2.2 Operating Status LEDs
The LEDs display the operating status of two axes at a time. If the unit is of 4-axis type, use
the switch to toggle between the operating status display of the 1st and 2nd axes and that of
the 3rd and 4-axes. The contents of the LED display are the same in each axis.

(Note 1): The LED for the pulse output A-signal flashes at a cycle (speed) of output frequency, thus looking as if it
were continuously lit if the speed is high. So is the LED for the pulse output B-signal.
(Note 2): Near home input (D) and home input (Z) will be lit if the respective inputs are enabled.
(Note 3) The input status of pulse input signals (PA) and (PB) will be displayed.
(Note 4) The LEDs may be continuously lit with or without pulse output if the electronic clutch or electronic cam is in
operation.
