G201X Digital Step Drive

The G201X is designed to run a large stepper motor efficiently and inexpensively. This is made possible due to its CPLD design, which moves most formerly analog operations to firmware while still maintaining its large dual H-bridge power section. It’s oversized MOSFETs can run a stepper motor up to 7A and 80VDC without issue, pushing its motor range to NEMA 17 through 42.

Easy to use features like a DIP switch for user settings (from current setting to resonance compensation), indicator LEDs for fast diagnosis of proper function, and a universal COMMON input makes for a simple to set up and powerful package.

At a native ten microstep resolution the G201X does not require extremely high input frequencies to operate at high speed but offers enough resolution to match the accuracy of most stepper motors (+/- 5% of one full step). An adjustable low speed smoothness trimpot compensates for motor nonlinearity at the low end while midband resonance compensation ensures reliable torque output through the midband dropout region.

Full Step Morphing is entirely unique to Geckodrive products and can transition your motor to a true full step motor between 4 – 6 revolutions per second. No software changes are required to take advantage of this and accuracy will not be sacrificed. This results in a 30% increase in useable torque over a drive that does not morph.

The G201X is a pin-for-pin drop-in replacement for our legacy G201, our first stepper motor control.

All Geckodrive motor controls come with our industry leading three-year warranty and free US based technical support. Should a drive sustain damage in the field we offer repairs to minimize your downtime. If you are unsatisfied with your purchase we offer a 90 day return window.
