The ICON Position Controller has been designed to work seamlessly with
the ICON H-Bridge module. When used with a brushed DC motor and a quadrature
encoder, the ICON Position Controller and ICON H-Bridge form a highly versatile,
low-cost, position control module, for medium and low current servo motor
control.
The ICON Position Controller circuitry includes a switching step-down
regulator, 10-bit analogue-to-digital conversion, indicator LEDs, quadrature
decoder circuitry, and two channels of 10-bit PWM generation.
The ICON Position Controller has four primary modes of operation. The
first, Direct Position control mode allows a master unit to command the
desired motor position up to 32 bits in length (two's compliment). In this
mode of operation acceleration and maximum velocity are determined by the
programmed PID filter values.
In Trapezoidal control mode the ICON Position Controller may be configured
to run up to 16 consecutive trapezoidal movement segments. Each segment
can be programmed with the desired position, acceleration limit, velocity
limit, PID update rate, error-band, dwell time, and one of three user configurable
PID filter settings. A master unit may initiate the trapezoidal movement
segments, or the ICON Position Controller may be programmed to implement
the movements on power up.
Analogue input (0V-4.096V, 1024 steps) control mode, with offset and
multiplier settings can allow limited position control with just a potentiometer
or other analogue source.
Velocity control mode, with configurable rate of change and update rate
settings make, the ICON Position Controller a useful platform for PID based
motor speed control.
Additional features such as data logging (for direct and trapezoidal
control modes) and user configurable limit switch settings round out this
versatile and cost-effective position control solution. Support products
including free programming/test software, the ICON Serial Adapter (simplifies
connectivity to a PC), and the ICON H-Bridge Active Cooling Kit make implementation
of designs using these components painless and simple.
The unit measures 4.0" x 1.9" x 0.6". Motor connections are made via
a screw terminal.
