<1> Values shown here are for 200 V class drives; double the values for 400 V class drives.
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.

E2: Motor 1 Parameters

These parameters contain the most important motor data needed for optimal motor control.
n E2-01: Motor Rated Current
Set E2-01 to the full load amps (FLA) stamped on the motor nameplate.
No.
E2-01
Note: Change E2-01 after changing the value set to E2-03. Setting E2-01 < E2-03 will trigger an oPE02 error.
n E2-02: Motor Rated Slip
Sets the motor rated slip in Hz.
No.
E2-02
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)
n E2-03: Motor No-Load Current
Set E2-03 to the motor no-load current at rated voltage and rated frequency. Contact the motor manufacturer for information
about the no-load current.
