STF Field-bus Control Stepper Drives from MOONS' Industries
MOONS' has introduced a new series of stepper drives that support a variety of Industrial Ethernet and Fieldbus network protocols, including EtherCAT, EtherNet/IP, CANopen, Modbus, Ethernet, and RS-485, and a proprietary Serial Command Language (SCL) to facilitate efficient network communications over Ethernet (UDP or TCP) and RS-485. STF Stepper Drives provide system designers and machine builders with the flexibility of controlling step motors using a network protocol of their choice by accepting high-level commands via a network connection. These advanced stepper drives simplify the programming by consolidating motion control functions into the application software of the primary logic or machine controller, rather than in individual axes. These DC-powered micro-stepping drives also run stored programs created with Q Programming language. Q Programming provides a range of motion profiles, multi-tasking, math functions, conditional processing, data register manipulation, and more in a robust yet simple, text-based programming language. Operators can configure drives and create Q programs using STF Configurator software available as a free download from MOONS' website. Designed to work with a range of 2-phase step motors, STF Stepper Drives offer advanced current control with an anti-resonance algorithm that electronically dampens motor and system resonances to improve motor smoothness and maximize torque over a wide speed range. Torque ripple smoothing decreases motor noise and vibrations. With STF Stepper Drives, step motors perform faster, quieter, smoother, and more accurately for today's high-speed machine and process applications. 
MOONS' offers the STF Stepper Drives in three power ratings: • STF03: 12 to 48 VDC input, up to 3.0 A/phase (peak-of-sine) current output. Lowest power of the series; suitable for smaller motors starting at NEMA 8 frame size. • STF06: 12 to 48 VDC input, up to a 6.0A/phase (peak-of-sine) current output. Mid-range power within the series. • STF10: 24 to 70 VDC input power, up to a 10.0 A/phase (peak-of-sine) current output. Highest power for largest step motors including high torque NEMA 34 frame size. All STF Stepper Drives feature two communication ports (dual-port) for daisy-chain connections of multiple drives to the central processor, HMI, or PLC.
