If Auto-Tuning cannot be performed, use the information shown on the motor nameplate to
calculate the motor rated slip by the following formula.
d2-01=f-(n‧p)/120
f ∶rated frequency (Hz), n ∶ motor rated speed ( min-1), p ∶ number of motor poles
d2- 02 Motor No-Load Current
Sets the motor no-load current when running at no-load voltage and rated frequency. This will
be set automatically during Auto-Tuning. This can also be set according to the no-load current
listed on the motor test report. Contact the motor manufacturer for a test report.
0.0 A to [d2-00] A
( exclude d2-00)
d2- 03 Number of Motor Poles
Sets the number of motor poles. This will be set automatically during Auto-Tuning.
d2- 04 Motor Line-to-Line Resistance
Sets the line-to-line resistance. This will be set automatically during Auto-Tuning.
If Auto-Tuning cannot be performed, contact the motor manufacturer for the test report. Use
the line-to-line resistance listed in the rest report to calculate the line-to-line resistance by the
following formula.
· E-type insulation: the resistance value (Ω) listed on the test report at 75°C × 0.92
· B-type insulation: the resistance value (Ω) listed on the test report at 75°C × 0.92
· F-type insulation: the resistance value (Ω) listed on the test report at 115°C × 0.87
Motor Line-to-Line Resistance
■ d2- 05 Motor Leakage Inductance
Sets the voltage drop caused by the motor leakage inductance relative to the motor rated
frequency and current. This will be set automatically during Auto-Tuning.
