Step 4: Configure the Line Side Converter
Step 4: Configure the Line Side Converter
In this step, you configure the line side converter. The line-side-converter-regulation parameters can usually be left at the
default values. If you are having issues or alarm/faults, refer to Appendix A > Line Side Converter Settings on page 57
.
Enter Line Side Converter Settings
1. Navigate to parameter 13:30 [Nom Line Freq]. Press the EDIT soft key.
2. Edit the nominal line frequency in Hertz, corresponding to the data collected in Table 1 on p a ge 8
.
3. Press the ENTER soft key.
4. Navigate to parameter 13:32 [AC Line kVA A]. Press the EDIT soft key.
5. Edit the supply transformer power rating in kVA, corresponding to the data collected in Table 1
.
6. Press the ENTER soft key.
7. Navigate to parameter 13:34 [AC Line Imped% A]. Press the EDIT soft key.
8. Edit the power source line impedance in percent, corresponding to the data collected in Table 1
.
9. Press the ENTER soft key.
10. At this point, the basic line side converter settings required for most applications are configured. You may
configure additional parameters such as:
• Current Rate Limit, parameter 10:227 [Current Rate Lim].
• Regen Power Limit, parameter 10:229 [Regen Power Lim]. Only for Flux Vector motor control modes.
• Motor Power Limit, parameter 10:230 [Motor Power Lim]. Only for Flux Vector motor control modes.
To determine the settings for these parameters, refer to either of the following:
• Connected Components Workbench™ (version 11 or later) software and the associated PowerFlex 755T
Startup Wizard.
• The PowerFlex Drives with TotalFORCE Control Programming Manual, publication 750-PM100
