The
Smart MotorTM from Animatics
This line of products provides a
much broader solution to a machine designer and builder than any other
stepper or servo product in the industry. The SmartMotor™ is literally a
“black box” solution to motion and in many cases “machine” control
with its internal encoder, amplifier and controller. With its BASIC
programmability and expansive I/O, the SmartMotor™ can in the best cases
replace a cabinet full of controllers, amplifiers and PLCs. While the
SmartMotor™ is very competitive with other solutions, it can pay for
itself several times over because it is so much easier to service,
especially from remote locations. Anyone who can turn a screwdriver can
replace a machine's entire control system. What’s more, such an occasion
is far less likely because the SmartMotor™ solution has no inter-system
cables to fail. Fewer components (especially fewer cables) maximize the
SmartMotor™ MTBF and make it a favorite for machine builders all
over the world.

What You Can Do With A Smart Motor.
Torque and Velocity
Control Because of the SmartMotor’s low cost, it is an excellent choice
even for simple torque or velocity control. In Torque Mode, the SmartMotor™
is a source for highly controllable continuous torque, completely
independent of position. In Velocity Mode, velocity is held to within a
fraction of a percent, and velocity, acceleration, and deceleration can be
modified on the fly.
Device Connectivity
The SmartMotor™ has internal Analog and Digital I/O, and can also make
use of the AniLink port to provide access to extended I/O. In the future,
we will also offer Ethernet and Fieldbus extensibility. For
communications, the SmartMotor™ offers RS-232, AniLink (proprietary),
and RS-485 protocols.
Stepper Replacement / Substitution
Throughput on machines using traditional stepper (or microstepper) motors
can be dramatically increased by replacing existing stepper axes with
SmartMotors™. The traditional drive-amplifier combination can be
seamlessly replaced by routing step and direction signals from the
existing motion indexing system directly to the SmartMotor™. No hardware
or software changes are required, save for user-specified increases in
speed allowed by the superior high-speed performance characteristic of
servomotors.
Multi-Node Networking
Multiple axes of SmartMotors™ (up to 100) can be networked together
(using RS-485 adapters), but without the usual hassle of encoder and drive
cables. Additionally, all home and limit sensors can be connected directly
to the motors themselves, so cabling is reduced to an unprecedented level
of simplicity.
Encoder Following
The SmartMotor™ will follow an external encoder with virtually any
gearing ratio. This ratio is set in software. While the motor is
performing electronic gearing, it can also run its internal program
interpreter, and talk to peripherals.
Alternatively, an external encoder can be used to increment and decrement
the internal 32-Bit counter, for later use within the application program.
Intelligent Communications
Use the SmartMotor's second RS-485 port to talk to intelligent peripherals
like MFCs, light curtains, bar code readers, absolute encoders or even
other SmartMotors™. Once baud rate, bit, and parity parameters have been
set properly, the SmartMotors™ can communicate with virtually any
serially addressable device!
Cam Following
Load a cam table for high speed cam following with interpolation between
table entries.
Battery Operation
Because the electronics within the SmartMotor™ are CMOS and the
amplifier is extremely efficient, it is also an excellent choice for
battery or remote operation.
Application Development Using SMI
All SmartMotors™ come with a terminal program, a program editor, and a
source level debugger. These can be loaded from CD-ROM, or simply
downloaded via the Internet. Simply write your program, test it and
download it to the SmartMotor™. Either reset or re-power your SmartMotor™
and watch your program go to work. System parameters can be monitored and
modified in real time, all from one screen. This Windows interface comes
with source code to a variety of different host and embedded applications
in both BASIC and C.
