5.5 E: Motor ParametersYASKAWA ELECTRIC SIEP C710616 27C YASKAWA AC Drive A1000 Technical Manual 201Parameter Details5information is not listed on the motor nameplate, contact the motor manufacturer to find out the correct value for themotor leakage inductance.Setting the Motor Iron-Core Saturation Coefficient 1, 2E2-07 and E2-08 are set when Auto-Tuning is performed.Setting the Motor Mechanical LossThe drive only requires this information when using Closed Loop Vector Control. The drive compensates for the degreeof mechanical loss with torque compensation. Although E2-09 rarely needs to be changed, adjustment may benefit thefollowing 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.Setting the Motor Iron Loss for Torque CompensationThis value only needs to be set when using V/f Control. Enter this value in watts to E2-10. The drive uses this setting toimprove the precision of torque compensation.◆ E3: V/f Pattern for Motor 2These parameters set the V/f pattern used for motor 2. Refer to Setting 16: Motor 2 selection on page 219 for details onswitching motors.Note: As the function for switching between two motors cannot be used with a PM motor, the E3- parameters will be hidden whena PM motor control mode is selected (A1-02 = 5, 6, or 7).■ E3-01: Motor 2 Control Mode SelectionSelects the control mode for motor 2. A control mode for PM motors cannot be selected for motor 2.Setting 0: V/f ControlSetting 1: V/f Control with PGSetting 2: Open Loop Vector ControlSetting 3: Closed Loop Vector ControlNote: Protection from motor overload (oL1) is determined by L1-01, just as it is for motor 1.■ E3-04 to E3-13Parameters E3-04 through E3-13 set up the V/f pattern used for motor 2 as shown in Figure 5.54.Note: Certain E3- parameters might not be visible depending on the control mode. Refer to Parameter Table on page 400.No. Parameter Name Setting Range DefaultE3-01 Motor 2 Control Mode Selection 0 to 3 0No.<1> Values shown here are for 200 V class drives. Double the value when using a 400 V class drive.<2> Default setting is determined by the control mode selected for motor 2 (E3-01).<3> The drive sets this value when Auto-Tuning is performed (Rotational Auto-Tuning and Stationary Auto-Tuning 1, 2).<4> Parameter ignored when E3-11 and E3-12 are set to 0.0.Parameter Name Setting Range DefaultE3-04 Motor 2 Max Output Frequency 40.0 to 400.0 Hz <2>E3-05 Motor 2 Max Voltage 0.0 to 255.0 <1> <1> <2>E3-06 Motor 2 Base Frequency 0.0 to [E3-04] <2>E3-07 Motor 2 Mid Output Frequency 0.0 to [E3-04] <2>E3-08 Motor 2 Mid Output Frequency Voltage 0.0 to 255.0 <1> <1> <2>E3-09 Motor 2 Minimum Output Frequency 0.0 to [E3-04] <2>E3-10 Motor 2 Minimum Output Frequency Voltage 0.0 to 255.0 <1> <1> <2>E3-11 Motor 2 Mid Output Frequency 2 0.0 to [E3-04] 0.0 Hz <4>E3-12 Motor 2 Mid Output Frequency Voltage 2 0.0 to 255.0 <1> 0.0 V <1> <3> <4>E3-13 Motor 2 Base Voltage 0.0 to 255.0 <1> 0.0 V <1> <3>
