 Application samples
In case of "Slicer", it is usually installed following operation method:
- RUN and STOP by remote control.
- Speed adjustment by analog input(0-10V)
- Stable speed by sensor-less vector control
- Emergency stop
 Connection of inveters
In a cutter part, please install a braking resistor for emergency stop.

Setting table for inverters (VF-S15)
You have to set the motor parameter with sensor-less vector control.

3. Execute "AU2(Automatic torque-up function) = 2"
This function automatically executes "Pt" and "F400".
Pt(V/f control selection) = 3(Sensor-less vector control)
F400(Auto-tuning) = 2(Enabled)
The auto-tuning is enabled at the first operation command.
please be careful of your rotating motor shaft.
