RoHS compliant microstepping driver

STEP motor specialist Lin Engineering has introduced the RoHS compliant version of its 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 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 utilise a 12-24V dc 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.

Other features include:

* The ability to recognise 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.
