■ E2-11: Motor Rated Power
No.
(Hex.)
Name Description
Default
(Range)
E2-11
(0318)
Motor Rated Power
Sets the motor rated output in the units from o1-58 [Motor Power Unit Selection].
Determined by o2-04, C6-01
(0.00 - 650.00)
The drive automatically sets this parameter to the value input for “Motor Rated Power” during Auto-Tuning.
◆ 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 2.53 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.
• When you use A1-03 [Initialize Parameters] to initialize the drive, the drive will reset the manually set values for
E3-04 to E3-13 [Motor 2 Base Voltage] to default values.
■ E3-01: Motor 2 Control Mode Selection
No.
(Hex.)
Name Description
Default
(Range)
E3-01
(0319)
Motor 2 Control Mode
Selection
Sets the control method for motor 2.
0
(0, 2)
Note:
• When you change this setting, the drive will set all parameters that are dependent on E3-01 to their default settings.
• Parameter L1-01 [Motor Overload (oL1) Protection] sets the protection operation of oL1 [Motor Overload] the same as Motor 1.
• When you use parameter A1-03 [Initialize Parameters] to initialize the drive, this parameter is not reset.
