Remarks
Internal power source: +15 Vdc ± 10% 120 mA, +12 Vdc ± 10% 120 mA (changeable on PC board 1 ) (Terminal:
PO, CM)
Speed Control Range:
OPCG11SPG
Terminals XA, XB and XZ are not in use unless used for a digital reference. They can be used for basic speed control and digital
follower control.
External power source: +12 Vdc (-10%) to +15 Vdc (+1-%) / 300 mA or less 2 (Terminal P1, CM)
Use external power source when more than one PG feedback card is used and the total input current exceeds
120 mA
Connect A- and B-phase output signal from pulse generator on
feedback side
Connect Z-phase output signal from pulse generator on feedback
side. When the pulse generator does not have Z-phase, these
terminals need not be connected.
Take note that the power source matches the specifications of the applied pulse generator
