■ E1-12: Mid Point B Voltage
No.
(Hex.)
Name Description
Default
(Range)
E1-12
(030B)
Expert
Mid Point B Voltage
Sets a middle point voltage for the V/f pattern.
0.0 V
(200 V Class: 0.0 to 255.0 V,
400 V Class: 0.0 to 510.0 V)
Note:
Set this parameter to 0.0 to disable the function.
■ E1-13: Base Voltage
No.
(Hex.)
Name Description
Default
(Range)
E1-13
(030C)
Expert
Base Voltage
Sets the base voltage for the V/f pattern.
0.0 V
(200 V Class: 0.0 - 255.0
V,400 V Class: 0.0 - 510.0
V)
Note:
• After Auto-Tuning, the value of E1-13 = E1-05 [Maximum Output Voltage].
• When E1-13 = 0.0, use the value of E1-05 to control the voltage.
■ E1-21: No-Load Voltage Adjustment
No.
(Hex.)
Name Description
Default
(Range)
E1-21
(1568)
No-Load Voltage
Adjustment
Sets the type of Auto-Tuning. Considers T1-13[PM Motor Rated Voltage] FLA)] to be 100%.
85.0%
(0.0 - 100.0%)
Note:
The default setting is different for different models.
• 85.0%: B001 - B018, 2001 - 2056, 4001 - 4031
• 90.0%: 2070, 2082, 4038 - 4060
◆ E2: Motor Parameters
E2 parameters [Motor Parameters] are used to set induction motor data. To switch drive operation from one motor to
another motor, configure the first motor (motor 1).
If Auto-Tuning cannot be performed, set the E2 parameters manually. Performing Auto-Tuning automatically sets the
E2 parameters to the optimal values.
Note:
If A1-02 [Control Method Selection] is set to the following control modes, the keypad does not display E2-xx.
• 5 [PM Open Loop Vector]
• 6 [PM Advanced Open Loop Vector]
• 8 [EZ Vector Control]
■ E2-01: Motor Rated Current (FLA)
No.
(Hex.)
Name Description
Default
(Range)
E2-01
(030E)
Motor Rated Current (FLA)
Sets the motor rated current in amps.
Determined by o2-04, C6-01
(10% to 200% of the drive
rated current)
Note:
• If E2-01 < E2-03 [Motor 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: B001 to B018, 2001 to 2042, 4001 to 4023
–0.1 A: 2056 to 2082, 4031 to 4060
