circuit board.
To connector CPD1(IN) shown below, supply the power required for the
operator’s panel and general–purpose DI. To facilitate power
distribution, the power applied to CPD1(IN) is directly output to
CPD1(OUT). Use CPD1(OUT) if power distribution is required.

NOTE
1 Power connectors CPD1(IN) and CPD1(OUT) have the
same specification. On the actual printed circuit board, (IN)
and (OUT) are not distinguished from each other.
2 During operation, never turn off the +24 V power supply to
the connector. Otherwise, a CNC communication alarm is
issued. Ensure that +24 V is supplied either when or before
the power to the CNC is turned on, and that the +24 V supply
is removed either when or after the power to the CNC is
turned off.
