320 VDC Bus Connection
Refer to the
P70360 (AC) High Performance Micro-stepping Drive Reference Guide
, available
from
ni.com/manuals
or from the Product Support Package CD in your kit, for 160 VDC bus
connection. This configuration is required for third-party motors with 7 to 30 mH inductance.
Connecting DC Power
Power on your DC or AC power supply. Once powered, the P7000 drive enters a configuration
mode that causes the LED to flash and the motor to audibly squeal. This is expected operation,
as the drive is measuring the motor windings to optimize its settings. Once complete, the status
LED should illuminate green. If it is not, refer to the
section.
