12.5 E: MOTOR
628 SIEPYEUOQ2A01A AC Drive Q2A Technical Manual
Auto-Tuning automatically sets this parameter to the value of [Number of Motor Poles].
■ E9-09 Motor Rated Slip
No.
(Hex.)
Name Description
Default
(Range)
E9-09
(11EC)
Motor Rated Slip
Sets the motor rated slip.
0.0 Hz
(0.0 - 20.0 Hz)
The setting value of this parameter is the slip compensation reference value.
The drive uses the setting values of E9-03, E9-04, and E9-08 to calculate this parameter. When Motor Rated Slip
= 0, Auto-Tuning automatically sets this parameter to the value of [Motor Rated Slip].
Note:
Set E9-01 = 0 [Motor Type Selection = IM (Induction)] before you set this parameter.
■ E9-10 Motor L-L Resistance
No.
(Hex.)
Name Description
Default
(Range)
E9-10
(11ED)
Motor L-L Resistance
Sets the line-to-line resistance for the motor stator windings.
Determined by o2-04
(0.000 - 65.000 Ω)
Note:
This value is the motor line-to-line resistance. Do not set this parameter with the single-phase resistance.
Stationary Auto-Tuning automatically sets this parameter. If you cannot do Stationary Auto-Tuning, use the test
report from the motor manufacturer. You can calculate the motor line-to-line resistance with one of these
formulas:
• E-type insulation: [the resistance value (Ω) shown on the test report at 75 °C] × 0.92
• 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
