+24VDC Power Connections for Series 15i Control
Note
This information applies only to the Series 15i CNC. It does not apply to
the Series 16i/18i and 21i CNCs or Power Mate i Motion Controllers.
For information on the Series 16i/18i and 21i CNCs or Power Mate i
Motion Controllers, please refer to Pages 1-11 through 1-15.
The Series 15i CNC uses its own power supply which operates from 200 volts ac. The power supply is
similar in style to previous generations of Series 15 controls. The power supply mounts in the CNC logic
rack and provides power to the Series 15i circuit boards mounted in the rack. The power supply also
provides a switched +24VDC that can be used to power the LCD unit, Operator Panel, and other GE Fanuc
devices requiring a switched +24VDC. The power supply contains connections to be wired directly to the
Control ON and OFF pushbuttons mounted on the Operator Panel.
The North American Operator Panel includes circuitry to provide a switched +24VDC to be used with the
Series 16i/18i and 21i CNCs. This circuitry does not apply when the Operator Panel is used with the Series
15i control. Instead, the Operator Panel mounted Control ON and OFF pushbuttons will be wired directly
to the Series 15i power supply. The +24VDC required by the Operator Panel may be sourced from the
Series 15i power supply.
When used with the Series 15i control, the Operator Panel may be ordered with Cable Kit 44A739097-G01.
This kit contains the following items:
