PC BASED SERVO MOTOR CONTROL

JRA announces the SERVO2 PC compatible 2 axis servo motor controller.

The SERVO2 plugs into any PC compatible motherboard and independently
controls 2 motors. Feedback is provided by optical encoder on the motor
shaft.

The controller operates in two modes. In the position model the user enters
maximum motor speed in rpm and final position in encoder counts. The
controller commands and monitors the motor move to the final position. The
motor shaft will remain locked at this position until a new command is
issued. In the velocity mode the user selects motor speed and direction.
Once a start command is issued the motor will run at the command velocity
until a new command is issued. In either mode, motor velocity may be
changed during the move.

Using JRA motors the SERVO2 will accurately control speed from 0 to 2700
rpm with a position resolution of 0.17 degrees. Motor movement is smooth
and vibration free throughout the velocity range. The system is an
affordable replacement for vibration prone stepping motor systems in XY
positioning and robotic applications.

The SERVO2 software allows the user to read motor position or velocity in
real time, run motors simultaneously, create motion sequences by entering
motor velocity and destination, plot position vs time, teach moves via the
keyboard and more. Software is written in Quickbasic and program listings
are provided.

JRA offers PMDC motors, gearmotors and matching 8 amp opto-isolated PWM
type amplifiers. The SERVO2 controller is priced at $350.00 with manual
and software.
