When the pulse train is input from
terminal JOG, the number of sampled
pulses can be converted.
The result of conversion is stored to
SD1236.

Desired values can be set.
Because devices D206 to D255 used by the PLC function
can be mutually accessed, the values set to Pr. 1150 to Pr.
1199 can be used by the sequence program. The result of
performing calculation by a sequence program can also
be monitored by Pr. 1150 to Pr. 1199.
