NEMA11 RS485 Stepper Motor Driver / Integrated Stepper Motor (AR11)
Product Link
[edit]Description
[edit]The NEMA11 RS485 Stepper Motor Driver (AR11) is a compact stepper drive solution supporting RS485 communication. It is available as a standalone driver or as an integrated stepper motor, providing flexibility for various system architectures.
The AR11 supports standard MODBUS-RTU protocol over RS485, enabling easy integration with PLCs, HMIs, and industrial controllers. The driver uses advanced 32-bit DSP technology for smooth current control and low noise operation.
With daisy-chain capability via RS485, multiple AR11 drives can be networked on a single bus, significantly reducing wiring in multi-axis applications. Each axis can be individually addressed and controlled.
