STF03 - DC Advanced Microstep Drive w/ Multi Fieldbus options

Applied Motion Products

Drive part number Communications Description
STF03-R RS485
  • Dual RS-485 ports for configuration, programming, and networking connections.
  • Stream commands from a host controller to as many as 32 axes using Applied Motion's Serial Command Language (SCL).
  • Built-in support for Modbus RTU communciations.
STF03-C CANopen
  • Dual CANbus ports for operation as a slave node on CANopen networks.
  • Conforms to Can in Automation (CiA) DS301 and DS402 specifications.
  • Supports Profile Position, Profile Velocity and Homing modes, as well as the ability to run stored Q programs via Applied Motion-specific CANopen objects.
STF03-D Ethernet
  • Dual fast 10/100 Mbit Ethernet ports for configuration, programming and networking connections.
  • Stream commands from a host controller to multiple axes using Applied Motion's Serial Command Language (SCL) over Ethernet. Supports both TCP and UDP protocols.
  • Built-in support for Modbus TCP communications.
STF03-IP EtherNet/IP
  • Dual fast 10/100 Mbit Ethernet ports for configuration, programming and networking connections.
  • Designed for use on EtherNet/IP networks, the widely used industrial protocol for manufacturing automation applications.
  • With EtherNet/IP, users can control, configure and query the drive using an open, standards-based, industrial Ethernet connection at speeds up to 100 Mbits/sec.
STF03-EC EtherCAT
  • Specifically designed to operate on EtherCAT networks using the CANopen over EtherCAT (CoE) protocol.
  • Conforms to CiA DS402 specifications.
  • Supports Cyclic Synchronous Position(CSP), Profile Position, Profile Velocity and a range of Homing modes.
  • Able to run stored Q programs, which can be controlled over the EtherCAT network via Applied Motion-specific objects.
