Calculated control variables
The Innovation Series drive contains a set of variables that are calculated from the
primary motor parameters but are not exact reflections of the primary parameters.
These calculated variables are used in motor control and protective functions. The
values of the variables are calculated at drive initialization after power up or a hard
reset.
The following table lists the variables calculated from the primary value parameters:
Parameter Description
100% Motor torque
Motor torque at motor nameplate conditions. Newton-
meters or Pound-feet
100% Flux Motor flux at motor nameplate conditions. Volts/hertz
100% Torque current Motor torque current at motor nameplate conditions.
RMS amps
100% Flux current Motor flux current at motor nameplate conditions.
RMS amps
100% Slip
Motor slip at motor nameplate conditions.
Radians/second
Display meter scaling parameters
The Innovation Series drive contains a set of parameters that specify the scaling for
the DDI and toolbox display meters. These parameters are calculated from the
primary motor and application parameters. They are calculated within the Drive
Commissioning wizard or the Per Unit Setup wizard. If any of the primary data
parameters is modified outside the Drive Commissioning wizard, the Per Unit Setup
wizard should be performed to update the display meter scaling parameters.
