The Motion Mind DC Motor Controller is capable of controlling
one brushed DC motor. A variety of control methods are supported including
open loop and closed loop control. Open loop control methods do not require
feedback from an encoder and can operate with serial data input, button
presses, analogue control signals (0-5V), and pulse control from a hobby
R/C type control signal (1-2ms pulses, approximately every 20ms). Closed
control requires either a quadrature encoder (2 or 3 channel) or an analogue
feedback signal (0-5V). When operating in closed loop control modes, position
and/or velocity control are possible. Some limit switch functionality is
supported through negative and positive limit switch inputs. The state of
the index input from a three-channel encoder can be monitored and the approximate
position of the last index pulse present is available.
In addition to
a variety of control techniques the Motion Mind module has numerous communication
settings available to the user. A high-speed binary communication protocol
is implemented with an external jumper determining the baud rate (19.2KBPS
or 9.6KBPS). The binary communication protocol may be replaced with a simpler
ASCII command set through an external jumper. The ASCII protocol ensures
ease of programming with simple terminal programs and also operates at both
baud rates. Electrically the Motion Mind can communicate at RS232 levels
through an on-board translator IC, or through a TTL serial interface with
an open-collector output that allows multiple modules to share the same
data bus.
The board measures 2.4” wide x 3.6” long x 0.6” tall. The Module is powered
directly off of the motor voltage and may provide 200mA of regulated 5VDC
voltage to other off board devices.
