Figure 5.53 V/f Pattern
Note: 1. The following condition must be true when setting up the V/f pattern: E1-09 ≤ E1-07 < E1-06 ≤ E1-11 ≤ E1-04
2. To make the V/f pattern a straight line below E1-06, set E1-09 equal to E1-07. In this case the E1-08 setting is disregarded.
3. E1-03 is unaffected when the drive is initialized, but E1-04 through E1-13 return to their default values.
4. Only use E1-11, E1-12, and E1-13 to fine-tune the V/f pattern in the constant output range. These parameters rarely need to be changed.

E2: Motor 1 Parameters
These parameters contain the motor data needed for motor 1. Performing Auto-Tuning (including Rotational Auto-Tuning
and Stationary Auto-Tuning 2 and 3, and Rotational Auto-Tuning for V/f Control) automatically sets these parameters. Refer
to Auto-Tuning Fault Detection on page 397 for details if Auto-Tuning cannot be performed.
Note:
The function for switching between two motors cannot be used with a PM motor. E2-oo parameters are hidden when a PM motor control
mode is selected (A1-02 = 5, 6, or 7).
n
E2-01: Motor Rated Current
Provides motor control, protects the motor, and calculates torque limits. Set E2-01 to the full load amps (FLA) stamped on
the motor nameplate. If Auto-Tuning completes successfully, the value entered to T1-04 will automatically be saved to E2-01.

<1> Display is in the following units:
2o0028, 2o0042, and 4o0011 to 4o0027: 0.01 A units
2o0054 to 2o0248 and 4o0034 to 4o0930: 0.1 A units
Note:
Setting E2-01 ≤ E2-03 will trigger an oPE02 error. Set E2-03 correctly to prevent this error.
n
E2-02: Motor Rated Slip
Sets the motor rated slip in Hz to provide motor control, protect the motor, and calculate torque limits. This value is
automatically set during Auto-Tuning (Rotational Auto-Tuning, Stationary Auto-Tuning 2, 3).
No. Parameter Name Setting Range Default
E2-02 Motor Rated Slip 0.00 to 20.00 Hz
Determined by
C6-01 and o2-04
If Auto-Tuning cannot be performed, calculate the motor rated slip using the information written on the motor nameplate and
the formula below:
E2-02 = f - (n × 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 the no-load current for the motor in amperes when operating at the rated frequency and the no-load voltage. The drive sets
E2-03 during the Auto-Tuning process (Rotational Auto-Tuning and Stationary Auto-Tuning 2, 3). The motor no-load current
listed in the motor test report can also be entered to E2-03 manually. Contact the motor manufacturer to receive a copy of the
motor test report.
