8-20 Configuring Your 1394 Analog Servo System
[Shunt P]
Shunt resistor continuous power rating.
Active on all Smart Power 22 kW systems and 5
and 10 kW (Series C or later) systems.
This parameter only needs to be configured
when you are using custom resistors.
Note: [Shunt Type] must be set to "custom shunt"
before making modifications to this shunt
parameter (44-48).

[Shunt Peak Usage]
This parameter shows the peak usage of the
shunt resistor over the last ten seconds. (%) This
parameter can be observed to determine
proximity of usage to fault condition. Warning is
set at 80%. Fault is set when value reaches
105%.
Active on all Smart Power 22 kW systems and 5
and 10 kW (Series C or later) systems.

[Shunt R]
Shunt resistor resistance. Set this parameter
only when using a custom resistor.
Active on all Smart Power 22 kW systems and 5
and 10 kW (Series C or later) systems.
Note: [Shunt Type] must be set to "custom shunt"
before making modifications to this shunt
parameter (44-48).
