Features
General Description
The MC1231A is a dedicated motion processor which functions
as a complete chip-based motor controller. Packaged in a 2-IC
chipset, this device performs trajectory generation, servo loop
closure, and sinusoidal commutation. The chipset inputs
incremental encoder signals and outputs PWM or
DAC-compatible motor command signals. The MC1231A is
available in a one, or a two-axis configuration.
The MC1231A is functionally similar to other members of
PMD's 1st generation chipset family however it adds the ability
to perform sinusoidal commutation of brushless motors. All of
these devices provide sophisticated motion control capabilities
allowing the creation of complex profile sequences with very low
tracking errors.
Both two and three-phase brushless motors are supported by
the MC1231A. When used with two-phase brushless motors
each phase is separated by 90 degrees. When used with
3-phase brushless motors each phase is separated by 120
degress. The commutation angle is continuously calculated
using the encoder position. User-programmable commutation
parameters allow a very wide range of encoders and motors to
be controlled.
The chipset is controlled by a host processor which interfaces
with the chipset via an 8-bit, bi-directional port. Communications
to/from the chipset consist of packet-oriented messages.
The chipset is packaged in 2 68-pin PLCC packages. Both
chips utilize CMOS technology and are powered by 5 volts.
