Setting Up Parameters
Actual Command
Displays the Torque command after all limiting. This command is used by the current loop to
generate Motor Torque.
Drive Status Group
Foldback RMS
This parameter accurately models the RMS loading of the drive and motor. When it reaches
100 percent, current foldback will be activated.
Shunt Power RMS
This parameter models the thermal heating and cooling of the drive internal shunt. This
parameter indicates the percent of shunt capacity utilization and is based on the Heat Sink
RMS value. When this value reaches 100 percent the drive will generate an RMS Shunt
Power Fault.
Heatsink RMS - EN Only
This parameter models the thermal utilization of the heatsink by the power stage. It
determines the amount of thermal capacity available for the Regen Shunt Resistor. A display
of 10 percent heatsink capacity remaining for use by the shunt resistor. When this value
reaches 100 percent or higher, no capacity is left for the shunt resistor and a shunt resistor and
a shunt fault will occur as soon as the shunt is activated.
Segment Display
Character currently being displayed by the status display on the front of the drive.
Actual Operating Mode
This parameter returns the actual (or current) operating mode or state of the drive. This is
determined by the Operating Mode Default, Alternate Operating Mode, Input Functions
which override the operating mode, fault conditions, function modules or disabling the drive.
Bus Voltage - Epsilon Only
Displays the actual measured voltage on the DC power bus.
