1.1 Product Introduction
The FT70 features three built-in functions optimized for driving a gantry to provide an optimal
solution for problems with gantry mechanisms.
• Position Correction Table (minimizes wasted torque produced by mechanical differences to
improve cycle times)
• Synchronized Stopping (prevents mechanical damage if alarms occur)
• Position Deviation between Axes Overflow Detection (detects twisting of the machine frame
to prevent mechanical damage and provide a useful function for preventative maintenance)
