R208 Microstepping Driver

Jan. 29, 2008
Lin Engineering, the Step Motor Specialists, are pleased to introduce the RoHS compliant version of the popular R208 Microstepping Driver.  The R208 is a cost effective solution to high priced drivers delivering uncompromising performance without the hefty price.    The R208 Driver is compact in design with low power dissipation and automatic current reduction. It is able to provide up to 2.0 Amps of phase current to any bipolar step motor. Users have the option of setting the micro stepping resolution from full step, half step, 1/4 step to 1/8 step.  The R208 drive unit is even able to utilize a 12-24 VDC power supply in order to produce constant sinusoidal current waveforms.  Additionally, the driver features optically isolated step, direction and disable inputs, built-in thermal shut down and efficient current control features.   The two newest features of the R208 are: The ability to recognize step pulses from the controller from either the rising edge or the falling edge.  This option (which is user configurable) allows for greater flexibility using the R208 with various types of PLCs.     The R208 now allows the ability to change the amount of holding current that is applied to the motor.  A cutback current of 23% is the default setting, but can now be changed to 100% of the run current via a dipswitch on the board. * Bipolar Step Motor Driver * Operates from +12 to 24 VDC * Phase current ranges from 0.35 to 2.0 Amps Peak * Selectable Step Resolution from Full, Half, 1/4, and 1/8 microsteps * Optically isolated Step, Direction, and Disable/Enable Inputs * Selectable Current Reduction of 33% * Low Power Dissipation * Efficient Current Control * Thermal Shutdown, Under-voltage Protection * Power-on Indicator * Power Disable/Enable Control * Sinusoidal current waveform * Low Cost Driver
