2. Monitoring the current number of generated pulses
The number of pulses output from Y000 or Y001 is stored in the following special data resistors.
*1. The FX
0, FX0S, FX0N, FXU or FX2C PLC is not compatible with this function.
*2. The FX
0, FX0S or FX0N PLC is not compatible with this function.
The FX
U PLC of V3.07 or later is compatible.
The contents of each data register can be cleared using the following program.
3. How to stop the pulse output
• When the command input is set to OFF, the pulse generation is immediately stopped. When the command
input is set to ON again, pulse generation operation restarts from the beginning.
• When the special auxiliary relays (M) shown below are set to ON, the pulse output is stopped.
To restart pulse output, set the device corresponding to the output signal to OFF, and then drive the pulse
output instruction again.
