OverviewMain Features
Based on the latest DSP (digital signal processor) technology, Leadshine DM series full digital stepper drives offer excellent performance for stepper motor controls.
Those stepper motor drives feature anti resonances for low to middle speed movements. They can drive all 2/3 stepper motors from NEMA to 42 at very smooth movements with very low motor & drive heating. Compared with most analog stepper drives (CPLD chip based), noise can be reduced up to 70%.
Taking step & direction control commands, DM series stepper motor drives are easy to set up. There is a wide choice for DM steppe motor drives to suit input voltage from 18 VDC to direct 120/230 VAC, and output current of 0.1 to 8.2A.
DM series stepper drives have been widely in hundreds of OEM applications such as CNC routers, laser engravers/cutters, printers, milling machines, medical equipments, lab automation instruments, packaging machines...

EM series stepper motor drives offer electronic damping for 3 major resonance frequencies for stepper motors at low speed range. That can eliminate undesirable motor speed oscillation and deliver servo-like smoothness.

Middle speed resonance is the nature for all stepper motors, usual in the speed range of 500-800 RPM. It causes noise,vibration, or even motor movement stalls. By implementing an advanced control algorithm, Leadshine EM series stepper drives calculate resonance frequencies, and thus null them for much better motor movement performance.

When compared with analog stepper drives (CPLD,FPGA), DM series stepper drives can reduce motor heating up to 70% motor noise.This makes DM series stepper drives ideal solutions for many applications with high requirements for motor noise, such as medical devices, lab automation equipment …

Motor heating is seen in all stepper applications. Performance of the driving stepper drives play an important role in the overall heating generated. For many applications, analog stepper drives can’t satisfy application the needs of low motor requirements, because of installing space and available radiating device. But compared with analog stepper drives , Leadshine DM series DSP-based stepper drives can reduce motor heating for 10 to 20°C and thus significantly improve overall system performance, extend motor life time, and save energy.

DM series stepper drives have the feature of command signal smoothing, which can soften the effects of sudden changes in velocity and direction. Therefore, they can deliver much motor movement performance for both quietness and smoothness. This feature makes DM series stepper motor drives ideal for many software based CNC software such as Mach 3 and EMC.

DM Series stepper motor drives implement a technology called "Multi-stepping", which allows a low resolution pulse input further divided into "sub-pulses" for smoother system performance. This function can improve smoothness of the stepper systems without upgrading your motion controllers.
