4-265
IPM Estimator Compensation (22-35)
When the estimator mode (22-26) setting is 1, adjust the estimator compensation will change the output
voltage. Adjustments can be made according to the following situation:
When the output voltage (12-19) is too low (Note 1), the compensation setting value must be set higher.
When the MPTA function (22-32) is at 1, and the output voltage is still too high (Note 2), adjust to a lower
compensation setting value.
When the MPTA function (22-32) is at 2, and the output voltage is still too high, then increase the
flux-weakening restrict (22-18) parameter setting value.
Note 1: When the permanent magnet motor is operating at no load frequency conditions, the output
voltage should be greater than or equal to the motor back EMF coefficient stated on the nameplate.
Note 2: When the permanent magnet motor is operating at full load frequency conditions, the output
voltage should be lesser than or equal to the motor’s rated voltage stated on the nameplate.
