YASKAWA ELECTRIC SIEP C710617 05F YASKAWA AC Drive GA700 Technical Manual 813
• B-type insulation: the resistance value (Ω) shown on the test report at 75 °C × 0.92
• F-type insulation: the resistance value (Ω) shown on the test report at 115 °C × 0.87
■ E4-06: Motor 2 Leakage Inductance
No.
(Hex.)
Name Description
Default
(Range)
E4-06
(0326)
Motor 2 Leakage
Inductance
Sets the voltage drop from motor 2 leakage inductance as a percentage of
Motor Rated Voltage when motor 2 operates at the rated frequency and rated
current.
Determined by o2-04,
C6-01
(0.0 - 60.0%)
The drive sets this parameter during Rotational Auto-Tuning and Stationary Auto-Tuning.
Note:
You cannot usually find the quantity of voltage drop on the motor nameplate. If you do not know the value of the motor 2 leakage
inductance, get the test report from the motor manufacturer.
■ E4-07: Motor 2 Saturation Coefficient 1
No.
(Hex.)
Name Description
Default
(Range)
E4-07
(0343)
Motor 2 Saturation
Coefficient 1
Sets the motor 2 iron-core saturation coefficient at 50% of the magnetic
flux.
0.50
(0.00 - 0.50)
The drive sets this parameter during Rotational Auto-Tuning. The drive uses this coefficient when it operates with
constant output.
■ E4-08: Motor 2 Saturation Coefficient 2
No.
(Hex.)
Name Description
Default
(Range)
E4-08
(0344)
Motor 2 Saturation
Coefficient 2
Sets the motor 2 iron-core saturation coefficient at 75% of the magnetic
flux.
0.75
(E4-07 - 0.75)
The drive sets this parameter during Rotational Auto-Tuning. The drive uses this value to operate the motor at
constant output.
■ E4-09: Motor 2 Mechanical Loss
No.
(Hex.)
Name Description
Default
(Range)
E4-09
(033F)
Expert
Motor 2 Mechanical
Loss
Sets the mechanical loss of motor 2. Motor rated power (kW) is 100%.
Usually it is not necessary to change this setting.
0.0%
(0.0 - 10.0%)
Adjust this parameter in these conditions. The drive adds the configured mechanical loss to the torque reference
value as a torque compensation value:
• There is a large quantity of torque loss from motor bearing friction.
• There is a large quantity of torque loss in fans and pumps.
■ E4-10: Motor 2 Iron Loss
No.
(Hex.)
Name Description
Default
(Range)
E4-10
(0340)
Motor 2 Iron Loss
Sets the motor iron loss for motor 2.
Determined by o2-04
and C6-01
(0 - 65535 W)
