Calculated control variables
The Innovation Series dr ive contains a set of variables th at are calculated from the
primary motor parameters but are not exact reflections of the primary parameters.
These calculated var iables are used in motor control and protective functions. The
values of the variables are calculated at drive in itialization after power up or a hard
reset.
The following table li sts the variables calculated fr om the primary value parameter s:
Parameter Description
100% Motor torque Motor torque at motor nameplat e conditions. New ton-
meters or Pound-feet
100% Flux Motor flux at motor nameplate conditions. Volts/hertz
100% Torque current Motor torque current at motor nameplate condi tions.
RMS amps
100% Flux current Motor flux current at motor nameplate conditions.
RMS amps
100% Slip Motor slip at motor nam eplate conditi ons.
Radians/second
Display meter scaling parameters
The Innovation Series dr ive contains a set of parameter s that specify the scaling for
the DDI and toolbox displ ay meters. These parameters are ca lculated 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 wizar d, the Per Unit Setup
wizard should be performed to update the display meter scaling parameters.
