11.6 E: Motor Parameters

◆ 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 11.48 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.

Motor 2 Control Mode
Selection
Sets the control method for motor 2.

(0 - 3)
Note:
• Changing the motor 2 control mode selection changes the settings value of parameters dependent on E3-01 to the 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.
