■ E4-01: Motor 2 Rated Current
No.
(Hex.)
Name Description
Default
(Range)
E4-01
(0321)
Motor 2 Rated Current
Sets the motor rated current for motor 2 in amps.
Determined by o2-04, C6-01
(10% to 200% of the drive
rated current)
Note:
• If E4-01 ≤ E4-03 [Motor 2 Rated 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: 2004 - 2042, 4002 - 4023
–0.1 A: 2056 - 2415, 4031 - 4720, T103 - T720
The value set for E4-01 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 automatically sets the value of E4-01 to the
value input for [Motor Rated Current].
■ E4-02: Motor 2 Rated Slip
No.
(Hex.)
Name Description
Default
(Range)
E4-02
(0322)
Motor 2 Rated Slip
Sets the motor rated slip for motor 2.
Determined by o2-04, C6-01
(0.000 - 20.000 Hz)
The value set in E4-02 becomes the base slip compensation value. The drive sets this parameter during Rotational
Auto-Tuning and Stationary Auto-Tuning. If you cannot do Auto-Tuning, use the information written on the motor
nameplate and this formula to calculate the motor rated slip:
E4-02 = f - (n × p) / 120
• f: Motor rated frequency (Hz)
• n: Rated motor speed (min
-1
(r/min))
• p: Number of motor poles
■ E4-03: Motor 2 Rated No-Load Current
No.
(Hex.)
Name Description
Default
(Range)
E4-03
(0323)
Motor 2 Rated No-Load
Current
Sets the no-load current for motor 2 in amps when operating at the rated frequency and the no-load
voltage.
Determined by o2-04, C6-01
(Less than 0 - E4-01)
Note:
The display units are different for different models:
• 0.01 A: 2004 - 2042, 4002 - 4023
• 0.1 A: 2056 - 2415, 4031 - 4720, T103 - T720
You can also manually enter the motor no-load current shown on the motor test report to E4-03. Contact the motor
manufacturer for the motor test report.
Note:
The default setting of the no-load current is for a 4-pole motor recommended by Yaskawa.
■ E4-04: Motor 2 Motor Poles
No.
(Hex.)
Name Description
Default
(Range)
E4-04
(0324)
Motor 2 Motor Poles
Sets the number of poles for motor 2.
4
(2 - 120)
Auto-Tuning automatically sets E4-04 to the value input for [Number of Motor Poles].
