Phasing

You have four options for the "Phasing" interface to the stepper/servo drive. These options
are as follows:
● PTO (pulse A and direction B): If you select a PTO (pulse A and direction B) option, then
one output (P0) controls the pulsing and one output (P1) controls the direction. P1 is high
(active) if pulsing is in the positive direction. P1 is low (inactive) if pulsing is in the
negative direction:
● PTO (count up A and count down B): If you select a PTO (count up A and count down B)
option, then one output (P0) pulses for positive directions and a different output (P1)
pulses for negative directions:
