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.
