2. Monitoring the number of generated pulses
The number of pulses output from Y000 or Y001 is stored in the following special data registers:

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.

Cautions
1. Frequency
S
1
When using transistor outputs on the main unit, set the output frequency
If the load is operated using pulses at a frequency higher than 100,000 Hz from transistor outputs in the main unit, the
PLC may be damaged.
2. Pulse output
• Only a transistor output on the main unit or Y000 or Y001 on a special high-speed output adapter*1 can be
specified in
D
*1.
High-speed output special adapters can be connected only to FX
When using the PLSR (FNC 59) instruction with a relay output type or triac output type FX
high-speed output adapter is required.
• The duration of the ON/OFF pulses is 50% (ON = 50%, OFF = 50%).
• The pulse output is controlled by the dedicated hardware not affected by the sequence program (operation cycle).
• If the command input is set to OFF during continuous pulse output, the output from
