6.16 Setting motor constants
: Auto-tuning
: Motor rated current
: Slip frequency gain : Motor no-load current
: Automatic torque boost value : Motor rated speed
: Motor rated capacity : Load inertia moment ratio
To use vector control, automatic torque boost and automatic energy saving, motor constant setting (motor tuning)
is required. The following three methods are available to set motor constants.
1) Using the torque boost setting macro function () for setting the V/F control mode selection () and
auto-tuning () at the same time
2) Setting V/F control mode selection () and auto-tuning () independently
3) Combining the V/F control mode selection () and manual tuning
Caution:
If the settings for V/F control mode selections are : automatic torque boost control, : vector control,
: energy saving.
Look at the motor's name plate and set the following parameters.
: Base frequency 1 (rated frequency)
: Base frequency voltage 1 (rated voltage)
: Motor rated capacity
: Motor rated current
: Motor rated speed
Set the other motor constants as necessary.
[Selection 1: Setting by parameter setting macro torque boost]
This is the easiest of the available methods. It conducts vector control and auto-tuning at the same time.
Be sure to set the motor for , , , , .
Set to (Automatic torque boost + auto-tuning)
Set to (Vector control + auto-tuning)
Set to (Energy-saving + auto-tuning)
Refer to section 5.4 for details of the setting method.
