Panel Mount Stepper Drives

STF10 - DC Advanced Microstep Drive w/ Multi Fieldbus options

The STF10 stepper drive is a DC-powered microstepping drive for controlling two-phase, bipolar step motors. It offers advanced current control and an anti-resonance algorithm that electronically damps motor and system resonances to improve motor smoothness and usable torque over a wide speed range. The drive employs electronic torque ripple smoothing and microstep emulation to greatly reduce motor noise and vibration. The drive must be powered from 24 to 70 VDC and can output up to 10.0 A/phase (peak-of-sine) to the step motor. Over-voltage, over-temperature and over-current protection features prevent damage while running in adverse conditions.

Drive part number	Communications	Description
STF10-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.
STF10-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.
STF10-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.
STF10-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.
STF10-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.
