485 Bus Type Open and Closed Loop Step/stepper/stepping Motor Driver
RSA57E
1.1 Product Overview
485 bus type open and closed loop stepping driver is the latest digital hybrid stepping servo driver with serial debugging function, integrated MODBUS-RTU standard protocol specification, the communication network port adopts the standard RJ45 interface, the user can set up subdivision, current, speed, working mode and other parameters through the upper computer debugging software, which greatly enriches the practical functions of the product and can meet the needs of most occasions. It can meet the application needs of most occasions.
The 485-bus open and closed-loop stepping driver adopts servo-like control principle, compatible with the double advantages of open-loop stepping and servo system, and adopts the latest 32-bit DSP control technology, which greatly improves the performance of the stepping system. It has excellent smoothness and ultra-low noise in both medium and low speeds, and the high-speed torque has been greatly improved, which extends the speed application range of the stepping motor. The smooth and precise pure sinusoidal current vector control technology effectively reduces the motor heat, and its strong compatibility and high cost performance can meet the application of most occasions.
1.2 Product Features
New generation 32-bit DSP technology, good smoothness, strong compatibility and high cost performance.
Support open and closed loop mode switching

Current, locking current, subdivision, PI and other parameters can be set and queried through the master station.
Adopts RS485 bus with isolation and supports standard MODBUS-RTU protocol.
Dial code SW1-5 to set the communication address of the driver, which can support 32 devices, and more can be set through the master station.
11-channel opto-isolated programmable input interface, receiving external control signals, realizing drive enable, start-stop, limit and other functions.
5-channel opto-isolated programmable output interface, output drive status and control signals, such as alarm, in place, return to home completion and other functions.
Built-in microfine division, excellent low-speed smoothness.
Over-current, over-voltage, under-voltage, phase loss, over-difference and other protection functions.
Pure sinusoidal current vector control effectively reduces motor heat generation.
AC/DC universal, voltage range: AC20~50V/DC24V~70V.
1.3 Applications
Suitable for all kinds of small and medium-sized automation equipments and instruments, such as engraving machine, marking machine, cutting machine, plotter, CNC machine tool, automatic assembly equipment, etc. The application effect is excellent in the application of the equipment where the user expects small noise and high speed.
