4-2 Start-Up After Repair
Testing with the External DC
Power Supply Without Load
(Optional)
This is a low current - low risk test for the Output Power Module and drive
Control board. It requires the recommended High Voltage DC Test Power
Supply.
1. Verify that the DC Test Power Supply is de-energized.
2. Connect the power supply’s DC+ to the drive’s DC+ terminal and the
power supply’s DC- to the drive’s DC- terminal.
3. Set the power supply voltage setting to zero.
4. Switch on the external DC Test Power Supply.
5. Slowly increase the DC Test Power Supply output voltage to the drive’s
nominal DC bus voltage (650V dc for drives with 380-500V ac input or
775V dc for drives with 600-690V ac input).
6. 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)
7. Make configuration changes which allow the HIM to issue start and
speed commands.
8. Make configuration changes which allow operation without an encoder
and motor.
9. Start the drive, by pressing (the start button).
10.Increase the speed command from zero to base speed, by pressing
(the up button).
11.Stop the drive, by pressing (the stop button).
12.Re-configure the drive to suit the application.
13.Decrease the DC Test Power Supply output voltage to zero. Wait until
DC bus voltage has decreased to zero. Switch off the external DC power
supply.
