Ramp-up/down control
When start switch 0002 is turned ON, 0500 outputs 100000 pulses under the
following conditions: start frequency 1 kHz, run frequency 5 kHz, and acceleration/
deceleration time 3 s.
Turn ON 0001 to decelerate and stop pulse output. When 0000 is turned ON, pulse
output is immediately stopped.
Application example of stepping motor control
Assume a program that can be controlled both automatically and manually.
In automatic mode, the system runs as shown in the chart below after 0000 is turned
ON.
In manual mode, the system goes forward while 0008 is ON and rearward while
0009 is ON. It returns to the origin when 0007 turns ON.
A pulse is output from 0500. Reverse the rotation direction by turning ON/OFF 0502.
The system is equipped with an origin sensor (0002), forward end limit (0006), and
rearward end limit (0004).
