D-26 Programming Parameters
121
Voltage Loop PI Output
[PI Reg Out]
This parameter stores the output from the PI
regulator. When the P90 (Iq Mode) equals 0 or 1,
this value is passed through the current limiter to
determine the Iq Reference (P96).
Parameter Type Source (Read Only)
Display Units % of P11
Drive Units Display Units * 5120/100
Factory Default 0.0
Minimum Value -640.0
Maximum Value 640.0
Related Parameters P90, P96, P118, P119, P120
The diagram shows how the PI regulator is
arranged, and shows how the value for P121 is
determined.
See the P90 listing for more information about
this parameter.
122
Auxiliary Voltage Command
[Aux Volt Cmd]
This parameter defines an auxiliary voltage that
can be commanded for the DC bus. The value
entered into this parameter can be used to
command a specific bus voltage (when P123 = 1)
or can be used to add to the Bus Voltage
Command in P207 (when P123 = 2).
Parameter Type Sink (Read/Write)
Display Units Volt
Drive Units Display Units * 4096/P16
Factory Default 0
Minimum Value -1.15 x P16
Maximum Value 1.15 x P16
Related Parameters P123, P126, P207
To use this parameter as an auxiliary bus voltage, To use this parameter as a supplement to the
enter the bus voltage that is needed during Bus Voltage Command (P207) during particular
particular events then program P123 to equal 1 events, enter the bus voltage to be added to P207
during those events. and program P123 to equal 2 during those events.
