R57 2-Phase Open Loop Stepper Driver FAQs

Straight answers to what buyers ask us most about 2-Phase Open Loop Stepper Driver.

The R57 is a 2-phase open loop stepper driver from Rtelligent for two-phase stepper motors with a base below 57mm. It runs on a 32-bit DSP platform with built-in micro-stepping and automatic parameter tuning, giving low noise, low vibration, low heating and high torque at higher speeds. The recommended supply is 36V or 48V DC within its 18-50V DC input range.

The R57 delivers up to 5.0A peak, or 3.5A RMS. SW1 to SW3 give eight current steps starting at 1.0A peak (0.7A RMS), so the output can be matched to the rated current of your motor. Pulses per revolution are set with SW5 to SW8, from 400 to 25600, and any subdivision can be set through the debugging software when all four switches are on.

The R57 is used on engraving machines, marking machines, cutting machines, plotters, lasers and automatic assembly equipment where a mid-size stepper motor drives the axis. Its PUL and DIR inputs accept 3.3-24V signals, so it can take commands directly from a PLC without a series resistor, which simplifies wiring on retrofit and new machines alike.

R57 pricing depends on the quantity you order and on whether you need the driver on its own or as a set with a matching motor below 57mm. RB Automation prepares each quotation to your requirement rather than listing a fixed rate. Call +91 8511104864 or send your details through the inquiry form on this page to receive a quote.

You can buy the R57 from RB Automation, an industrial automation supplier in Ahmedabad, Gujarat, that supplies customers across India. RB Automation is an authorised technical partner of Rtelligent. Email contact@rbautomate.com or WhatsApp +91 9898739737 with the quantity and your motor details, and the team will confirm availability and send a quotation.

Yes. Share your motor frame size, rated current and supply voltage, and RB Automation will confirm whether the R57, with its 5.0A peak limit and support for motors below 57mm, fits your axis or whether a higher-current driver is needed. Checking this before ordering helps you avoid an undersized drive. Call +91 8511104864 for selection help.
