Program example
[Operation content]
1. Pulse output from the specified channel ch0 begins at 1,000 Hz when the F174
(SP0H)
instruction execution condition (trigger) R10 goes on.
2. At the point when 1,000 pulses have been counted at a frequency of 1,000 Hz, the
frequency switches to 2,500 Hz.
3. At the point when 3,000 pulses have been counted at a frequency of 2,500 Hz, the
frequency switches to 5,000 Hz.
4. At the point when 8,000 pulses have been counted at a frequency of 5,000 Hz, the
frequency switches to 1,000 Hz.
5. At the point when 10,000 pulses have been counted, pulse output stops.

When the execution condition (trigger) R10 of the F174 (SP0H) instruction goes on, the
high−speed counter control flag R903A (R903C) goes on. When the elapsed value
reaches 10,000 and pulse output stops, R903A (R903C) goes off.
Note: With FP−X, refer to the table of areas used for the internal relay equivalent to
R903A (R903C).
[Settings and program]
The frequency range is from 191 Hz to 100 kHz, the duty 1/4 (25%), the operation mode
is Incremental, and the output method is CW.
