11.6 E: Motor Parameters
YASKAWA ELECTRIC SIEP C710617 05F YASKAWA AC Drive GA700 Technical Manual 807
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: 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
and C6-01
(0 to E2-01)
Note:
The default settings and setting ranges are in these units:
• 0.01 A: 2004 to 2042, 4002 to 4023
• 0.1 A: 2056 to 2415, 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 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 - 120)
Note:
• When A1-02 = 0, 1, 3 [Control Method Selection = V/f, CL-V/f, CLV], the maximum value is 120.
• When A1-02 = 2, 4 [OLV, AOLV], the maximum value is 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
and C6-01
(0.000 - 65.000 Ω)
Note:
This value is the motor line-to-line resistance. Do not set this parameter with the single-phase resistance.
Auto-Tuning automatically sets this parameter. If you cannot do Auto-Tuning, use the test report from the motor
manufacturer. You can calculate the motor line-to-line resistance with one of these formulas:
