No. Parameter Name Setting Range Default
E1-11 Middle Output Frequency 2 0.0 to [E1-04] 0.0 Hz <6>
E1-12 Middle Output Frequency Voltage 2 0.0 to 255.0 V <4> 0.0 V <5> <6>
E1-13 Base Voltage 0.0 to 255.0 V <4> 0.0 V <5> <7>
<4> Values shown are specific to 200 V class drives. Double the value for 400 V class drives. Multiply the value by 2.875 for 600 V class drives.
<5> The drive changes these settings when Auto-Tuning is performed (Rotational Auto-Tuning, Stationary Auto-Tuning 1, 2).
<6> Parameter ignored when E1-11 and E1-12 are set to 0.0.
<7> E1-13 and E1-05 are set to the same value when Auto-Tuning is performed.

Figure 5.35 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.
u 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 1 and 2) automatically sets these parameters. Refer to Auto-Tuning Fault Detection on page
321 for details if Auto-Tuning cannot be performed.
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:
2A0004 to 2A0040, 4A0002 to 4A0023, and 5A0007 to 5A0017: 0.01 A units.
2A0056 to 2A0415, 4A0031 to 4A0675, and 5A0022 to 5A0242: 0.1 A units.
4A0930 and 4A1200: 1 A units.
Note: An oPE02 error will occur if the motor rated current in E2-01 is set lower than the motor no-load current in E2-03. 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 1 and 2).
No. Parameter Name Setting Range Default
E2-02 Motor Rated Slip 0.00 to 20.00 Hz
Determined by
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)
