PM eSave Coef.Kt
Sets torque linearity. This parameter uses the Kt value from the motor nameplate. Usually it is not
necessary to change this setting.
1.00
(0.00 - 3.00)
When
E5-01 = 1xxx [PM Mot Code Selection = Yaskawa SSR1 series IPM motor]
, the drive automatically
calculates the energy-saving coefficient Kt and uses that value to control operation.
Do this procedure to prevent oscillation when you set
b8-01 = 1 [eSave Ctrl Selection = Enabled]
.
1. Check
U5-22 [Energy Save Kt Coeff]
and make sure that it aligns with the Kt value on the motor nameplate.
2. If the numbers are different, set
b8-17
to the Kt value on the motor nameplate.

eSave Search Frequency
Sets the frequency of Energy-saving control search operations. Usually it is not necessary to
change this setting.
Determined by A1-02
(10 - 300 Hz)
Note:
•
If low inertia causes vibration in the machine, increase the setting value in 10 Hz increments and check the response. If
A1-02 = 8
[Control Method = EZ Vector]
, increase the setting value in 1 Hz increments.
•
To make the motor more efficient, decrease the setting value in 1 Hz increments until the point immediately before machine vibration
starts to occur.

PM eSave Width for Test
Sets the amplitude of Energy-saving control search operations.
1.0 degrees
(0.1 - 5.0 degrees)
An increase in the value can make the operational efficiency better. However, if the load inertia is small, it may be
necessary to adjust the value to prevent machine vibration.
Note:
•
If low inertia causes vibration in the machine, decrease the setting value in 1.0-degree increments and check the response.
•
To make the motor more efficient, increase the setting value in 1.0-degreee increments until the point immediately before machine
vibration starts to occur.

PM eSave Gain for Test
Sets the gain of Energy-saving control search operations.
0.3Hz
(0.1 - 20.0 Hz)
When you decrease the value of
C5-01 [ASR PGain 1]
, also decrease the value of
b8-21
to keep the correct ratio.
