Ultra-Low Noise SWT-256M subdivision 2-phase stepping motor driver,use to automation equipment and instruments
Ultra-Low Noise SWT-256M
Stepper Motor Driver
I. Overview
SWT-256M stepper motor driver applied advanced pure sine Precision
Current control technology with high-performance subdivision. The
pure sine precise current control technique can improve the
operation effect close to the servo motor level.
This drive also has fine subdivisions, small volume, a variety of
protection can be automatic half flow and other functions. The
operation voltage can be reach to 40VDC.
2:Wiring instructions
1.P1 Weak current signal wiring
| Signal | Function |
| PUL+(+5V) | pulse signal: Pulse rising effective; PUL-:High-level 4-5V,Low-level 0-0.5V, Pulse width more than 1μS for more reliable response. connect resistor for current-limiting if input +12V or 24V |
| PUL-(PUL) | |
| DIR+(+5V) | direction signal: its High-level/Low-level signal, For reliable
motor response, the corresponding motor direction is needed,. The
direction signal should be established prior to the pulse signal at
least 5μs, |
| DIR-(DIR) | |
| ENA+(+5V) | enable signal: the input signal is used to enable/disable,, High-levels: enable, Low-levels: disable. please connect ENA+and ENA- for normal use, disconnection is auto-enable mode |
| ENA-(ENA) |
2.P2 Strong current wiring
| Port | Function |
| GND | DC GROUNDED |
| +V | DC positive pole:+30V-+40V,recommended value +36VDC |
| A+,A- | Motor A Phase. interconvert A+,A-, can change the direction of motor. |
| B+,B- | Motor B Phase. interconvert B+,B-, can change the direction of motor. |

(2) Static current setting
Static current can be set by SW4,"OFF" means static current is half
of dynamic current, ,"ON "means static current is same as dynamic
current,
