12.6 E: Motor Parameters
826 YASKAWA SIEPC71061737D GA800 Drive Technical Reference
Note:
If A1-02 [Control Method Selection] is set to the following control modes, the keypad does not display E2-xx.
• 5 [PM Open Loop Vector]
• 6 [PM Advanced Open Loop Vector]
• 7 [PM Closed Loop Vector]
• 8 [EZ Vector Control]
■ E2-01: Motor Rated Current (FLA)
No.
(Hex.)
Name Description
Default
(Range)
E2-01
(030E)
Motor Rated Current (FLA)
Sets the motor rated current in amps.
Determined by o2-04, C6-01
(10% to 200% of the drive
rated current)
Note:
• If E2-01 < E2-03 [Motor 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: models 2004 - 2042, 4002 - 4023
–0.1 A: models 2056 - 2415, 4031 - 4720, T103 - T720
The value set for E2-01 becomes the reference value for motor protection, the torque limit, and torque control. Enter
the motor rated current written on the motor nameplate. Auto-Tuning the drive will automatically set E2-01 to the
value input for “Motor Rated Current”.
■ E2-02: Motor Rated Slip
No.
(Hex.)
Name Description
Default
(Range)
E2-02
(030F)
Motor Rated Slip
Sets motor rated slip.
Determined by o2-04, C6-01
(0.000 - 20.000 Hz)
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
-1
(r/min))
• p: Number of motor poles
■ E2-03: Motor No-Load Current
No.
(Hex.)
Name Description
Default
(Range)
E2-03
(0310)
Motor No-Load Current
Sets the no-load current for the motor in amps when operating at the rated frequency and the no-load
voltage.
Determined by o2-04, C6-01
(0 to E2-01)
Note:
When the drive model changes, the display units for this parameter also change.
• 0.01 A: 2004 - 2042, 4002 - 4023
• 0.1 A: 2056 - 2415, 4031 - 4720, T103 - T720
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 Yaskawa.
