When the RAMP instruction input is on, pulses are output according to the settings configured by the control registers. The
reversible control signal is output from Q16 or Q12. When pulse output starts, M50 turns on. M52 turns on while the pulse
frequency is increasing or decreasing. The pulses increase according to the frequency change time every 10 ms until they reach
the steady pulse frequency (from the initial pulse frequency). When the configured number of pulses are output, the pulses stop.
In this situation, M50 turns off and M51 turns on.
If the RAMP instruction input turns off during pulse output, pulse output is canceled. If this input turns on again, the operation
starts from the beginning. Even if the contents of the data registers are changed during pulse output, the change is not reflected
in the pulse output operation. The changed content is reflected the next time the RAMP instruction is started.
The changes from the initialization input are not reflected while the RAMP1 instruction input is on. If you wish to initialize the data
registers with the initialization input, turn the initialization input on after turning off the input.
