E4: Motor 2 Parameters - YASKAWA L1000A Technical Manual

5.5 E: Motor Parameters

◆ 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 1 and 2). They may need to be set
manually if there is a problem performing Auto-Tuning.
Note: The function for switching between two motors cannot be used with a PM motor. E4-
motor control mode is selected (A1-02 = 5, 6, or 7).
■
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.
No.
E4-01
Note: 1. The display resolution depends on the rated output power of the drive. Models CIMR-L 2A0018 to 0033 and CIMR-L 4A0009 to
0018 display values in 0.01 A units, while models CIMR-L 2A0047 to 2A0415 and CIMR-L 4A0024 to 4A0260 display values in
0.1 A units.
2. 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.
■
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 1, 2).
Refer to E2-02: Motor Rated Slip on page 170
No.
E4-02
■
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 1, 2). 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.
No.
E4-03
Note: The display resolution depends on the rated output power of the drive. Models CIMR-L 2A0018 to 0033 and CIMR-L 4A0009
to 0018 display values in 0.01 A units, while models CIMR-L 2A0047 to 2A0415 and CIMR-L 4A0024 to 4A0260 display
values in 0.1 A units.
■
E4-04: Motor 2 Motor Poles
Sets the number of poles for motor 2. If Auto-Tuning completes successfully, the value entered to T1-06 will be
automatically saved to E4-04.
No.
