MPG2031 , 2 Axis Pulse Generator Chip |
 Description
This Pulse Generator chip introduces one of Mycom’s new developments
in Motion Control technology. The MPG2031 Pulse Generator chip is a DSP type
peripheral circuit with built-in functions for Motion Control applications. The
MPG2031 can control 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 S-Curve, Trapezoidal as well as
complex move profiles for Closed loop or Open loop applications.
Features
- Single Chip to operate two Axes of Motion Control for Stepping or
Digital Input Servo Motors.
- Capable of modify the Acceleration and Deceleration rates in order to
provide S-Curve, Trapezoidal and complex move profiles for Linear or
Circular Interpolated movements.
- Ultra High Speed Pulse Rate output up to 2.0 Mhz.
- Multi-Axes Synchronous Start functions.
- Starting point for Deceleration can be calculated automatically or two
modes of Manual functions can be used for Deceleration definitions.
- Three Modes for Home Position searching is provided.
- Encoder Counters are provided with Encoder scaling factors of 1 , 2 or 4
times the Input count.
- Six Interrupts are provide for system or user intervention.
