E2-03 Motor No-Load Current
0 to [E2-01]
(unit: 0.01 A)
Depending on
o2-04
Note: The resolution of E2-03 depends on the rated output power of the drive. If a drive is set up for 7.5 kW rated output power (ND or HD
rating) the value will have two decimal places. It will have one decimal place if a drive is set up for 11 kW and higher.
n
E2-04: Number of Motor Poles
Set the number of motor poles to E2-04. This value must be entered during Auto-Tuning, and will automatically be saved
to E2-04 if Auto-Tuning completes successfully.
No. Parameter Name Setting Range Default
E2-04 Number of Motor Poles 2 to 48 poles 4 poles
n
E2-05: Motor Line-to-Line Resistance
Sets the line-to-line resistance of the motor stator winding. If the Auto-Tuning completes successfully, this value is
automatically calculated. Remember this value must be entered as line-line and not line-neutral.
No. Parameter Name Setting Range Default
E2-05 Motor Line-to-Line Resistance 0.000 to 65.000 Ω
Depending on
o2-04
Note:
The setting range becomes 0.00 to 130.00 when using VZA0P2 and smaller.
If Auto-Tuning is not possible, then contact the motor manufacturer to find out the line-to-line resistance or measure it
manually. When using the manufacturer Motor Test Report, calculate E2-05 by the formulas below.
• E-type insulation: Multiply 0.92 times the resistance value (Ω) listed on the Test Report at 75 °C
• B-type insulation: Multiply 0.92 times the resistance value (Ω) listed on the Test Report at 75 °C.
• F-type insulation: Multiply 0.87 times the resistance value (Ω) listed on the Test Report at 115 °C.
n
E2-06: Motor Leakage Inductance
Sets the voltage drop due to motor leakage inductance as a percentage of motor rated voltage.
No. Parameter Name Setting Range Default
E2-06 Motor Leakage Inductance 0.0 to 40.0%
Depending on
o2-04
n
E2-07: Motor Iron-Core Saturation Coefficient 1
This parameter sets the motor iron saturation coefficient at 50% of the magnetic flux. If Rotational Auto-Tuning completes
successfully, then this value is automatically calculated.
No. Parameter Name Setting Range Default
E2-07 Motor Iron-Core Saturation Coefficient 1 0.00 to 0.50 0.50
n
E2-08: Motor Iron-Core Saturation Coefficient 2
This parameter sets the motor iron saturation coefficient at 75% of the magnetic flux. If Rotational Auto-Tuning completes
successfully, then this value is automatically calculated.
No. Parameter Name Setting Range Default
E2-08 Motor Iron-Core Saturation Coefficient 2 E2-07 to 0.75 0.75
n
E2-09: Motor Mechanical Loss
This parameter sets to the motor mechanical loss as a percentage of motor rated power (kW) capacity.
No. Parameter Name Setting Range Default
E2-09 Motor Mechanical Loss 0.0 to 10.0% 0.0%
Adjust this setting in the following circumstances:
• When there is a large amount of torque loss due to motor bearing friction.
• When there is a large amount of torque loss in a fan or pump application.
The setting for the mechanical loss is added to the torque.
n
E2-10: Motor Iron Loss for Torque Compensation
This parameter sets the motor iron loss in watts.
No. Parameter Name Setting Range Default
E2-10 Motor Iron Loss for Torque Compensation 0 to 65535 W
