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 1. 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.
