n8-79: Pull-in Current @ Deceleration
No.

n8-79 Pull-in Current @
Deceleration
(05FE)
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

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.
If you use a Yaskawa motor and the motor nameplate has an "Si" item, set this parameter to a value equal to or more
than "Si × 2". Consult the motor manufacturer for the maximum setting values.
Find the Polarity of Magnetic Poles
At start, the drive estimates the magnetic poles and finds the polarity of the magnetic poles.
Use U6-57 [PolePolarityDeterVal] to make sure that the drive correctly estimated the polarity of the magnetic poles.
The drive automatically calculates n8-84 when High Frequency Injection Auto-Tuning completes successfully.

YASKAWA TOEPYAIHV6002A HV600 Drive Programming
V/f OLV/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/PM EZOLV OLV/PM
Sets the current for processing an estimation of the initial motor magnetic pole as a percentage,
where E5-03 [PM Motor Rated Current] is the 100% value.
V/f OLV/PM EZOLV OLV/PM
Sets the limit value of feedback output voltage limit Id operation. Enabled when n8-87 = 0 [Output
Voltage Control Selection = Speed Feedback Form]. Usually it is not necessary to change this
setting.
