J1 signal table
Note: All inputs and outputs are optically isolated.
Input/Output Pin Explanation
STEP + J1-1 Input used to command motor rotation. See figure at
the end of the table for circuit and timing information.
DIR + J1-2 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 + J1-3 Input used to enable or disable the 6410’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
Collector
J1-4 Output. Collector of transistor that is on when the
6410’s power stage is active. See figure at the end of
the table for circuit information.
J1-5 Not used.
STEP - J1-6 Input used to command motor rotation. See figure at
the end of the table for circuit and timing information.
