Overview
This instruction is used to continuously output a specied number of output pulses at the output frequency
specied at each segment through the specied output port. The action is based on the relative position.
During running, acceleration/deceleration is supported, but the direction cannot be changed.

Functions and actions
This instruction is used to output a specied number of pulses at the specied frequency and in the
specied direction through the specied port; continue to output a specied number of pulses after an
interrupt signal is detected; and drive the servo actuator to move with the given offset based on the current
position. This instruction is applicable only to the PLC of the transistor output type. Wherein:
S1 indicates the specied number of pulses to be output at the rst segment. The number of pulses to
be output at other segments is stored in subsequent consecutive elements. For a 16-bit instruction, the
range is -32768 to 32,767. For a 32-bit instruction, the range is -2,147,483,648 to +2,147,483,647. The "-"
indicates the reverse direction. The pulse output direction is determined by whether the value is positive or
negative.
