5.5 E: Motor Parameters
188 YASKAWA ELECTRIC SIEP C710616 38F YASKAWA AC Drive - L1000A Technical Manual
The availability of the following parameters depends on the control mode.
Figure 5. 13
Figure 5.13 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 = 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.
◆ E2: Motor Parameters
These parameters contain the motor data for induction motors. They are set automatically when Auto-Tuning is
performed (this includes Rotational Auto-Tuning, Stationary Auto-Tuning 1 and 2). If Auto-Tuning cannot be performed,
refer to Auto-Tuning Fault Detection on page 307.
Note: As the motor parameters for a PM motor are set up in the E5- parameters, parameters for induction motors (E2-) are
hidden when a PM motor control mode is selected (i.e., parameter A1-02 is set to 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.
Note: 1. The display resolution depends on the rated output power of the drive. Models CIMR-LU20008 to 20033, 40005 to 40018,
and 50003 to 50013 display values in 0.01 A units, while models CIMR-LU20047 to 20415, 40024 to 40605, and
50017 to 50200 display values in 0.1 A units.
2. 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.
■ 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).
