No-load Test Chapter 4

7. Press , and press in the Start Drive? dialog box to

confirm operation.

8. Record the output voltage in the HMI screen.

The value must not by more than ±10% of output voltage based on the

drive configuration.

9. Press the Set Frequency: input field. In the Set Freq: dialog box, enter a

value of “20” and press . Press to confirm.

10. Record the output voltage in the HMI screen.

Repeat this process for 30, 40, and 50 Hz (or 60 Hz).

11. Run the drive for 30 minutes at 50 Hz or 60 Hz (dependent on system

frequency).

12. Switch off customer-supplied control power.

The Control Power Supply Loss warning appears in the HMI.

The K8 relay will automatically switch-off and the K9 relay will switch on

to supply control power from the isolation transformer tertiary winding.
