The ZETA4 stand-alone, packaged microstepping drives incorporate patented, breakthrough techniques know as Active Damping™ and Electronic Viscosity™ for the smoothest and highest quality motion. The ZETA4 provides 4Apk output, a resolution of 50,800 steps/rev for excellent motor speed and torque and accepts industry standard step/direction or CW/CCW command signals for easy motion controller connectivity.

Markets:
• Semicon/Electronics
• Packaging
• Scientific and Energy Research
• Laser based Manufacturing

Features/Benefits:
• Standard step-and-direction input or CW/CCW input is compatible with any motion controller
 • Active Damping™:
 - Higher acceleration than conventional step systems allows more efficient use of motor capacity
 - Decreases motor vibration and increases shaft power for better high speed process quality
 • Electronic Viscosity™
- Reduces settling time for increased throughput
- Increases slow speed smoothness/reduce velocity ripple for better inspection quality
 - Reduces audible noise
 • Automatic Standby Current Reduction reduces motor temperature to minimize impact on object under test

Applications:
• Inspection and scanning machines
• Package and label printing
• Laser etching and cutting

Protection Circuit
 • Motor short circuits (phase-to-phase and phase-to-ground)
 • Overtemperature
 • Undervoltage
 • Power dump (dissipates excess energy caused by load regeneration)

Physical
 • Drive status indicators: power, step input, over temperature and motor fault
 • Removable connectors for easy installation
 • Selectable damping for optimized performance
