Features 

„

 

Brand-new technology 

- Advanced current control 

- Micro step emulation provides smooth motion even with low step resolutions 

- Anti-resonance algorithm eliminates the mid-range instability 

- Torque ripple smoothing algorithm adjusts waveform to reduce low speed torque ripple 

- Command signal dynamic smoothing algorithm makes the motor motion less jerky 

„

 

Multiple operating modes 

- Step & Direction 

- CW/CCW 

- Encoder following 

- Analog velocity or digital velocity 

- SCL Host commands for real time control from a host PC or PLC using RS-232 serial 
communication
