9/440HR CNC/Drive System
5B-29
All external power connections to the 9/440HR CNC/Drive are wired
through the system modules power strip, located behind the front cover in
the lower right corner. Input power is wired to this strip in two different
voltages:
24 V Logic Power -- this is 24 V AC or 24 V DC. The logic power is
used to operate the processors in the system module, axis module logic
boards, and power the encoders.
Drive Power -- this is 324-528 V AC, three phase, 50/60 Hz. The drive
power is used to supply the drive portion of the 9/440HR the voltages
necessary to power the axis modules and the servo motors.

PE System Ground Bar
DC+, INT, COL Shunt resistor connection. When the jumper exists between INT
and COL the internal 200 W shunt is used. When using the
optionally purchased 1000 W shunt the jumper is removed and
the new shunt is installed between DC+ and COL.
All connectors on the power strip support a maximum of AWG 12 gauge solid wire.
