Rockwell Automation 2364F Regenerative DC Bus Supply Unit (RGU) - Manual (Page 171)

Publication 2364F-5.01– October 2003
Programming Parameters D-27
123
Voltage Mode Select
[Volt Mode Sel]
This parameter selects the source voltage
command used to produce the Bus Reference
(P128), which determines the voltage that the
RGU should supply to the bus.
Parameter Type Sink (Read/Write)
Display Units None
Drive Units Display Units * 1
Factory Default 3
Minimum Value 0
Maximum Value 3
Related Parameters P122, P126, P128, P129, P207
The bus rate limiter shown is used to limit limit the bus
reference from changing to rapidly. The output of this
limiter is the Bus Reference (P128).
124
Minimum Bus Reference
[Min Bus Ref]
This parameter defines the minimum voltage
command value that can be sent as a Bus
Reference (P128).
This value is calculated by the RGU and is 95%
Parameter Type Source (Read/Write)
Display Units Volt
Drive Units Display Units * 4096/P16
Factory Default 0.85 x P16
Minimum Value 0.85 x P16
Maximum Value 1.15 x P16
Related Parameters P125, P126, P128, P129
of the greater of either the Nominal AC Line
Voltage (P10) multiplied by the square root of two,
or the Actual AC Line Volage (P14) multiplied by
the square root of two.
125
Maximum Bus Reference
[Max Bus Ref]
This parameter defines the maximum voltage
command value that can be sent as a Bus
Reference (P128).
This value is calculated by the RGU and is equal

to 115% of the Nominal AC Line Voltage (P10)
multiplied by the square root of two.
126
Bus Rate Reference
[Bus Rate Ref]
This parameter specifies the bus voltage to be
achieved. The value of this parameter is passed
through the bus rate limiter to ensure that the DC
bus voltage does not change too rapidly, resulting
in the value for P128 (Bus Reference).

Value Description
0 Bus Volt Cmd Selects the P207 (Bus Voltage
Command) as the input. By default,
P207 is set to the Nominal DC Bus
Voltage (P16).
1 Aux Volt Cmd Selects the value entered into P122
(Auxiliary Voltage Command).
2 Bus&Aux Cmd Selects the sum of P207 and P122.
3 Bus Ref Auto Selects the bus reference calculated
from P10, P14, P16, and P130.
