hen teaching with/without a workpiece, the best sensing method will be
automatically selected (RGB ratio (C Mode) or light intensity determination (I
Mode)). If color differences are not strong enough and RGB ratios would result
in unstable detection, then light intensity determination (I Mode) will be selected.
The detection mode can be set to C, I, or Black Mode.
*3. Input Specifications
Refer to the Instruction Manual for the external input pulse width.
A pulse width of 300 ms or longer is required to switch banks for the E3X-DAC
@
B-S.
*4. Mutual interference prevention cannot be used in super-high-speed mode,
and light intensity determination (I Mode) must be used. The response time
will be 150

D or OR is set for the control outputs.

ith light intensity determination (I Mode and Black Mode), the correlation is
not displayed, but rather the light intensity is displayed.
