n8-79: Pull-in Current @ Deceleration
No.
(Hex.)
Name
Description
Default
(Range)
n8-79
(05FE)
Pull-in Current @
Deceleration
Sets the pull-in current that can flow during deceleration as a percentage of the
E5-03 [PM Motor
Rated Current (FLA)]
.
50%
(0 - 200%)
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
No.
(Hex.)

Description
Default
(Range)
n8-84
(02D3)
Expert
Polarity Detection Current
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.
100%
(0 - 150%)
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.

n8-91: Id Limit at Voltage Saturation
No.
(Hex.)
Name
Description
Default
(Range)
n8-91
(02F7)
Id Limit at Voltage
Saturation
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.
