DMA860H The driver adopts differential interface circuit applicable to differential signal, single-terminal common negative and common positive interfaces, built-in high-speed optocoupler, allowing the reception of long line driver, collector open circuit and PNP output circuit signals. In harsh environments, we recommend the use of long - line driver circuit, strong anti - interference ability.
Pulse control signal: the pulse rising edge is effective; PUL- 4 ~ 5V at high voltage and 0 ~ 0.5v at low voltage. To reliably respond to pulse signals, the pulse width should be greater than 1.2 microns. Series resistance is required if +12V or +24V is used.
Direction signal: high/low level signal. To ensure reliable commutation, the direction signal should be established at least five microns before the pulse signal. The initial running direction of the motor is related to the wiring of the motor. Interchanging any phase windings (such as A+, A- switching) can change the initial running direction of the motor, DIR- 4 ~ 5V at high voltage and 0 ~ 0.5v at low voltage.
Enable signal: this input signal is used to enable or disable. When ENA+ is connected to +5V and ENA- is connected to low level (or internal optocoupler conduction), the driver will cut off the current of each phase of the motor to make the motor in a free state.
