Programming Parameters D-19
85
P85 is for internal use only.
86
Transistor Junction Temperature
[Abs Junct Temp]
This parameter indicates the calculated IGBT
junction temperature. This value is used by the
fault status parameters to indicate when high and
excessive temperatures occur.
Parameter Type Source (Read Only)
Display Units degC
Drive Units Display Units * 1
Factory Default 0
Minimum Value -50
Maximum Value 150
87
Heatsink Temperature
[Heatsink Temp]
This parameter indicates the measured heatsink
temperature. This value is used by the fault status
parameters to indicate when high and excessive
temperatures occur.
Parameter Type Source (Read Only)
Display Units degC
Drive Units Display Units * 1
Factory Default 0
Minimum Value -50
Maximum Value 127
88
Auxiliary Iq Current Limit
[Aux Iq Limit]
This parameter specifies the limit imposed on P89
(Auxiliary Iq Current Command).
The value of this parameter (current limit) is
displayed as a percentage of the Rated AC Line
Current (P11).
Parameter Type Sink (Read/Write)
Display Units % of P11
Drive Units Display Units * 5120/100
Factory Default 150.0
Minimum Value 0.0
Maximum Value 150.0
Related Parameters P11, P89
This parameter is only activated when Aux
Limit is selected in Host Mode (P35 bit 2 = 1).
89
Auxiliary Iq Current Command
[Aux Iq Command]
This parameter can be used to send an Iq
command (current reference) to the current limiter.
This command can passed as the total Iq
command, or can be added to the PI regulator
value (P121, Voltage Loop PI Output).
Parameter Type Sink (Read/Write)
Display Units % of P11
Drive Units Display Units * 5120/100
Factory Default 0.0
Minimum Value -120.0
Maximum Value 120
Related Parameters P88, P90, P273
See Chapters 1, 9
The value entered into this parameter is used
only when ‘PI +Aux Cmd’ or ‘Aux Iq Cmd’ is
selected in the Iq Mode Select (when P90 = 1
or P90 = 2).
This parameter can receive the Iq command
from another RGU through P273 (RGU-to-RGU
Receive 1, Indirect 1).
90
Iq Mode Select
[Iq Mode Select]
This parameter selects the current reference input
to be passed to the current limiter.
Set this parameter to one of the values listed
below.
Parameter Type Sink (Read/Write)
Display Units None
Drive Units Display Units * 1
Factory Default 0
Minimum Value 0
Maximum Value 3
Related Parameters P89, P94, P121
Value Description
0 Lin PI Out Selects the PI regulator output (P121). This is the normal selection for a standalone or master RGU.
1 PI + Aux Cmd Selects the PI regulator output value plus the Auxiliary Iq Command value (P121+P89). This allows P89 to be used as a trim value.
2 Aux Iq Cmd Selects the Auxiliary Iq Command (P89). This is normally used by a slave RGU which is receiving its Iq commands from a master RGU.
3 No Iq Cmd Selects 0 as the Iq Command
