Target value 4: 2,000 pulses
When the execution condition R10 goes on, pulses are output from Y0 at a frequency
of 1,000 Hz, and positioning begins.
At the point when 1,000 pulses have been counted, the frequency switches to 2,500
Hz. Positioning is then carried out sequentially in accordance with the values of the data
table, until it stops at the data table containing the pulse output stop value (K0).
When the program is run, the data table and pulse output diagram are as shown below.
