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.

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.

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.

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.
