Introl DC100A Series of Brushless Motor
Controllers
The Introl DC100 series was designed, developed and is manufactured by Introl
Design, Inc. to control three phase brushless DC motors. The DC100 is ideal for
controlling general purpose brushless motors, or high performance servo motors, in tight
and responsive servo loops. This controller provides all the advantages of DC brush type
motors without the maintenance associated with brushes. Hall effect sensors supply
commutation information, while encoder feedback supplies velocity information. Set-up
requirements are easy to understand potentiometer adjustments. Isolated control circuitry
allows quick and easy interface to other equipment without the requirement of isolation
transformers or other isolation circuitry. Indicators include power on, run, current
limit, fault, and bus voltage. The DC100 has been designed as a low cost, high performance
alternative to brush type controls or expensive servo systems, up to 1 1/2 hp DC. (Larger
models will be available soon.) This controller is protected against undervoltage,
overvoltage, and overcurrent. Applications for the DC100 include indexing, positioning,
synchronizing, precision speed control, spindle drives, and many others. |
| Length Control Option: The length control card mounts
internal to the DC100 drive, adding 1 inch to the width, converting it to a stand alone
single axis controller. The length control card utilizes differential encoder inputs with
x4 logic providing 4000 counts of position resolution per motor revolution. All parameters
can be programmed on the fly, and are installed through a serial communication link with
one of Introl's Operator Interfaces, or a computer. As a stand alone, the length
controller can be programmed with a single preset, executed each time the run input is
initiated, or have one of four preset indexes selected externally. All inputs are
optoisolated, with an isolated 12 VDC supply, included as standard, for supplying power to
optoisolators. Index complete and batch complete outputs are uncommitted phototransistor
outputs. |
Operator Interface Options: Introl manufactures a variety of
operator interfaces for positioning or speed control, easily programmed and operated. The
thumbwheel and pushbutton switches with LED indicators give the operator simple but
effective local interface to process control. Any Introl interface doubles as a
programmer, eliminating additional communication equipment required to set up initial
parameters in the length controller card. Pushbutton and selector switches are rugged
industrial switches, and connected to a printed circuit board for reduced wiring.
Thumbwheel switches and LED indicators are also connected to a printed circuit board,
monitored by an on-board microcontroller, communicating information to the length
controller card through serial communication, reducing field wiring, improving noise
immunity, and reliability. |
