Item Details

MCX314As is a cost-effective high performance motion control IC designed for stepper motor or pulse type servo drivers with position, velocity and interpolation controls. This intelligent single chip offers s-curve/trapezoidal acceleration/deceleration, target position and velocity changes on the fly, built-in 32bit linear/circular interpolation control, automatic home search and built-in integral type filter. Every function of the MCX314As is controlled by specific registers, which are command registers, data registers, status registers and mode registers.

  • Independent control of 4-axes
  • Supports linear and bit pattern interpolation for any 2 or 3 axes
  • Supports CW/CCW circular interpolation for any 2 axes
  • Continuous interpolation to execute a series of interpolation processes, linear interpolation - circular interpolation - linear interpolation - …
  • S-curve, trapezoidal or velocity contouring
  • Triangle form prevention of linear/s-curve acceleration fixed pulse driving
  • On the fly target position and velocity changes
  • Maximum speed: 4MPPS, available for constant speed, linear/s-curve acceleration/deceleration driving
  • Supports automatic deceleration including for non-symmetrical trapezoidal acceleration/deceleration driving
  • Supports automatic home search that high-speed near home search - low-speed home search - encoder Z-phase search - offset drive
  • Supports synchronous action, which performs any action from the factor of own axis to other axes
  • Built-in integral type filter, selectable to enable or pass a signal through, and time constant from 8 types
  • Selectable independent 2 pulse or 1 pulse/direction system
  • 32-bit compare registers for each axis, can be used as software limit
  • Read out of drive status by registers
  • Selectable encoder input mode, quadrature or up/down pulse input
  • Emergency stop input for all axes
  • Connectable CMOS, TTL
  • 144-pin LQFP package 5V operation
