Note: 1.
The following condition must be true when setting up the V/f pattern: E1-09 ≤ E1-07 ≤ E1-06 ≤ E1-04
2.
To make the V/f pattern a straight line set E1-09 = E1-07. In this case the E1-08 setting is disregarded.
3.
E1-03 is unaffected when the drive is initialized using parameter A1-03, but the settings for E1-04 through E1-10 are returned to their
default values.

Calculate the motor rated slip using the information written on the motor nameplate and the formula below:
E2-02 = f - (n x p)/120
(f: rated frequency (Hz), n: rated motor speed (r/min), p: number of motor poles)
