Note:
•
Set this parameter to 0.0 to disable the function.
• When you initialize the drive, this parameter is reset to the default value.

M2 Min Out Voltage
Sets a middle output voltage for the motor 2 V/f pattern. Set this parameter to adjust the V/f
pattern for the constant output range. Usually it is not necessary to change this setting.
0.0 V
(400 V Class: 0.0 - 510.0
V)
Note:
•
Set this parameter to 0.0 to disable the function.
•
When you initialize the drive, this parameter is reset to the default value.
• The setting value changes automatically when you do Auto-Tuning (rotational and stationary 1 or 2).

M2 Base Voltage
Sets the base voltage for the motor 2 V/f pattern. Set this parameter to adjust the V/f pattern for
the constant output range. Usually it is not necessary to change this setting.
0.0 V
(400 V Class: 0.0 - 510.0

Note:
•
When you initialize the drive, this parameter is reset to the default value.
•
The setting value changes automatically when you do Auto-Tuning (rotational and stationary 1 or 2).
◆
E4: MOTOR 2 PARAMETERS
E4 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 = 61 [DI Function Select = Motor 2 Select] .
■
E4-01 M2 Rated Current (FLA)
No.
(Hex.)
Name Description
Default
(Range)
E4-01
(0321)
M2 Rated Current (FLA)
Sets the motor rated current for motor 2 in amps.
Determined by o2-04 and
C6-01
(10% to 200% of the drive
rated current)
Note:
• If E4-01 ≤ E4-03 [M2 No-Load Current] , the drive will detect oPE02 [Parameter Range Setting Error] will be detected.
•
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 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 M2 Rated Slip
No.
(Hex.)
Name Description
Default
(Range)
E4-02
(0322)
M2 Rated Slip
Sets the motor rated slip for motor 2.
Determined by o2-04 and
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:
