EDE1200 STEPPER DRIVER

For this reason be prepared to do some experimenting to get the results you want. Although the EDE is sensitive to damage from static discharge, once it is installed in its socket the IC is very safe as all of its pins are connected to the 5 volt supply or to common through low impedance paths. Also avoid carpeted areas during assembly. The board measures 1. Although the circuits are functional the pages are not meant to be full descriptions of each circuit but rather as guides for adapting them for use by others. Users of this circuit will have to determine motor phasing and power requirements for themselves. The following picture is of an assembled circuitboard for the Unipolar Stepper Motor Driver.

The explanations for the circuits on these pages cannot hope to cover every situation on every layout. If you use any of these circuit ideas, ask your parts supplier for a copy of the manufacturers data sheets for any components that you have not used before. Also avoid carpeted areas during assembly.

Circuit Boards And Parts

All functions of the EDE can be controlled by another circuit or the parallel output port of a PC with suitable characteristics. Refer to the EDE’s datasheet for some examples.

Steppee that operate at voltages lower than 12 volts can also be used with this driver but a separate supply of of 9 to 12 volts will be needed for the control portion of the circuit in addition to the low voltage supply for the motor.

These data sheets can often be found on the web site of the device manufacturers. If the circuit board is to be placed in a plastic case, do the assembly work on a wood or metal surface that is connected to earth.

When handling or assembleing the circuitboard, avoid nonconductive surfaces such as plastics or glass.

The board measures 1. A good practice is to touch the work surface before touching the circuitboard.

Users of this circuit will have to determine motor phasing and power requirements for themselves. Option 4 – The price for 1 circuit board is Power for the motors can be regulated or filtered and may range from 12 to 24 volts with currents up to 2 amps. If you are interested in printed circuit boards please send an email to the following address: Although the EDE is sensitive to damage from static discharge, once it is installed in its socket the IC is very safe as all of its pins are connected to the 5 volt supply or to common through low impedance paths.

The relative positions of the terminal blocks at the ends of the circuitboard correspond with those in the schematic diagrams. The board has a protective coating on the copper side but has been not tinned or silkscreened. The following picture is of an assembled circuitboard for the Unipolar Stepper Motor Driver. Although the circuits are functional the pages are not meant to be full descriptions of each circuit but rather as guides for adapting them for use by others.

EDE Unipolar Stepper Motor Driver

Stepper motors that require currents greater that 1 amp per ee1200 or operate on less than 12 volts can be controlled by the driver by adding external transistor to the circuit and a external power supply suitable for the motor.

These sheets contain a wealth of data and circuit design information that no electronic or print article could approach and will save time and perhaps damage to the components themselves. This is especially true of circuits such as the “Across Track Infrared Detection” circuits and any other circuit that relies on other than direct electronic inputs, such as switches.

If you have any questions or comments please send them to the email address on the Circuit Index page.

Each stepper motor will have its own power requirements and as there is a great steepper of motors available this page cannot provide information in this area. For this reason be prepared to do some experimenting to get the results you want. The circuitboard would also have to be modified.
