Description - MM2000 Motion Controller
The MotionMaster 2000 is "state-of-the-art" technology with two 16-bit
microcontrollers and sophisticated internal software to achieve high-
speed intelligent positioning. Its capabilities range from simple point to
point positioning to elaborate tasks which require multiaxis coordination
and velocity and position change 'on the fly'.
The MM2000 is command driven. With a host computer, the user sends
commands that direct it to carry out typical operations in a motion con-
trol system. For example, included in its command set, there are com-
mands which tell the MM2000 the distance, the direction, the speed, and
the acceleration of the next move, and which direct it to send system sta-
tus information, typically the position as the move progresses, whether
the move is complete or in progress, and whether an error has occurred.
The MM2000 can be set up to interrupt the users host computer when a
move is complete or any error or unexpected event occurs. This will great-
ly improve the user's execution speeds and processing power because
their host computer is free to execute other tasks during a typical move
and still know exactly when the move is complete...so that the next one
can be initiated, for example.
The MM2000 provides 25,000 bytes of non-volatile memory for
program/parameter storage. Sophisticated motions control programs with
"IF...THEN" and "WHILE ... WEND" statements, which test the logical levels
of 8 I/O bits, can be created. Also system configurations and options such
as velocity, acceleration, software limits, and PID compensation parame-
ters are retained during power off and automatically reloaded at power on.
The MM2000 features encoder counting circuitry and commands that
enable the user to read the position of the system at any instant of time.
The encoder required is an incremental encoder with TTL compatible
quadrature outputs.
The MM2000 can be directed to find a home position defined by either the
location of a switch or the position where its internal position counter is
zero. It also monitors plus and minus direction limits inputs to protect the
user's system from damage.
The MM2000 features an elaborate command interpreter and system moni-
tor. Every command received is analyzed for the correct format. If the
command format is incorrect, the MM2000 will not execute the command
and will store a descriptive error message in its output buffer.
Description - ESP6000 Motion Controller
The Enhanced System Performance (ESP) architecture consists of the
ESP6000 controller card, UniDrive6000 universal motor driver, and ESP-
compatible stages. The ESP6000 controller card is designed for convenient
installation in the user's own PC.
The ESP6000's Windows-based setup utility provides a full range of func-
tions for configuring and operating from one to six axes.
The system is designed to operate with Newport Corporation's ESP-com-
patible stages, but can be configured to function with other stages.
