Explanation
DIR -
J12-7
Input that determines the direction of motor
rotation. If standard motor wiring is followed, the
motor will turn clockwise if the opto current is zero.
The sense of the DIR + input can be reversed by
reversing the connection of either (but not both)
motor phase connectors (i.e. switching A & A OR B
& B). Refer to the figure at the end of the table for
timing and circuit information.
ENABLE -
J12-8
Input used to enable or disable the 6430’s power
stage. With the J6 5-6 jumper out (factory default)
the power stage is enabled if the opto current is
zero and disabled if the opto is driven. Inserting the
jumper reverses this functionality. See figure at the
end of the table for circuit information. There is a
delay of approximately 500
µ
s after enabling the
drive and the power stage becoming active.
Enabled
Emitter
J12-9
Output. Emitter of transistor that is on when the
6430’s power stage is active. See figure at the end
of the table for timing and circuit information.
Typical interface
The figure on the following page shows a typical interface
between the user’s electronics and the 6430. The TTL gates
should have totem pole outputs and be capable of sinking at
least 10.0 mA at 0.4 volts.
