DC servo-drive CWDS660

two-phasetwo-phase stepperwith encoder

Product Overview
The CWDS660 is a 2-phase closed-loop stepper servo driver designed to overcome the limitations of open-loop stepper systems. It supports up to 6 A at 20-60 VDC and uses a 32-bit DSP with vector control to prevent missed steps, reduce heat generation and improve speed performance by approximately 30%. Factory vector control eliminates the need for parameter tuning.

Key Highlights

• Closed-loop control — eliminates missed steps
• 32-bit DSP with vector control algorithm
• Approx. 30% speed improvement versus open-loop
• Reduced heat generation
• No parameter tuning required
• Compact 118 x 75 x 34 mm form factor
