P1 Function

DM542 Details

PUL

Pulse signal: Pulse active at rising edge; 4-5V when PUL-HIGH, 0-0.5V when PUL-LOW. Minimal pulse width of 2.5μs. Add a resistor for current-limiting at +12V or +24V input logic voltage (1K for +12V, 2k for +24V). The same as DIR and ENA signals.

DIR

DIR signal:This signal has low/high voltage levels to represent two directions of motor rotation.. Minimal direction setup time of 5μs. Also swapping the connection of two wires of a coil (e.g. A+ and A-) to the drive will reverse motor direction.

ENA

Enable signal: This signal is used for enabling/disabling the drive. High level +5V (NPN control signal) for enabling the drive and low level for disabling the drive. PNP and Differential control signals are on the contrary, namely Low level for enabling. By default it is left UNCONNECTED (ENABLED).
