W or more than DC 12 V, it must be connected to an
external power supply directly. Non-fulfillment of this requirement may
result in dangerous plant states.
