Explanation
DIR+
(J4-22)
Optically isolated 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 and A OR B
and B). Refer to the figure at the end of
the table for timing and circuit
information.
DIR-
(J4-10)
(J4-23)
Optically isolated input used to enable or
disable the 6415’s power stage. With the
enable sense (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 500ms after enabling the
drive and power stage becoming active.
ENABLE-
(J4-11)
STEP_OUT
(J4-12, 13,
24, 25)
The VCO output step pulses rate is
proportional to the analog speed
command and available to connected up
to four additional 6410 drives.
