5.1 Outline of Positioning Control
This section describes the outline of positioning control.
5.1.1 Ramp-up/down Control
The Visual KV Series can directly output clock pulses not affected by the scan time
to output relay 0502.
If the frequency, the number of output pulses, and the acceleration time of the clock
pulses have been preliminarily set to data memories, the Visual KV Series automati-
cally performs ramp-up/down control.
The ramp-up/down control output function offers ramp-up/down timing charts of the
startup frequency, operating frequency, acceleration time, and deceleration time as
shown below.
The output frequency can be set within the range of 200 to 50,000 Hz.
By using the ramp-up/down control output function, ramp-up/down control of step-
ping motors and AC servo motors (pulse input types) is possible.
