Polarity Detection Current

Sets the current that the drive uses to estimate the initial motor magnetic pole as a percentage where E5-03 [PM Motor Rated Current (FLA)] = 100%.

100%

(0 - 150%)

When you use a Yaskawa motor, check the motor nameplate for an “Si” value and set this parameter ≥ "Si × 2". Consult the motor manufacturer for information about maximum setting values.

Find the Polarity of Magnetic Poles

When you start operation, the drive estimates the magnetic poles and finds the polarity of the magnetic poles.

Use U6-57 [PolePolarityDeterVal] to make sure that the magnetic pole estimate was correct.

When you do High Frequency Injection Auto-Tuning, the drive automatically sets n8-84.
