MPG1020 Two Axis Pulse Generator Chip, Ultra
High Speed |
 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)
