SummaryChoosing the right profile can improve smoothness, reduce wear, and lower transfer times for a broad range of motion control applications. Trapezoidal profiles are useful, but limited, because there is no way to define transitions between acceleration regions. S-curves solve this problem, but are correspondingly more complex mathematically. Another important profile for point-to-point moves is the parabolic profile, generally used only for step-motor based systems. Table-based approaches to motion profiling are also popular, and in particular, downloadable electronic cams are widely used in a number of industries.

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
Description: The POSYS® 1800-PIEZO, POSYS® and 1900-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. |
