Signal function and timing.
The description below shows how to connect the pulse source when using the pulse and
direction format. Also the timing is shown. Please be aware that if the indicated minimum
timing is not respected the motor may loose some of the step clocks and the position of
the motor will end up being out of synchronism with the pulse generator.
The description below shows how to connect the pulse source when using the quadra-
ture format. Also the timing is shown. Please be aware that if the indicated minimum tim-
ing is not respected the motor may loose some of the step clocks and the position of the

The Direction signal must stay stable and well defined
in the indicated period while the clock has a rising edge.
Step occurs on the
leading flank
Motor moves CW when
direction is high (1) and
CCW when low (0).
