29 / 53 page ![]() UM0432 Motor control operations 29/53 7.4.6 ”3-phase PMAC motor (sinewave)" settings Figure 16. "3-phase PMAC motor (sinewave)" basic parameters window Table 10. "3-phase PMAC motor (sinewave)" basic parameters Parameter name Description Poles pairs Number of pole (north/south) pairs in the motor. Speed regulation Manner in which to run the motor, either open loop (without speed regulation) or closed loop (with speed regulation). Sensor configuration Number of hall sensors on the motor: one, two or three sensors. Synchronous speed Min Sets the target minimum stator frequency in Hz for closed-loop mode. Max Sets the target maximum stator frequency in Hz for closed-loop mode. V/F (voltage vs. frequency) curve limitation 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. 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 (only in open loop). |
