3PH AC Induction Motor Initial Settings

Clicking "Ok" after selecting the 3PH AC Induction Motor option opens the "3PH AC Induction Motor" dia-
log box (see Figure 4., page
soidal waveforms are set.
There are 7 groups of initial settings that are specified by the user:
a. Pole Pairs - the number of Pole (North/South) Pairs in the motor
b. Speed Regulation - the manner in which to run the motor, either Open Loop (without speed regulation)
or Closed Loop (with speed regulation)
c. Speed Sensor
– Tachometer Pulses per Revolution - the number of pulses per revolution (of the speed sensor)
d. Stator Frequency/Mechanical Speed
– Minimum Stator Frequency/Minimum Mechanical speed - sets the minimum stator frequency in
Hz for open loop mode or minimum mechanical speed for closed loop mode
– Maximum Stator Frequency/Maximum Mechanical speed - sets the maximum stator frequency in
Hz for open loop mode or maximum mechanical speed for closed loop mode
e. V/F (Voltage vs. Frequency) Curve
– Min Voltage - sets the voltage level (expressed as a part of the 255th of the bus voltage) in the
first corner of the V/F curve
– Low Frequency - sets the frequency of the first corner of the V/F curve in Hz
– High Frequency - sets the frequency of the second corner of the V/F curve in Hz
f. Start-up Settings
– Voltage Slew Rate - affects the slew rate of the voltage during the motor start-up phase before
reaching the potentiometer set value
– Start-up Stator Frequency - sets the stator frequency during the start-up sequence
– Max Duration - sets the duration of the start-up sequence in milliseconds (ms)
– Min Rotor Frequency to Validate Closed Loop - sets the rotor speed or frequency to validate the
Closed Loop mode
g. Regulator Settings
– Integral Coefficient (Ki) - sets the value of the Integral Coefficient (Ki) of the Proportional
Integrative (PI) regulator
– Proporational Coefficient (Kp) - sets the value of the Proportional Coefficient (Kp) of the PI
regulator
– Sampling Time - sets the regulator sampling frequency in milliseconds (ms)
h. The "Change Motor Type" button enables the user to change the motor type(see
i. The "Advanced Settings..." button enables the user to set the Advanced Parameters (see
duction Motor Advanced Settings, page
j. The "Generate Source Files" button enables the user to generate the GUI configuration .h file. A
"Save" dialog window will appear, where the user can select in which folder to create the file as well
as the "Source" directory in the software library path (see
Libraries, page 16).
