E4: Motor 2 Parameters
E4 parameters [Motor 2 Parameters]
set induction motor data. To switch drive operation from one motor to a
different motor, configure motor 2.
Auto-Tuning automatically sets the
E4 parameters
to the best values for the application. If you cannot do Auto-
Tuning, set the
E4 parameters
manually.
Note:
E3-xx
and
E4-xx
are available when
H1-xx = 16 [MFDI Function Select = Motor 2 Selection]
.
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 amperes.
Determined by o2-04
(10% to 200% of the
drive rated current)
Note:
•
If
E4-01 ≤ E4-03 [Motor 2 Rated No-Load Current]
is set,
oPE02 [Parameter Range Setting Error]
will be detected.
•
The default settings and setting ranges appear in the following units:
–
2003 to 2033, 4002 to 4018: 0.01 A units
–
2047 to 2415, 4024 to 4605: 0.1 A units
The value set for
E4-01
becomes the reference value for motor protection and the torque limit. Enter the motor
rated current as shown on the motor nameplate. The value of
E4-01
is automatically set to the value input for
[Motor Rated Current] by the Auto-Tuning process.
E4-02: Motor 2 Rated Slip
No.
(Hex.)
Name
Description
Default
(Range)
E4-02
(0322)
Motor 2 Rated Slip
Sets the amount of motor 2 rated slip.
Determined by o2-04
(0.000 - 20.000 Hz)
The setting value of
E4-02
is the slip compensation reference value. The drive sets this parameter during the
Auto-Tuning process (Rotational Auto-Tuning and Stationary Auto-Tuning). If Auto-Tuning cannot be performed,
calculate the motor rated slip using the information written on the motor nameplate and the formula below:
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 amperes when operating at the rated
frequency and the no-load voltage.
Determined by o2-04
(0 to E4-01)
Note:
The default settings and setting ranges appear in the following units:
•
2003 to 2033, 4002 to 4018: 0.01 A units
•
2047 to 2415, 4024 to 4605: 0.1 A units
The drive sets this parameter during the Auto-Tuning process (Rotational Auto-Tuning and Stationary Auto-
Tuning). The motor no-load current listed in the motor test report can also be entered to E2-03 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 performance with a 4-pole motor recommended by Yaskawa.
