5.5 E: Motor Parameters
YASKAWA ELECTRIC SIEP C710616 27G YASKAWA AC Drive A1000 Technical Manual 221
E4-02: Motor 2 Rated Slip
This parameter sets the motor 2 rated slip frequency. Slip compensation is based on this value. The drive calculates this
value automatically during Auto-Tuning (Rotational Auto-Tuning and Stationary Auto-Tuning 1, 2).
For information on calculating the motor
rated slip, refer to E2-02: Motor Rated Slip on page 217.
E4-03: Motor 2 Rated No-Load Current
Set the no-load current for motor 2 in amperes when operating at the rated frequency and the no-load voltage. The drive
sets E2-03 during the Auto-Tuning process (Rotational Auto-Tuning and Stationary Auto-Tuning 1, 2). The motor
no-load current listed in the motor test report can also be entered to E2-03 manually. Contact the motor manufacturer to
receive a copy of the motor test report.
Note: Display is in the following units.
CIMR-A2A0004 to 2A0040, CIMR-A4A0002 to 4A0023: 0.01 A units
CIMR-A2A0056 to 2A0312, CIMR-A4A0031 to 4A0675: 0.1 A units
CIMR-A4A0930 to 4A1200: 1 A units
E4-04: Motor 2 Motor Poles
Set the pole number of motor 2 to E4-04. If Auto-Tuning completes successfully, the entered value to T1-06 will be
automatically saved to E4-04.
E4-05: Motor 2 Line-to-Line Resistance
Sets the line-to-line resistance for the motor 2 stator winding. If Auto-Tuning completes successfully, this value is
automatically calculated. Remember this value must be entered as line-to-line and not for each motor phase. Refer to
E2-05: Motor Line-to-Line Resistance on page 217 to manually enter this parameter setting.
E4-06: Motor 2 Leakage Inductance
Sets the voltage drop due to motor leakage inductance as a percentage of rated voltage of motor 2. This value is
automatically set during Auto-Tuning (Rotational Auto-Tuning and Stationary Auto-Tuning 1, 2).
E4-07: Motor 2 Motor Iron-Core Saturation Coefficient 1
Sets the motor 2 iron saturation coefficient at 50% of magnetic flux. This value is automatically set during Rotational
Auto-Tuning. Adjust this parameter when operating in the constant output range.
