M752L Stepper Motor Driver’s Connector P1 Configurations
| Pin Function | Details |
| PUL+(+5V) | Pulse signal: In single pulse pulse/direction) mode, this input represents pulse signal, effective for each rising or falling edge (set by inside jumpers in JP1); 4-5V when PUL-HIGH, 0-0.5V when PUL-LOW. In double pulse mode (pulse/pulse) , this input represents clockwise (CW) pulse,effective for high level or low level (set by inside jumpers in JP1). For reliable response, pulse width should be longer than 1.5μs. Series connect resistors for current-limiting when +12V or +24V used. |
| PUL-(PUL) | |
| DIR+(+5V) | DIR signal: In single-pulse mode, this signal has low/high voltage levels,representing two directions of motor rotation; in double-pulse mode (set by inside jumper J3), this signal is counter-clock (CCW) pulse,effective for high level or low level (set by inside jumper J1). For reliable motion response, DIR signal should be ahead of PUL signal by 5μs at least. 4-5V when DIR-HIGH,0-0.5V when DIR-LOW. |
| DIR-(DIR) | |
| ENA+(+5V) | Enable signal: This signal is used for enabling/disabling the driver. High level (NPN control signal, PNP and Differential control signals are on the contrary,namely Low level for enabling.) for enabling the driver and low level for disabling the driver. Usually left UNCONNECTED (ENABLED). |
