E5: Pm Motor Settings - YASKAWA U1000 Series Technical Manual

5.5 E: Motor Parameters
E4-08: Motor 2 Motor Iron-Core Saturation Coefficient 2
■
Sets the motor iron saturation coefficient at 75% of magnetic flux. This value is automatically set during Rotational
Auto-Tuning. Adjust this parameter when operating in the constant output range.
No.
E4-08
■ E4-09: Motor 2 Mechanical Loss
There is normally no need to change this parameter from the default value.
Sets the motor mechanical loss as a percentage of motor rated power (kW).
This parameter may need to be adjusted 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.
No.
E4-09
E4-10: Motor 2 Iron Loss
■
Sets the motor 2 iron loss in watts.
No.
E4-10
E4-11: Motor 2 Rated Power
■
Sets the motor 2 rated power. If Auto-Tuning completes successfully, the value entered to T1-02 will automatically be
saved to E4-11.
No.
E4-11

◆ E5: PM Motor Settings

These parameters set the motor data of a PM motor.
When Yaskawa motors are used, entering the motor code written on the motor nameplate will set up the E5-
parameters.
For all other PM motors, Auto-Tuning can be performed. If motor data is known, it can also be entered manually.
Note: 1. E5- parameters are visible only when a PM motor control mode is selected (A1-02 = 5, 6, or 7).
2. E5- parameters are not reset when the drive is initialized using parameter A1-03.
■ E5-01: Motor Code Selection (for PM Motors)
When Yaskawa motors are used, set the motor code for the PM motor being used. Depending on the motor code entered,
the drive automatically sets several parameters to appropriate values.
Code Selection (for PM Motors) on page 543
Setting parameter E5-01 to FFFF will allow to set the motor data manually using the E5- parameters.
No.
