Note:
The change is linear between n8-75 [Medium Load Iq Level (low)] and n8-77 and the level of the pull-in current from n8-78 [Medium
Load Id Current] to n8-49 [Heavy Load Id Current].

If overcurrent occurs during deceleration, slowly decrease the setting in 5% increments.
Note:
When n8-79 = 0, the drive will use the value set in n8-51 [Pull-in Current @ Acceleration].

n8-84 Polarity Detection Current
(02D3)
Expert
WARNING! Sudden Movement Hazard. Make sure that the polarity is correct before you send a Run command. If the drive
incorrectly detects the polarity, the drive can rotate in the direction opposite of the Run command and cause serious injury or
death.
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.

V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the filter time constant for the d-axis current reference. Usually it is not necessary to change
this setting.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Set n8-49 [Heavy Load Id Current] to the percentage of load current (q-axis current) that you will
apply, where E5-03 [Motor Rated Current (FLA)] = a setting value of 100%.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the level of the pull-in current as a percentage, where E5-03 [PM Motor Rated Current
(FLA)] = 100%.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the pull-in current that can flow during deceleration as a percentage of the E5-03 [PM Motor
Rated Current (FLA)].
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
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%.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the method of output voltage limit. If there is vibration in the constant output range, set
Feedforward Method. Usually it is not necessary to change this setting.
