The G250 has a 2x15 pin connector, while the G251 has a 12 pin connector both operate exactly the same as a miniature G201X. The G250 and G251 do not have short circuit protection. If your motor is below 3.5A, you can use the above drives as well as the G250, G251 or G540 drives. To understand the benefits of the step multiplier and step morphing please see Morphing/Micro-Stepping tab.Īs a general guideline first determine the maximum step pulse frequency of your step pulse source (CNC program, PLC, etc.) if it is below 25 kHz, we recommend using a step pulse multiplier equipped drive, such as the G210X or G213V.If your step pulse frequency is above 25 kHz, and you do not need the benefits of step multiplier/morphing enhancement, then you can use a G203V or the G201X.

The step multiplier enhanced drive offers the same specifications as the base drive and adds the choice of full step, half step, 5 micro-steps and 10 micro-steps. The G210X is a G201X with a built in step pulse multiplier, similarly the G213V is a G203V with a built in step multiplier. For hobbyist and those not familiar with wiring up stepper drives and motors we recommend the fully protected drives. When connected correctly and in a safe and clean environment, the G201X and G210X will function identically to the G203V and G213V respectively. The G203V and G213V drives offer short circuit protection as well as many other protections against the most common failures. For motors up to 3.5A your options are the G250, G251, and the G540.įor motors up to 7A, the high current drives are available in both a fully protected version and a lower cost version. For motors up to 7A, your drive options are the G201X, G210X, G203V, and G213V.
They are divided into two main types: the high current drives which go up to 7A, and low current drives which go up to 3.5A. Gecko currently offers seven stepper motor drives.
