*IMPORTANT* Our products sold through eBay are more expensive than our standard list price. This is because the eBay price includes shipping as well as eBay seller fees and promoted listing fees. eBay applies seller fees and promoted listing fees to not only the selling price, but also to the shipping and to any sales tax collected eBay collects from the sale. The eBay price is adjusted so that after eBay deducts these fees we receive the same proceeds from the sale as if we sold the item directly. At the end of the day you have a choice where you buy our products from and can choose the marketplace that best suits you.

Advanced Control Algorithms
- Supports modified PI-D (PIV) algorithm.
- 32 bit ARM CPU with double precision floating point motion calculations.
- Command smoothing for smoother and quieter operation.
- Velocity and acceleration feed-forward for higher accuracy trajectory tracking.
- Stiction (static friction) compensation reduces positioning errors on move starts and stops.
- Supports all combinations of metric and imperial hardware.
- Automatic calculation of electronic gearing and step multiplying with no loss of precision.
- Abnormal condition detection like following error and encoder faults.
- Real-time statistical motor position error analysis over multiple timeframes.
Easy Setup and Operation
- Standard isolated PUL/DIR/ENA/ALM interface supports popular CNC software and controllers.
- Supports CNC controllers from 3VDC to 30VDC without needing series resistors.
- Flexible wall or base mounting “L” chassis open frame design.
