BOBOYA Stepper Motor Driver CNC Digital Controller DMA860H for 2 Phase Stepping Motor CNC Router Engraving Machine,Driver
About this product
*APPLICATION: stepper motor driver is suitable for all kinds of large and medium-sized automation equipment, such as column engraving machines, etc
*SETTINGS: Current Settings of this stepper motor driver are handy and optional between 2.4 and 7.2 (peak)
*DIGITAL: DMA860H is a low-noise digital stepper motor driver, using a new 32-bit digital signal processor technology, which can meet the application needs of most occasions
*AUTO-TUNING: The stepper motor driver has integrated parameter auto-tuning function, which can automatically generate operating parameters for different motors and give full play to the click performance
*HIGH SUBDIVISION EFFECT: digital stepper motor driver can achieve high subdivision effect, low, medium and high speed operation is very stable, and the noise is very small
Description
Description
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.
Features
Stepper motor driver
-Color: Black.
-Material: Plastic.
-Size:12x7x4 cm/4.72x2.76x1.57 inch.
Model Number: DMA860H
Can drive 4,6,8 line two-phase stepper motor
Voltage input range: 18-80VAC
Current maximum: 7.2A, resolution: 0.1A
Subdivision range: 400~51200
Pulse response frequency: 200KHZ
Signal input: differential / single-ended, pulse / direction or double pulse
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.
