YASKAWA TOEPYAIGA5002A GA500 DRIVE PROGRAMMING 425
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.

■ n8-88: Vout Limit Switching Level
No.
(Hex.)
Name Description
Default
(Range)
n8-88
(02BD)
Vout Limit Switching Level
Sets the current level at which output voltage limit sequence selection occurs as a percentage where
the motor rated current is 100%. Normally there is no need to change this setting.

Name Description
Default
(Range)
n8-89
(02BE)
Vout Limit Switching
Hysteresis
Sets the hysteresis width of the current level at which output voltage limit sequence selection occurs
as a percentage where the motor rated current is 100%. Normally there is no need to change this
setting.

■ 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.
