Parameter Details
1
Adjust this setting in the following circumstances:
• When torque loss is large due to motor bearing friction.
• When the torque loss in the load is large.
The setting for the mechanical loss is added to the torque.
■ E2-10: Motor Iron Loss for Torque Compensation
This parameter sets the motor iron loss in watts.
■ E2-11: Motor Rated Power
This parameter sets the motor rated power in kW. During Auto-Tuning the value must
entered to parameter T1-02. If Auto-Tuning completes successfully, the value entered will
automatically be saved to E2-11.
■ E2-12: Motor Iron-Core Saturation Coefficient 3
This parameter sets the motor iron saturation coefficient at 130% of the magnetic flux.
◆ E3: V/f Characteristics for Motor 2
These parameters set the V/f pattern used for motor 2. Refer to terminal functions, digital
inputs, Setting 16: Motor 2 Selection on page 148 for details on switching motors.
■ E3-01: Motor 2 Control Mode Selection
