Function
Ladder example of ramp-up/down control
When start switch 0000 is set to ON, output 0502 starts to output 100,000 pulses
with a startup frequency of 500 Hz, operating frequency of 10 kHz, and acceleration/
deceleration time of 3 seconds.
When input 0001 is set to ON, pulse output is decelerated and stopped.
When input 0002 is set to ON, pulse output is immediately stopped.

Set the input time constant of input
0002 to 10 µs.
Set each parameter, and start pulse
output at the same time.
Decelerate and stop pulse output.
Perform emergency stop processing
by using an interrupt program.
