NOTICE
The PTC input is not isolated. Only PTCs featuring safe isolation from
the motor winding as per EN61800-5-1 may be connected.
BONFIGLIOLI servo motor types BMD, BCR and BTD feature safe
isolation from the motor winding.
NOTICE
The maximum power used by the ANG DC 24 V supply must not
exceed 4 W. Encoder power supply voltage is provided by the ANG
DC 24 V supply and must be considered in the power demand calcu-
lation in addition to the ANG digital signals.
Bonfiglioli Vectron recommends connection of an external DC 24 V
power supply to the relevant control terminals in order to supply the
digital signals directly.
Note encoder manufacturer's specifications on power consumption.
