Notes on Sample Application Circuit
*1. Rf is determined by starting torque required for coil impedance F/V conversion voltage (control input). Rf should be
0.3Ω to 5Ω.
*2. Cf is for stopping oscillation and is determined by motor characteristic and F/V converter-included closed loop
characteristic. Cf should be 0.022µF to 0.047µF.
*3. For how to connect Hall element, either parallel connection or series connection is available as long as input voltage
is within the range specified.
