E4-12: Motor 2 Iron-Core Saturation Coefficient 3
Set to the motor iron saturation coefficient at 130% of magnetic flux. This value is automatically set during Rotational Auto-Tuning.

E4-14: Motor 2 Slip Compensation Gain
Matches the slip compensation gain for motor 1 set to C3-01. Used to increase motor speed to account for motor slip by boosting the output frequency.
No. Parameter Name Setting Range Default
E4-14 Motor 2 Slip Compensation Gain 0.0 to 2.50 Determined by E3-01
Note: The control mode determines the default setting. The value shown here is for V/f Control.
This setting rarely needs to be changed, but adjustment may help under the following conditions:
• Increase this setting if the motor speed is below the desired value.
• Decrease this setting if the motor rotates faster than the desire speed.
n
E4-15: Motor 2 Torque Compensation Gain
Matches the torque compensation gain for motor 1 set to C4-01. This function magnifies the torque compensation to increase output torque.
No. Parameter Name Setting Range Default
E4-15 Motor 2 Torque Compensation Gain 0.0 to 2.50 1.00
Note: Adjust this parameter so the output current does not exceed the drive rated output currren when operating at low speeds.
• Increase the setting when using a long motor cable.
• When using a motor with a smaller capacity than the drive, increase this setting.
• If the motor begins to vibrate, adjust the value set so that the output current doesn’t exceed the drive rated output current when operating at low speeds.

E5-01: PM Motor Code Selection
Set the motor code appropriate for the PM motor being used. Depending on the motor code entered, the drive may be able to automatically set several
motor parameters.

E5-01 PM Motor Code Selection 0000 to FFFF Determined by o2-04
Note: This parameter is not reset when the drive is initialized using parameter A1-03. Depending on the motor code, the drive may be able to automatically set several motor parameters.
The default setting is for a Yaskawa pico motor with a speed rating of 1800 r/min. Set to “FFFF” when using a specialized or custom motor.
Detailed Description
According to the motor code, the value set for the maximum output frequency becomes the upper limit. Because changing E5-01 will reset all motor
parameters according to the new motor code, refrain from making frequent changes to E5-01
Note: Set to “FFFF” when using a specialized or custom motor.
