3. Control signal port
| Name | Description |
| PUL+ | Pulse input signal:Pulse active edge adjustable, default pulse rising edge; reliable response to the pulse signal, the pulse width should be greater than 1.2μs. Such as using + 12V or + 24V is necessary series resistance. |
| PUL- | |
| DIR+ | Direction input signal:High / low signal, in order to ensure reliable motor commutation, direction signal should be at least 5μs pulse signal is created. Such as using + 12V or + 24V is necessary series resistance. |
| DIR- | |
| ENA+ |
Enable control signal, the input signal is used to enable or disable the driver output. ENA low-level (or internal optocoupler conducting), the drive will cut off the motor current phase of each motor is in a free state, not in response to the input signal pulses. When not required for this feature to enable signal terminal vacant. Such as using + 12V or + 24V is necessary series resistance. |
| ENA- | |
| ALM+ |
Fault signal output, open-collector form. Fault output logic can be set by PC software. |
