Stepper Drives Support Extended Range Of Protocols

Applied Motion Products’ STF stepper drives support a range of industrial Ethernet and Fieldbus network protocols including EtherCAT, EtherNet/IP, CANopen, Modbus, Ethernet and RS-485, as well as a proprietary Serial Command Language (SCL) for communications over Ethernet (UDP or TCP) and RS-485. The steppers promise to simplify the programming by consolidating motion control functions into the application software of the primary logic or machine controller, rather than in individual axes.

 

The drives also run stored programs created with the company’s Q Programming language, which provides a range of motion profiles, multi-tasking, math functions, conditional processing, and data register manipulation in a text-based programming language. Operators can configure drives and create Q programs using STF Configurator software, available as a free download.

Digi IX20 Secure LTE Router Available for Immediate Shipment from Digi-Key

The IX20 rugged, secure LTE router is a great choice for applications from basic connectivity to industrial-class and security solutions. Its high-performance architecture gives primary and backup WWAN over software selectable multi-carrier LTE.

 

Designed to work with a range of two-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. 

 

Three power ratings are available:

  1. STF03: 12 to 48 VDC input, up to 3.0 A/phase (peak-of-sine) current output.  Lowest power of the series; ideal for smaller motors starting at NEMA 8 frame size.
  2. STF06: 12 to 48 VDC input, up to a 6.0A/phase (peak-of-sine) current output.  Mid-range power within the series.
  3. 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. For more information, checkout the STF Stepper Drive datasheets, and call 800-525-1609.
