Pulse Signal: In single pulse (pulse/direction) mode, this input represents pulse signal, each
rising or falling edge active (software configurable, see DM drives software operational
manual for the detail); In double pulse mode (software configurable), this input represents
clockwise (CW) pulse, active both at high level and low level. 4-5V when PUL-HIGH,
0-0.5V when PUL-LOW. For reliable response, pulse width should be longer than 2.5μs.
Series connect resistors for current-limiting when +12V or +24V used. The same as DIR and
ENA signal.

Direction Signal: In single-pulse mode, this signal has low/high voltage levels, representing
two directions of motor rotation. In double-pulse mode (software configurable), this signal is
counter-clock (CCW) pulse, active both at high level and low level. For reliable motion
