12.6 E: Motor Parameters566 YASKAWA SIEPC71061753A GA500 Technical ManualThe drive uses this coefficient when it operates with constant output. The drive uses this coefficient when itoperates the motor in the constant output range.■ E2-09: Motor Mechanical LossNo.(Hex.) Name Description Default(Range)E2-09(0316)ExpertMotor Mechanical LossSets the mechanical loss of the motor. It is set as a percentage of E2-11 [Motor Rated Power].Usually it is not necessary to change this setting.0.0%(0.0 - 10.0%)Adjust this parameter in these conditions. The drive adds the configured mechanical loss to the torque referencevalue as a torque compensation value:• There is a large quantity of torque loss from motor bearing friction.• There is a large quantity of torque loss in fans and pumps.■ E2-10: Motor Iron LossNo.(Hex.) Name Description Default(Range)E2-10(0317)Motor Iron LossSets the motor iron loss.Determined by o2-04, C6-01(0 - 65535 W)■ E2-11: Motor Rated PowerNo.(Hex.) Name Description Default(Range)E2-11(0318)Motor Rated PowerSets the motor rated output in the units from o1-58 [Motor Power Unit Selection].Determined by o2-04, C6-01(0.00 - 650.00 kW)The drive automatically sets this parameter to the value input for “Motor Rated Power” during Auto-Tuning.◆ E3: V/f Pattern for Motor 2E3 parameters [V/f Pattern for Motor 2] set the control mode and V/f pattern used for motor 2.Note:V/f preset patterns equivalent to those set with E1-03 [V/f Pattern Selection] are not available for E3 parameters. Use E3-04 [Motor 2Maximum Output Frequency] to E3-10 [Motor 2 Minimum Output Voltage] to manually set the V/f pattern.■ Notes on Manually Setting V/f PatternsFigure 12.61 Motor 2 V/f Pattern Diagram• To configure a linear V/f pattern at frequencies lower than E3-06 [Motor 2 Base Frequency], set E3-07 = E3-09[Motor 2 Mid Point A Frequency = Motor 2 Minimum Output Frequency]. In this application, the drive ignoresE1-08 [Mid Point A Voltage].• Set the five frequencies as specified by these rules:E3-09 ≤ E3-07 < E3-06 ≤ E3-11 ≤ E3-04 [Motor 2 Minimum Output Frequency ≤ Motor 2 Mid Point AFrequency < Motor 2 Base Frequency ≤ Motor 2 Mid Point B Frequency ≤ Motor 2 Maximum OutputFrequency]Incorrect settings will trigger oPE10 [V/f Data Setting Error].• If E3-11 = 0.0 Hz, the drive will ignore the V/f pattern settings.V/f OLV OLV/PMOLV/PM AOLV/PM EZOLVV/f OLV OLV/PMOLV/PM AOLV/PM EZOLVV/f OLV OLV/PMOLV/PM AOLV/PM EZOLV
