Programmable T/S-curve Acceleration and Deceleration
Each of four axes can be preset individually with S-curve or trapezoidal
acceleration/deceleration rates. When using S-curve acceleration to con-
trol driving speed, output pulse is generated in parabolic-shaped accelera-
tion or deceleration curves, and the triangular curve phenomenon will not
occur through the NOVA MCX314AS-motion ASIC design concept.
Linear and Circular Interpolation
Any two or three axes can be selected to execute linear interpolation driv-
ing and any two axes can be selected to execute circular arc interpolation
control. The interpolation speed range is from 1 PPS to 4 MPPS.
Powerful Position Management Function
Each axis is equipped with a 32-bit logical position counter and a 32-bit
real position counter. The logical position counter counts the axis’ pulse
output number and the real position counter is recorded with the feedback
pulse from the outside encoder or linear scale.
Speed Control
The speed range of the pulse output is from 1PPS to 4MPPS for constant
speed, trapezoidal or S-curve acceleration/deceleration driving. The
accuracy of the frequency of the pulse output is less than +/- 0.1% (at
CLK=16 MHz). The speed of driving pulse output can be freely changed
during the driving.
Bit Pattern Interpolation
Any 2 or 3 axes can be selected to perform the bit pattern interpolation,
and the interpolation data is calculated by CPU; CPU writes the bit data
into MCX314AS. Then, MCX314AS outputs pulses continuously at the
preset driving speed. So, the user can process any interpolation curve by
this mode.
Continuous Interpolation
Different interpolation methods can be used continuously, for example:
Linear interpolation
Æ Circular interpolation Æ Linear interpolation.
The maximum driving speed of performing continuous interpolation is 2
MPPS.
