Abstract

RS485 based multi axis motor driver/controller has been developed around LMD18245. This system is developed keeping in mind varying requirements of the users for various applications i.e. from single axis to multiple axes with current rating of 200 mA to 3 Amp. The required current may be set in 16 discrete levels. Single card with all the hardware space for controller as well as driver has been designed. Depending on the use, hardware may be put on it. A system containing one controller and 4 stepper motor drives have been tested. All the cards are communicating over RS485 bus. The system is successfully used for magnetic field mapping of sample magnets received from the supplier before final delivery.
