Description

The EB-116 is a single hoard, comprehensive instructional module designed to teach basic concepts of position sensors to technology students.

The module can be operated as a stand-alone unit or integrated to the EB-2000 Computer Managed Laboratory.

Objectives

• Be familiar with the stepper motor in general

• Be familiar with the permanent magnet stepper motor and its driving modes

• Understand digital encoders operation

• Understand the absolute encoder operation. Use the GRAY code and to convert a word from the GRAY code to the binary code

• Be able to use a digital comparator

• Understanding of the digital comparator INPUT/OUTPUT characteristics

• Understand closed loop control operation of stepper motor

• Set up and operate a closed loop digital position control system capable

• of setting the stepper motor to any selected position

• Understand the operation of a digital to analog converter and of an analog comparator

• Set up and operate a closed loop analog position control system and

• compare its performance with that of digital control systems

• Be familiar with a typical hall effect transducer and with a hall effect incremental encoder

• Understand the use of a binary UP/DOWN counter in configuration with a Hall effect incremental encoder

• Be able to control the position of the stepper motor with the aid of an analog or digital comparator operating in a closed loop control

• Utilize incremental encoder and UP/DOWN counter in a closed loop position control system

• Be able to detect faults in a position sensor system
