Note : All above is normally used, and we can customize according to your request or choose the suitable model for you.

Character
1.Operating voltage: AC85 to 265VAC, advice 110VAC or 220VAC,the max output peak current is 7.0A                  
2.Using flux linkage anti-resonance algorithm and electronic damping low-speed anti-vibration algorithm,the driver and motor have low temperature
3.Pulse, direction compatible with enable signal interface level 4.5-28Vdc , no external current limiting resistor
4.Automatic identify of motor parameters and automatic adjustment of control parameters when power on
5.Built-in micro-step subdivision algorithm to achieve low-subdivision control instructions, high-subdivision operation results,good stability
6.Using high pressure and low voltage isolation program inside,the reliability is very high
7.Automatic identify of motor parameters and automatic adjustment of control parameters when power on
8.Control mode: pulse / direction mode or dual pulse input mode 
9.The max pulse frequency of the control command is 200KHz
10.Provide 16 positions of conventional micro-step subdivision set value,The highest resolution is 40000

Application
Novotech driver used in marking machine, cutting machine, laser phototypesetting, plotter, transmission power lines, automatic assembly and other equipments. It suitable for a lot of small and medium-sized automation equipments and instruments, has outstanding performance in the equipments that users expect small noise and high-speed.
