12.5 E: MOTOR
If Auto-Tuning cannot be performed, set the E2 parameters manually. Performing Auto-Tuning automatically sets
the E2 parameters to the optimal values.
Note:
If A1-02 [Control Method] is set to the following control modes, the keypad does not display E2-xx.
• 5 [PM OLVector]
• 6 [PM AOLVector]
• 8 [EZ Vector]
■
E2-01: Mot Rated Current (FLA)
No.
Name
(Hex.)
E2-01 Mot Rated Current (FLA)
(030E)
Note:
• If E2-01 < E2-03 [Mot No-Load Current], the drive will detect oPE02 [Parameter Range Setting Error].
• When the drive model changes, the display units for this parameter also change.
–0.01 A: 2001 to 2042, B001 to B018, 4001 to 4023
–0.1 A: 2056 to 2082, 4031 to 4060
The value set for E2-01 becomes the reference value for motor protection and the torque limit. Enter the motor
rated current written on the motor nameplate. Auto-Tuning the drive will automatically set E2-01 to the value
input for T1-04 [Motor Rated Current].
■
E2-02: Mot Rated Slip
No.
Name
(Hex.)
E2-02 Mot Rated Slip
(030F)
This parameter value becomes the base slip compensation value. The drive automatically sets this parameter
during Auto-Tuning. When you cannot do Auto-Tuning, calculate the motor rated slip with the information on the
motor nameplate and this formula:
E2-02 = f - (n × p) / 120
• f: Motor rated frequency (Hz)
• n: Rated motor speed (min
• p: Number of motor poles
■
E2-03: Mot No-Load Current
No.
Name
(Hex.)
E2-03 Mot No-Load Current
(0310)
Note:
When the drive model changes, the display units for this parameter also change.
• 0.01 A: 2001 to 2042, B001 to B018, 4001 to 4023
• 0.1 A: 2056 to 2082, 4031 to 4060
The drive automatically sets this parameter during Auto-Tuning. When you cannot do Auto-Tuning, you can also
use the motor no-load current on the motor test report to enter this value manually. Get the test report from the
motor manufacturer.
Note:
The default setting of the no-load current is for a 4-pole motor recommended by the manufacturer.
