Pulse I/O Board Section 2-2
Example 3: Using
PLS(––) to Accelerate/
Decelerate the Frequency
at the Same Rate
The following example shows PLS2(––) used to output 100,000 CW pulses
from port 1. The frequency is accelerated to 10 kHz at approximately 500 Hz/
4 ms and decelerated at the same rate.
Five seconds after the CW pulses have been output, another PLS2(––)
instruction outputs 100,000 CCW pulses with the same settings.
The following diagram shows the frequency of pulse outputs from port 1 as
the program is executed.

When IR 05000 turns ON, PLS2(−−) starts CW pulse output
from port 1.
Acceleration rate: Approx. 500 Hz/4 ms
Target frequency: 10,000 Hz
Number of pulses: 100,000
When AR 0514 (Pulse Output Completed Flag) turns ON,
a 5-second timer is started.

After 5 seconds elapses following completion of CW pulse
output, PLS2(−−) starts CCW pulse output from port 1 using
same conditions:
