status
When the RAMP instruction input is on, pulses are output according to the settings configured by the control registers. M0050
turns on during pulse output. M0052 turns on or off while increasing or decreasing the pulse frequency. Pulses are output
according to the frequency change time, until they reach the steady pulse frequency (from the initial pulse frequency). When the
frequency change time is specified as 100, the steady pulse frequency is reached in 100 ms by increasing or decreasing the
frequency every 10 ms. Pulse output stops when the pulses configured by the preset value are output. (The number of pulses is
also counted while changing the frequency.) At this time, M0050 turns off and M0051 turns on.
If the RAMP instruction input turns off during pulse output, pulse output is canceled. If the RAMP instruction input turns on again,
the pulse count is reset and pulse counting starts. Even if the contents of the control 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
executed.
