Geckodrive G540 4-Axis Digital Stepper Motor Driver

• Geckodrive G210X 4-Axis Digital Stepper Motor Driver
• Is a variation of the G201X and is designed to run a large stepper motor
• Features CPLD design
• Runs a stepper motor up to 7A and 80VDC

The Geckodrive G210X 4-Axis Digital Stepper Motor Driver 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. Its 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. The step pulse multiplier board, the G901X, has four resolution options: Full step (200 PPR), half step (400 PPR), five microstep (1000 PPR), and ten microstep (2000 PPR).

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.
