Rockwell Automation 2364F Regenerative DC Bus Supply Unit (RGU) - Manual (Page 89)

Publication 2364F-5.01– October 2003
Setting Up Your RGU 8-5
Utility AC Line Frequency [P13]
Set the Utility AC Line Frequency (P13) to the frequency of the AC line.
Measured AC Line Voltage [P14]
Using a meter, measure the AC line voltage. Compare the Measured AC Line Voltage (P14) with the meter
reading. Determine the adjustment that needs to be made in the RGU (by percent).
AC Line Voltage Calibration [P15]
Set this parameter to adjust the value in P14. If this calibration parameter is changed, check the Measured
AC Line Voltage (P14) again.
AC Line Low Setting [P26]
Verify that the AC Line Low Setting (P26) is at an acceptable voltage. Typically, the default setting should be
sufficient.
AC Line High Setting [P27]
Verify that the AC Line High Setting (P27) is at an acceptable voltage. Typically, the default setting should be
sufficient.
DC Bus Low Setting [P28]
Verify that the DC Bus Low Setting (P28) is at an acceptable voltage. Typically, the default setting should be
sufficient.
DC Bus High Setting [P29]
Verify that the DC High Setting (P29) is at an acceptable voltage. Typically, the default setting should be
sufficient.
Iq Feedback [P100]
Since all of the inverters are disconnected at this time, this value should be 0.0%. Determine the offset that
will be required.
Iq Feedback Offset [P99]
Set this parameter to adjust the value of P100 to equal 0.0%. If this offset parameter is changed, check the Iq
Feedback (P100) again.
Bus Feedback [P141]
Using a meter, measure the DC bus voltage. Compare the Bus Feedback (P141) with the meter reading.
Determine the adjustment that needs to be made in the RGU (by percent).
Bus Voltage Feedback Calibration [P144]
Set this parameter to adjust the value in P141. If this calibration parameter is changed, check the Bus
Feedback (P141) again.
External Capacitance [P203]
Determine the maximum amount of capacitance that is expected to be on the DC bus at any one time
(a table of inverter capacitances can be seen in Appendix B of this manual).
Important: If additional inverters are added in the future, this parameter must be updated.
Example
An RGU (catalog number 2364FA-MNB) is connected to a 1336 FORCE (100HP), 1336 PLUS (150HP), and
SA3100 (150HP).
In Appendix A, we find that the catalog number (2364FA-MNB) indicates the unit is a 460V AC M-code RGU.
Using the capacitor bank tables in Appendix B (for 460V AC lineups), we have the following values:
1336 FORCE (100HP)
900uf/10
1336 PLUS (150HP) 1200 uf/10
SA3100 (150HP) 1200 uf/10
Total Ext. Capacitance
3300 uf/10 (Example only)
