Motor Control Tuneup: Measurements
When selecting all the measurements the VCO’s will be calibrated and for both
phase combinations, AB and BC, the measurements of Tau, R1, R2 inner, R2 outer,
Lsigma starting, Lsigma outer, Lsigma curve, Bridge flux and the Flux saturation
curve will be performed. These measurements will be checked for balance between
phase combinations and monotonically increasing curves. If these checks are passed
the results will be averaged and the motor control rules will calculate new tune-up
values.
Each measurement can be selected separately along with which phase combinations
to use and whether new tune-up values are calculated.
• Use phase A-B in measurements
• Use phase B-C in measurements
• Calibrate VCO offsets before making measurements
• Measure R1, stator resistance
• Measure R2, outer rotor resistance
• Measure Lsigma, leakage inductance (starting, outer & curve)
along with inner rotor resistance and bridge flux
• Measure flux saturation curve
• Calculate new motor control tune-up values
• Skip phase balance check
Clearing measured elementals will calculate new tune-up values based on the
original motor data.
Motor Control Tuneup: Operation
This will perform the requested measurements of the previous screen and a dialog
box will appear to show the progress.
Use of the Abort function will cancel the measurements and throw present results
away.
Panel Meter Setup
The Panel Meter Setup wizard directs configuration of the panel meters. For more
information on the panel meters, see the Analog Inputs/Outputs and Mapping
function help.
Per Unit Setup
The Per Unit Setup wizard directs configuration of the per unit parameters that
determine scaling for the DDI. It is recommended that the control be allowed to
calculate the default per unit settings.
