Product Introduction
RS-485 ST68D is our new ModBus standard RS485 bus open loop stepper driver, which adopts the latest 32-bit DSP digital processing technology.The user can set any ID address within 1-255 and any current value in the rated current to meet the application needs in most occasions. The driver integrates the parameter auto-tuning function, which can automatically generate optimal operating parameters for different motors to maximize the performance of the motor.
