1 Overview
1.1 Product Introduction
RS485 Bus driver of Modle Bus Standard introduced by our company. It adopts the latest
32-bit DSP digital processing technology. The driver control algorithm adopts advanced
variable current technology and advanced frequency conversion technology. The driver
generates less heat and them or vibrates less,smooth operation.The user can set any IDaddres
swithin 1-255 and any current value within the rated current, which can meet the needs of
most applications. The bus driver can drive two-phase open-loop stepper motor, three-phase
open-loop stepper motor, hybrid servo motor, brushless DC servo motor, etc... Due to the use
of built-in micro-subdivision technology, even in the conditions of low subdivision, but
also can achieve high subdivision effect, low, medium and high-speed operation is very
smooth, ultra-low noise. The auto-tuning functionis integrated in the driver, which can
automatically generate the optimal operating parameters for different motors and maximize
the performance of the motors.
