Figure 4.22 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.
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.
No. Parameter Name Setting Range Default
E2-01 Motor Rated Current
10% to 200% of the drive
rated current
Determined by
o2-04
Note: 1. The number of decimal places in the parameter value depends on the drive model. This value has two decimal places (0.01 A) if the
drive is set for a maximum applicable motor capacity up to and including 11 kW, 2A0031, 4A0021 (input voltage of 460 V or higher)
or 4A0027 (input voltage of lower than 460 V) and one decimal place (0.1 A) if the maximum applicable motor capacity is higher than
11 kW, 2A0046, 4A0027 (input voltage 460 V or higher) or 4A0034 (input voltage lower than 460 V).
2. 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 E2-11: Motor Rated Power
Sets the motor rated power in kW. If Auto-Tuning completes successfully, the value entered to T1-02 will automatically be
saved to E2-11.
No. Parameter Name Setting Range Default
E2-11 Motor Rated Power 0.00 to 370.00 kW
Determined by
o2-04
n E5-02: Motor Rated Power
Sets the rated power of the motor. Determined by the value set to T2-04 during Stationary Auto-Tuning for PM motors.
No. Parameter Name Setting Range Default
E5-02 Motor Rated Power 0.10 to 370.00 kW
Determined by
o2-04
n E5-03: Motor Rated Current
Sets the motor rated current in amps. Automatically set when the value is entered to T2-06 during Auto-Tuning.
No. Parameter Name Setting Range Default
E5-03 Motor Rated Current
10 to 200% of drive rated
current
Determined by
o2-04
Note: The number of decimal places in the parameter value depends on the drive model. This value has two decimal places (0.01 A) if the drive
is set for a maximum applicable motor capacity up to and including 11 kW, and one decimal place (0.1 A) if the maximum applicable motor
capacity is higher than 11 kW.
