Motion Control Cards with Special PIEZO (Ceramic) Motor Functions Motion Control Chips with special functions to compensate PIEZO Motor behaviour Products Names: - POSYS® 1800-PIEZO Series
- POSYS® 1900-PIEZO Series
- POSYS® 4000-PIEZO Series
Description: The POSYS® 1800-PIEZO, POSYS® 1900-PIEZO and POSYS® 4000-PIEZO are motion control cards (PC-104, PCI-bus and Standalone) for servo and stepper motors and provide one to four axes of motion. The functionality of these series has been significantly improved by using a special motion control chip with enhanced PIEZO (Ceramic) control functions. It is now possible to compensate the special behaviour of PIEZO (Ceramic) motors like for example stiction. |
