7) Interpolation at x- and y-axes (Y0/Y1) results in output complete interrupt of only one pulse.
8) The "interrupt enabling ag bit" of special elements must be set. See the following table.

9) The pulse output is stopped.
The pulse output can be stopped by setting the "pulse output stop ag bit" of special elements. See the
following table.

Functions and actions
Because the relay is not applicable to high-frequency actions, this instruction is applicable only to the
PLC of the transistor output type. This instruction is used to continuously output pulses at the pulse width
specied by S1 through the port specied by D within the pulse period specied by S2.
