Expert
Adjust this parameter in these conditions. The drive adds the configured mechanical loss to the torque reference
value 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 Loss
No.
Name
(Hex.)
E2-10 Motor Iron Loss
(0317)
■
E2-11: Motor Rated Power (kW)
No.
Name
(Hex.)
E2-11 Motor Rated Power (kW)
(0318)
The drive automatically sets this parameter to the value input for "Motor Rated Power" during Auto-Tuning.

E3: V/F PARAMETER MOTOR 2

E3 parameters 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 [M2 Max
Out Frequency] to E3-10 [M2 Min Out Voltage] to manually set the V/f pattern.
■
Notes on Manually Setting V/f Patterns
• To configure a linear V/f pattern at frequencies lower than E3-06 [M2 Base Frequency], set E3-07 = E3-09 [M2
Mid A Frequency = M2 Min Out Frequency]. In this application, the drive ignores E1-08 [M2 Mid A Voltage].
• Set the five frequencies as specified by these rules:
E3-09 ≤ E3-07 < E3-06 ≤ E3-11 ≤ E3-04 [M2 Min Out Frequency ≤ M2 Mid A Frequency < M2 Base
Frequency ≤ M2 Mid B Frequency ≤ M2 Max Out Frequency]
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.
• When you use A1-03 [Init Parameters] to initialize the drive, the drive will reset the manually set values for E3-
04 to E3-13 [M2 Base Voltage] to default values.

V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the mechanical loss of the motor. It is set as a percentage of E2-11 [Motor Rated Power
(kW)]. Usually it is not necessary to change this setting.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the motor iron loss.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the motor rated output in the units from o1-58 [Mot Capacity Unit].
