Pulse I/O Board Section 2-2
Example 1: Starting
Pulse Output with
PULS(65) and SPED (64)
Starting Pulse Output at Specified Frequency
The following example shows PULS(65) and SPED(64) used to control a
pulse output from port 1. The number of pulses specified in PULS(65)
(10,000) are output as the frequency is changed by executions of SPED(64)
with different frequency settings.
The following diagram shows the frequency of pulse outputs from port 1 as
the program is executed.
!Caution Be sure that the pulse frequency is within the motor’s self-starting frequency
range when starting and stopping the motor.
Note Speed control timing will be accurate when frequency changes are performed
as input interrupt processes.

When IR 05000 turns ON, PULS(65) sets port 1 for 10,000
CW pulses.
Starts pulse output from port 1 at 1,000 Hz in Independent
Mode.
When IR 00000 turns ON, the pulse frequency from port 1
is changed to 1,500 Hz.
When IR 00001 turns ON, the pulse frequency from port 1
is changed to 1,000 Hz.
When IR 00002 turns ON, the pulse frequency from port 1
is changed to 500 Hz.
