Zoom
- MCX314As is a multi-axis motion control IC.
- This IC can connect up to 4 axes of either stepper motors or servo motors for position, speed, and interpolation control.
- Action management function is included so that host CPU will not be interfered during the driving.

  • Independently control each axis
  • Built-in inear and circular interpolations function
  • Built-in S-shape and trapezoidal speed acceleration/deceleration function
  • No interference with host CPU, while processing interpolations
  • Encoder feedback included
  • Maximum speed: 4MPPS 
Axial Control 4 independent axis
Data Bus 16 or 8 bits
Interpolation

Linear Interpolation -- any 2 / 3 of 4 axes
Range : -2,147,483,646 ~ +2,147,483,646
Accuracy : ±0.5 LSB; Speed: 1PPS ~ 4MPPS

Circular Interpolation -- any 2 of 4 axes
Range : -2,147,483,646 ~ +2,147,483,646
Accuracy : ±1 LSB; Speed: 1PPS ~ 4MPPS Bit

Interpolation -- any 2 / 3 of 4 axes, for CPU calculation
Continuous Interpolation : performing linear and circular interpolations continually
Highest drive speed of continuous interpolation : 2MHz
Other functions : interpolating axes selection, constant surface speed control, interpolating steps performance
