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 Mot 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 in the following situations.
•
If the load is large and motor rotation is not stable, decrease the setting value.
•
When you change
E5: PM MOTOR SETTINGS
, set
n8-49 = 0
, then adjust this parameter.

Medium Load Iq Level
(High)
Sets the load current level at which heavy load control starts where
E5-03 [PM Mot Rated Current
(FLA)]
is 100%. Usually it is not necessary to change this setting.

Ac/Dec Pull-In Current
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 = EZ Vector]
, this parameter will always be in effect for speed ranges less than
n7-10 [Pull-in
SwitchSpeed]
.

Volt-Err Compensation
Time
Sets the time constant that the drive uses when adjusting for voltage errors.
1.00 s
(0.00 - 10.00 s)
Adjust this parameter in these conditions:
•
If oscillation occurs at the time of start up, increase the setting value.
•
If hunting occurs when operating at low speed, increase the setting value.
•
If fast changes in the load cause hunting, increase the setting value in 0.1-unit increments. If you cannot stop
hunting, set
n8-51 [Ac/Dec Pull-In Current]
to 0% and set
n8-54
to 0.00 s, and disable compensation for voltage
errors.

Load Inertia
Sets the ratio between motor inertia and machine inertia.
1
(1 - 4)
Adjust in the following situations.
•
If torque and speed response is unsatisfactory, gradually increase the setting from 0.
•
If the motor does not run smoothly, gradually increase the setting from 0.
