6.12.3 Mechanical properties analysis
This function is available on Motion Studio. Mechanical properties analysis is used to
determine mechanical resonance and to use filter to suppress the resonance.
6.13 Position comparison
Position comparison is achieved by using instantaneous position data in comparison with
preset position in position parameters. When the condition(s) is fulfilled, a pulse width
configurable DO signal or ABZ/OCZ signal through frequency divider will be delivered. This
function is operated in CPLD, without communication delay between processors hence it is
suitable for application where high velocity motion is required.
