Setting Up the Parallel Configuration
Enabling the RGU
After the basic startup procedure has been completed, the RGU can
be enabled. The RGU can be enabled by three different methods.
1.
Send an enable command to the Host Command Word by setting
the Enable Cmd bit (P32 bit 1 = 1).
2.
If the Remote/Local Selector has been set to Local Only (P8=0),
reset the RGU. The unit will automatically enable after the reset.
3.
If the Remote/Local Selector has been set to Remote+Local
(P8=1), press the green start key on a HIM, GPT, or DrivePanel
(DriveTools). Note that P224 and P225 must be configured
appropriately for this.
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 are given in Appendix A). The total external capacitance must be divided
among the number of RGUs in the configuration.
Important: If additional inverters are added in the future, this parameter must be updated.
Example
A parallel configuration (catalog number 2364PA-T5B) is connected to a 1336 FORCE (100HP), 1336 PLUS
(150HP), and SA3100 (150HP).
In Appendix A, we find that the catalog number (2364PA-T5B) indicates two 460V AC M-code RGUs in the
configuration. Using the capacitor bank tables in Appendix A (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
Since there are two RGUs, half of this value (1650 uf/10) would be programmed into P203 of each RGU.
SCANport Port Enable Mask [P224]
Verify that the appropriate SCANport ports are active. Note the following bits:
SCANport 1 (bit 1)
Activates J10 on the main control board (used for HIM, GPT, etc. connection).
SCANport 2 (bit 2)
Activates J9 on the main control board (used for HIM, GPT, etc. connection).
SCANport 6 (bit 6)
Activates J8 on the main control board (used for optional SCANport interface board).
SCANport Enable Mask [P225]
This setting determines if the start key on a connected SCANport device can be used to enable the RGU.
Verify that the appropriate bits are set to 1.
Note: P5 (Remote/Local Selector) and P224 (SCANport Port Enable Mask) must be set accordingly if
a programming terminal/SCANport device will be used to enable the RGU.
SCANport Clear Fault Mask [P226]
This setting determines which SCANport ports (i.e. J8, J9, or J10) can be used to clear faults in the RGU.
Verify that the desired bits are set to 1. P224 (SCANport Port Enable Mask) must be set accordingly.
SCANport Reset Mask [P227]
This setting determines which SCANport ports (i.e. J8, J9, or J10) can be used to reset the RGU. Verify that
the desired bits are set to 1. P224 (SCANport Port Enable Mask) must be set accordingly.
