Handling Precautions
a) At 3ST input, because the input voltage ranges for V
b) When controlling the rotation direction using 3ST input, switch the direction from Reverse to Stop mode or
A Hall IC input amplitude of over 400 mV

Particular care is necessary in the design of the output, V
due to short circuits between output air contamination faults, or faults caused by improper grounding
Note 3: Set an appropriate value depending on the motor and use conditions.
Note 4: Be sure to set this bias so that the Hall element output amplitude and common-mode input voltage fall within
