SIEPYEUOQ2A01A AC Drive Q2A Technical Manual 617
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]
• 7 [PM CLVector]
• 8 [EZ Vector]
■ E2-01 Mot Rated Current (FLA)
No.
(Hex.)
Name Description
Default
(Range)
E2-01
(030E)
Mot Rated Current (FLA)
Sets the motor rated current in amps.
Determined by o2-04 and
C6-01
(10% to 200% of the drive
rated current)
Note:
• If E2-01 < E2-03 [Mot Rated Current (FLA) < Mot No-Load Current] the drive will detect oPE02 [Parameter Range Setting Error].
• The default settings and setting ranges are in these units:
–0.01 A: 4002 to 4023
–0.1 A: 4031 to 4675
The value set for E2-01 becomes the reference value for motor protection, the torque limit, and torque control.
Enter the motor rated current as written on the motor nameplate. The value of E2-01 is automatically set to the
value input for “Motor Rated Current” by the Auto-Tuning process.
■ E2-02 Mot Rated Slip
No.
(Hex.)
Name Description
Default
(Range)
E2-02
(030F)
Mot 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 Mot No-Load Current
No.
(Hex.)
Name Description
Default
(Range)
E2-03
(0310)
Mot 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 and
C6-01
(0 to E2-01)
Note:
The default settings and setting ranges are in these units:
• 0.01 A: 4002 to 4023
• 0.1 A: 4031 to 4675
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. Contact the motor
manufacturer to receive a copy of the motor test report.
Note:
The default setting of the no-load current is for operation with a 4-pole motor recommended by the manufacturer.
■ E2-04 Motor Pole Count
No.
(Hex.)
Name Description
Default
(Range)
E2-04
(0311)
Motor Pole Count
Sets the number of motor poles.
