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.

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.

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.

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.

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.
