9/440 Resolver--based CNC/Drive System
5A-28
All external power connections to the 9/440 Resolver--based 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 volt AC or 24 volt DC. The logic power
is used to operate the processors in the system module, axis module
logic boards, and power the resolvers/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 9/440 resolver--based
control the voltages necessary to power the axis modules and the servo
motors.

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.
