PULS(886) sets the pulse type and number of pulses specified in T and N for the port specified in P.

Actual output of the pulses is started later in the program using SPED(885) or ACC(888) in independent

• An error will occur if PULS(886) is executed when pulses are already being output. Use the differentiated

version (@PULS(886)) of the instruction or an execution condition that is turned ON only for one scan to

prevent this.

• The calculated number of pulses output for PULS(886) will not change even if INI(880) is used to change

the PV of the pulse output.

• The direction set for SPED(885) or ACC(888) will be ignored if the number of pulses is set with

PULS(881) as an absolute value.

Example Programming

When CIO 0.00 turns ON in the following programming example, PULS(886) sets the number of output

pulses for pulse output 0. An absolute value of 5,000 pulses is set. SPED(885) is executed next to start

pulse output using the CW/CCW method in the clockwise direction in independent mode at a target

frequency of 500 pps.

• ON if the specified range for P, T, or N is exceeded.

• ON if PULS(886) is executed for a port that is already outputting pulses.

• ON if PULS(886) is executed in an interrupt task when an instruction controlling pulse output is being executed in a

cyclic task.

• For a CJ2M CPU Unit, ON for any function that uses I/O on the Pulse I/O Module even if a Pulse I/O Module is not

• OFF in all other cases.
