1  Introduction
Thank you for selecting the MOONS’STF series stepper drive. The STF series are high 
performance fieldbus control stepper drive which also integrates with built-in motion controller. The 
drives can be controlled by SCL, Modbus/RTU or CANopen in real time. Motion profiles can also 
be programmed and stored in drives (Q Program) and then be triggered by SCL, Modbus/RTU or 
CANopen commands. The drives
 support RS-485/422 or CANopen communication.
