Figure 5.13 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.

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. Parameter Name Setting Range Default
E2-01 Motor Rated Current
10% to 200% of the drive
rated current.
(unit: 0.01 A)

o2-04
n E2-02: Motor Rated Slip
Sets the motor rated slip in Hz.
No. Parameter Name Setting Range Default
E2-02 Motor Rated Slip 0.00 to 20.00 Hz
Depending on
o2-04
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.
No. Parameter Name Setting Range Default
E2-03 Motor No-Load Current
0 to [E2-01]
(unit: 0.01 A)
Depending on
o2-04
n E2-05: Motor Line-to-Line Resistance
Sets the line-to-line resistance of the motor stator winding. Remember this value must be entered as line-line and not line-
neutral.
