Three–phase power to the 9/440HR must be 324-528 V ac, 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.
All power connectors on the 9/440HR power strip accept AWG 12 gauge
solid wire. Refer to local codes for required wire type and gauge.
Grounded vs Ungrounded Three–phase
The 9/440HR CNC/Drive comes from the factory set for three–phase
grounded systems. If your facility uses an ungrounded three–phase
360/480 volt system, you must move a jumper in the 9/440HR system
module. This jumper will connect an internal resistor that helps keep high
voltage static, that can be typical of ungrounded three phase systems, from
building up in the system module.
