MPG1020 , Motion Peripheral Chip

MPG1020 , Two Axis Pulse Generator Chip

Two Axis of Motion on a single Chip with Desolation Micro-Stepping data outputs

Ultra High Speed Pulse Generator Chip

Capable of performing Trapezoidal , Triangular as well as Velocity movement profiles

Description

The MPG1020 Pulse Generator chip is a DSP type peripheral circuit with built-in functions for Motion Control applications. The MPG1020 can control 2 Axes Stepping motors as well as Digital Input Servo motors. Address and Data commands sent directly to this Pulse Generator chip allow a system designer the flexibility of composing Trapezoidal , Triangular well as Velocity movement profiles for Open loop applications.

Features

Single Chip to Control the Motion of 2 Axes Stepping or Digital Input Servo Motors.
Capable of modify the Acceleration and Deceleration rates in order to provide Trapezoidal , Triangular and Velocity move profiles for Point to Point applications.
Ultra High Speed Pulse Rate output up to 7.5 Mhz.
Starting point for Deceleration can be calculated automatically.
Individual settings for Acceleration and Decelerations slopes.
Four Interrupts are provide for system or user intervention.
Desolation Micro-Step data output for 2-phase stepping motors (D/A transferable)
