E3: V/F Pattern For Motor 2 - YASKAWA A1000 HHP Programming Manual

1.5 E: Motor Parameters
Set the Motor Mechanical Loss
Only required in Closed Loop Vector Control. The drive compensates for the degree of mechanical loss with torque
compensation. Although E2-09 rarely needs to be changed, adjustment may be necessary 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.
Set the Motor Iron Loss for Torque Compensation
Only required when using V/f Control. Enter this value in watts to E2-10. The drive uses this setting to improve the precision
of torque compensation.

switching motors.
Note: The function for switching between two motors cannot be used with a PM motor. E3-oo parameters are hidden when a PM motor control
mode is selected (A1-02 = 5, 6, or 7).
n E3-01: Motor 2 Control Mode Selection
Selects the control mode for motor 2. A control mode for PM motors cannot be selected for motor 2.
No.
E3-01
Note: L1-01 determines protection from motor overload (oL1) in motor 2 and motor 1.
Setting 0: V/f Control
Setting 1: V/f Control with PG
Setting 2: Open Loop Vector Control
Setting 3: Closed Loop Vector Control
n E3-04 to E3-13
Parameters E3-04 through E3-13 set up the V/f pattern used for motor 2 as shown in
Note: Certain E3-oo parameters might not be visible depending on the control mode.
