n8-48
(053B)
Pull-in/Light Load Id
Current
On the basis that parameter
E5-03 [Motor Rated Current (FLA)]
is the 100% value, this parameter
sets the d-axis current that flows to the motor during run at constant speed as a percentage.
30%
(0 - 200%)
Adjust in the following situations.
•
Slightly reduce this value if there is too much current when driving a light load at a constant speed.
•
Increase the setting value in steps of 5% when hunting or vibration occurs during run at constant speed.
•
Increase the setting value in steps of 5% if the motor stalls during run at constant speed.

Description
Default

n8-49
(053C)
Heavy Load Id Current
Sets the d-axis current to that the drive will supply to the motor to run it at a constant speed with a
heavy load. Considers
E5-03 [PM Motor Rated Current (FLA)]
to be 100%. Usually it is not
necessary to change this setting.
Determined by E5-01
(-200.0 - +200.0%)
When you use an IPM motor, you can use the reluctance torque of the motor to make the motor more efficient and
help conserve energy.
When you operate an SPN motor, set this parameter to 0.
Adjust this parameter in these conditions:
•
If the load is large and motor rotation is not stable, decrease the setting value.
•
If you change the
E5 parameters [PM Motor Settings]
, set
n8-49 = 0
, then adjust this parameter.

Description
Default
(Range)
n8-50
(053D)
Medium Load Iq Level
(High)
Sets the load current level to start high efficiency control as a percentage of
E5-03 [PM Motor Rated
Current (FLA)]
. Usually it is not necessary to change this setting.

n8-51: Pull-in Current @ Acceleration
No.
(Hex.)
Name
Description
Default
(Range)
n8-51
(053E)
Pull-in Current @
Acceleration
Sets the pull-in current allowed to flow during acceleration/deceleration as a percentage of the motor
rated current.
Determined by A1-02
(0 - 200%)
Adjust in the following situations.
•
When the motor does not smoothly because of large loads, increase the setting value in 5% increments.
•
If too much current flows during acceleration, decrease the setting value.
Note:
When
A1-02 = 8 [Control Method Selection = EZOLV]
, this parameter will always be in effect for speed ranges less than
n7-10 [Pull-in
Current Switching Speed]
.
