E2: Motor Parameters - YASKAWA L1000V Technical Manual

5.5 E: Motor Parameters
The availability of the following parameters depends on the control mode.
Figure 5.10
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 = E1-07. In this case the E1-08 setting is disregarded.
3. E1-03 is unaffected when the parameters are initialized using parameter A1-03, but the settings for E1-04 through E1-13 are returned
to their default values.
4. Parameters E1-11, E1-12, and E1-13 should only be used to fine-tune the V/f pattern in the constant output range. These parameters
rarely need to be changed.
u E2: Motor Parameters
These parameters contain the motor data for induction motors. They are set automatically when Auto-Tuning is
performed (this includes Rotational and Stationary Auto-Tuning). If Auto-Tuning cannot be performed, then manually
enter the motor data directly to these parameters.
n
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.
No.
E2-01
Note: Setting the motor rated current in E2-01 lower than the motor no-load current in E2-03 will trigger an oPE02 error. 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).
No.
E2-02
If Auto-Tuning cannot be performed, calculate the motor slip using the information on the motor nameplate and the
formula below:
E2-02 = f - (n . p) / 120
f: rated frequency [Hz], n: motor rated speed [r/min], p: number of motor poles
n
E2-03: Motor No-Load Current
Set the no-load current for the motor 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, Stationary Auto-Tuning). The motor no-load
current listed in the motor test report can also be entered to E2-03 manually. Contact the motor manufacturer to receive a
copy of the motor test report.
