output system)
Hall effect sensor inputs
High when IN + > IN - , low for the reverse state.
Signal inputs with an amplitude (differential) of at
least 50mVp-p are desirable for the Hall inputs.
If noise is a problem, connect capacitors between
the IN + and IN - inputs.
Forward/reverse control
Low: forward, high or open: reverse.
No connection.
The NC pins may be used for wiring connections.
Frame connection
The FRAME pin is connected internally to the IC
surface metal parts. Both must be used in the
electrically open state.
