Setting With Au2: Torque Boost Macro; Setting With F400: Offline Auto-Tuning; Vector Control 1; Three Parameter Setting Methods - Toshiba TOSVERT VF-AS3 Instruction Manual

When the motor you are using is a 4P Toshiba general motor which has the same capacity as the
inverter, there is basically no need to set the parameters.
First, look at the motor name plate and set the following parameters.
• <vL: Base frequency 1> (Rated frequency)
• <vLv: Base frequency voltage 1> (Rated voltage)
• <F405: Motor rated capacity>
• <F415: Motor rated current>
• <F417: Motor rated speed>
Next, perform auto-tuning. Two parameter setting methods are provided.
1) Setting with <AU2: Torque boost macro>
Set <AU2: Torque boost macro> to "1". Set <Pt> to "2: Automatic torque boost" and <F400:
Offline auto-tuning> to "2" simultaneously.
For details, refer to [5. 2. 5].
2) Setting with <F400: Offline auto-tuning>
4
Set <F400: Offline auto-tuning> to "5".
For details, refer to [6. 23. 1].
* If an auto-tuning error occurs, set motor parameters individually by referring to [6. 23. 1]

3: Vector control 1

High-torque and high-precision stable operation is realized in the speed range from startup to base
frequency.
It is applied to load transporting machinery and elevators that require high torque and machine tools
that require high precision.
• High starting torque can be obtained.
9
• It is effective when smooth stable operation from a low speed is required.
• The change of motor speed caused by load fluctuation is suppressed to realize high-precision
operation.
When <Pt> is "3", setting of motor parameters is required.
When the motor you are using is a 4P Toshiba general motor which has the same capacity as the
inverter, there is basically no need to set the parameters.
In other cases, look at the motor name plate and set the following parameters.
• <vL: Base frequency 1> (Rated frequency)
• <vLv: Base frequency voltage 1> (Rated voltage)
• <F405: Motor rated capacity>
• <F415: Motor rated current>
• <F417: Motor rated speed>
Three parameter setting methods are provided.
1) Setting with <AU2: Torque boost macro>
Set <AU2: Torque boost macro> to "2". Set <Pt> to "3: Vector control 1" and <F400: Offline
auto-tuning> to "2" simultaneously.
For details, refer to [5. 2. 5].
2) Setting with <F400: Offline auto-tuning>
Set <F400: Offline auto-tuning> to "5".
For details, refer to [6. 23. 1].
