The drive uses this coefficient when it operates with constant output. The drive uses this coefficient when it
operates the motor in the constant output range.

Motor Mechanical Loss
Sets 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 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.

E3: V/f Pattern for Motor 2
E3 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 2
Maximum Output Frequency] to E3-10 [Motor 2 Minimum Output Voltage] to manually set the V/f pattern.
■
Notes on Manually Setting V/f Patterns
Figure 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 ignores
E1-08 [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 A
Frequency < Motor 2 Base Frequency ≤ Motor 2 Mid Point B Frequency ≤ Motor 2 Maximum Output
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.
