Rockwell powerflex 700s User Manual

4-2 Start-Up After Repair
Before Applying Power to
the Drive
1. Check the DC bus voltage at the Power Terminal Block by measuring
between the +DC and -DC terminals, between the +DC terminal and the
chassis, and between the -DC terminal and the chassis. The voltage
must be zero for all three measurements.
2. Perform the forward and reverse biased diode tests using a digital
multimeter. Refer to Conducting Forward and Reverse Biased Diode
Tests for Major Power Components on page 2-3.
Testing Without the Motor
This test allows you to measure several operating parameters and diagnose
problems without connecting the motor to the drive.
1. Verify that the input power wiring and grounding is connected.
2. Verify that the motor cables are disconnected.
3. Energize the drive.
4. Measure the DC bus voltage and verify that the value is reflected in:
– parameter 306 [DC Bus Voltage] (700S)
– parameter 012 [DC Bus Voltage] (700H)
5. Make configuration changes that allow the HIM to issue start and speed
commands.
6. Make configuration changes that allow operation without an encoder
and motor.
7. Start the drive, by pressing (the start button).
8. Increase the speed command from zero to base speed, by pressing
(the up button).
9. Measure the output voltage on each phase and verify that it is balanced.
If it is unbalanced troubleshoot the drive.
10. Stop the drive, by pressing (the stop button).
11. Re-configure the drive to suit the application.
