Function
Pulse output number:
H01 to H04
Change specification:
H00: Sets the frequency value and
number of pulse output,
H01: Sets the frequency value
only,
H02: Sets the number of pulse
output
Frequency: 10 to 5000 (Hz)
* The maximum frequency of 5000 Hz represents the total of
all pulse output frequencies.
* If the frequency value is set to less than 10 Hz, it is
internally changed to 10 Hz. The S parameter is also
rewritten.
Number of output pulses: H0000 – HFFFF (0 to 65535)
Auto correction is executed when the value corresponding to
the CPU model is specified in WRF06B.
Caution: There will be a slight error even if correction setting
is performed.
•
Pulse output is commenced at the specified frequency. Output is stopped once the number of pulses specified have been
output.
•
Sets the frequency value in Hz.
Example: To set a frequency of 3 kHz, set 3000 (HBB8) as internal output.
•
Sets the count for the number of output pulses.
Example: To set output of 10,000, set 10,000 (H2710) as internal output.
