■ 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
(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: 4009
–0.1 A: 4015 to 4045
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: Motor Rated Slip
No.
(Hex.)
Name Description
Default
(Range)
E2-02
(030F)
Motor Rated Slip
Sets motor rated slip.
Determined by o2-04
(0.00 - 20.00 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
(0 to E2-01)
Note:
When the drive model changes, the display units for this parameter also change.
• 0.01 A: 4009
• 0.1 A: 4015 - 4045
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.
■ E2-04: Motor Pole Count
No.
(Hex.)
Name Description
Default
(Range)
E2-04
(0311)
Motor Pole Count
Sets the number of motor poles.
4
(2 - 48)
Auto-Tuning automatically sets this parameter to the value of [Number of Motor Poles].
■ E2-05: Motor Line-to-Line Resistance
No.
(Hex.)
Name Description
Default
(Range)
E2-05
(0312)
Motor Line-to-Line
Resistance
Sets the line-to-line resistance for the motor stator windings.
Determined by o2-04
(0.000 - 65.000 Ω)
