Figure 4.16 V/f Pattern
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.
u Motor Parameters: E2-01 to E2-03
n Setting Motor Parameters
The following table provides instructions on how to set motor parameters. Refer to the motor
data sheet for the correct motor data.
No. Parameter Name Setting Method
E2-01 Motor Rated Current Sets the motor nameplate full load current in amperes (A).
E2-02 Motor Rated Slip
Calculate and set the motor rated slip based on the rated speed described on the
motor nameplate.
Motor rated slip = Motor rated frequency [Hz] - Rated speed [r/min] x No. of
motor poles / 120.
