Motion
Direction Input
J4 3, 4
The DIRECTION input is similar to the step input except that it
employs a slower opto isolator. Allow for a 55 µs setup time from
changes at the DIR input prior to transition of the STEP input.
Failure to meet setup time can result in the drive misinterpreting the
intended direction of a step.

Step Input
J4 5, 6
The ENABLE input removes current from the motor windings so the
axis can be externally moved. The polarity of the ENABLE logic is
configurable using P7000Tools. Factory default is ENABLE =
ACTIVE OPEN. If the inputs are left open, the drive is enabled.
The input is enabled with 20 mA of current. It is suitable for use
with 3 to 5 volt logic.
The ENABLE input is digitally filtered and
internally de-bounced.
WARNING
Do not depend on the ENABLE input as a safety or E-
STOP mechanism. Internal drive failure could result
in motion. When disabled, the winding terminals are
not at safe potential. The power output from the drive
is electrically safe only when the drive is disconnected
from the power source.
