Figure 5.52 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 1 and 2) automatically sets these parameters. Manually enter the motor data into these parameters
when 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).

E2-01: Motor Rated Current
Used to protect the motor and calculate 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.

E2-01 Motor Rated Current
10% to 200% of the drive
rated current
Determined by
C6-01 and o2-04
Note: 1. The number of decimal places in the parameter value depends on the drive model and the ND/HD selection in parameter C6-01. 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. Refer to Power Ratings on page 373.
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
E2-02: Motor Rated Slip
Sets the motor rated slip in Hz to 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
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:
