6.3.1 Positioning Control (Ramp-up/down Control)
Outline of positioning control
The KV-300 CPU outputs clock pulses, independent of scan time, directly through
output relay 0500 or 0501. When the clock pulse frequency, output pulse count, and
acceleration/deceleration time are set to the data memory addresses in advance,
the KV-300 CPU automatically performs ramp-up/down control. Output frequency
can be set within the range of 153 Hz to 50000 Hz.
With this function, ramp-up/down control over stepper motors and AC servo motors
(pulse input type) becomes possible.
The following section describes setting and application of positioning control
parameters.
