Figure 5.54 V/f Pattern for Motor 2
Note: 1. The following conditions must be true when setting up the V/f pattern: E3-09 ≤ E3-07 < E3-06 ≤ Ε3-11 ≤ E3-04
2. To make the V/f pattern a straight line at a frequency lower than E3-06, set E3-09 equal to E3-07. In this case, E3-08 is disregarded.
3. Parameters E3-04 through E3-13 are reset to their default values when the drive is initialized.
4. Only use E3-11, E3-12, and E3-13 to fine-tune the V/f pattern in the constant output range. These parameters rarely need to be changed.
u
E4: Motor 2 Parameters
E4 parameters contain the motor data for motor 2. These parameters are usually set automatically during the Auto-Tuning
process for vector control modes (Rotational Auto-Tuning, Stationary Auto-Tuning 2, 3). 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. E4-oo parameters are hidden when a PM motor control
mode is selected (A1-02 = 5, 6, or 7).
n
E4-01: Motor 2 Rated Current
Protects the motor and calculates torque limits. Set E4-01 to the full load amps (FLA) stamped on the nameplate of motor 2.
If Auto-Tuning completes successfully, the value entered to T1-04 will automatically be saved to E4-01.

2o0054 to 2o0248 and 4o0034 to 4o0930: 0.1 A units
Note: An oPE02 error will occur if the motor rated current in E4-01 is set lower than the motor no-load current in E4-03. Set E4-03 correctly to
prevent this error.
n
E4-02: Motor 2 Rated Slip
Sets the motor 2 rated slip frequency and is the basis for slip compensation value. The drive calculates this value automatically
during Auto-Tuning (Rotational Auto-Tuning and Stationary Auto-Tuning 2, 3).
Refer to E2-02: Motor Rated Slip on page 255 for information on calculating the motor rated slip.

n
E4-03: Motor 2 Rated No-Load Current
Sets the no-load current for motor 2 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 for a copy of the motor
test report.
