Rockwell Automation 2364F Regenerative DC Bus Supply Unit (RGU) - Manual (Page 175)

Publication 2364F-5.01– October 2003
Programming Parameters D-31
147
Single Phase Detection Threshold
[1 Phase Threshold]
This parameter sets the threshold that a single
phase trip will occur. The Single Phase Detector
monitors the internal Phase Lock Loop (PLL) error
signal.
Parameter Type Source (Read/Write)
Display Units None
Drive Units Display Units * 1
Factory Default 400
Minimum Value 100
Maximum Value 1000
Related Parameters P148
A single phase trip occurs when the PLL error
exceeds the threshold set by P147 for a time
duration set by P148.
148
Single Phase Detection Delay Before Fault
[1 Phase Err Delay]
Time delay between detection of single phase
operation and the declaration of a fault.
Parameter Type Source (Read/Write)
Display Units SEL
Drive Units Display Units * 200
Factory Default 3.0
Minimum Value 0.1
Maximum Value 60
Related Parameters P147
149-150
P149-P150 are for internal use only.
151
Real Power
[Real Power]
This parameter indicates the real power being
supplied through the DC bus.
This value is calculated using the AC line voltage
(P14) and the active AC current
(P100 x P11).
Parameter Type Source (Read Only)
Display Units kW
Drive Units Display Units * 1
Factory Default 0.0
Minimum Value -3276.8
Maximum Value 3276.7
Related Parameters P11, P14, P100
For example, if a K-code RGU has a 380V AC
line voltage in P14, and if P100 indicates that
the active current is 97% of the rated line
voltage (182A AC), then P151 would equal 67kW
(380 x 0.97 x 182 = 67kW).
152
Reactive Power
[Reactive Power]
This parameter indicates the reactive power being
supplied through the DC bus.
This value is calculated using the AC line voltage
(P14) and the reactive current
(P106 x P11).
Parameter Type Source (Read Only)
Display Units kVAR
Drive Units Display Units * 1
Factory Default 0.0
Minimum Value -3276.8
Maximum Value 3276.7
Related Parameters P11, P14, P106
153
Apparent Power
[Apparent Power]
This parameter indicates the apparent power
being supplied through the DC bus.
This value is calculated using the Real Power
(P151) and the Reactive Power (P152).
Parameter Type Source (Read Only)
Display Units kVA
Drive Units Display Units * 1
Factory Default 0.0
Minimum Value 0.0
Maximum Value 6553.5
