(2) Positioning accuracy
The traveling amount for interrupt positioning is the value corresponding to the feedback position.
The interrupt input signal is subject to the delay in detection of the hardware filter (0.05 ms)
The positioning accuracy at a mechanical system traveling speed of 1000 mm/s (60 m/min) is:
1000 x 0.00005 = 0.05 mm.
Generally, the sensor used for interrupt input has some delays from electrical factors, which are
the deviation in detection and the delay in output. The interrupt positioning accuracy is determined
after synthesizing these factors and mechanical accuracy (such as distortion, backlash, and
expansion).
(3) Interrupt positioning detection
The interrupt positioning detection is an output signal, which is output during interrupt positioning
motion by being assigned to the OUT output signals.
To assign interrupt positioning detection to a sequence input terminal, specify the corresponding
value ("85") to the output terminal function setting parameter.
