    Description

    SD4840EK Integrated Stepper Motor Controller + Drive Networked I/O

    AMCI's SD4840EK Integrated Stepper Indexer / Driver for the EtherCAT network reduces stepper control system costs by eliminating the need for a separate stepper controller in your PLC - we've built the indexer into the driver! Plus, programming and configuration over the network is easy because it uses the PLC's native software (eg. Beckhoff TwinCAT). No extra software is required, and you don't need to learn another programming language. AMCI's SD4840EK Integrated Drive interfaces with your EtherCAT compatible PLC (Beckhoff, B&R Automation, and others), saving you time and money!

    If you're seeking flexibility, AMCI's SD4840EK Integrated Stepper Drive scores high marks. We've made it easy to add stepper axes wherever you need them on your EtherCAT network, just plug in another SD4840EK Networked Series drive and configure your network - done.

    Design Features

    Besides connectivity with EtherCAT, AMCI's SD4840EK Integrated Drive boasts several features over conventional stepper drivers. Our vari-step velocity control provides unsurpassed smoothness and performance independent of the user’s configured resolution. Smoothness is guaranteed even at the lowest resolutions. Plus, a narrow and compact design saves space, and versatile mounting options allow for panel or side installation.

    Safety & Reliability

    Standard AMCI safeguards also remain; including an interlock connection to prevent injury if the motor connector is removed while the driver is powered. Additional protections include short circuit protection - phase to phase and phase to ground- and over temperature circuitry.

    Compatibility

    Besides AMCI’s trademark reliability, the SD4840EK Stepper Indexer / Driver for EtherCAT was engineered to power AMCI's complete line of high torque stepper motors, ranging in size from NEMA 17 to NEMA 34.

    This combination of stepper motor driver and indexer provides the best performance for your application. Performance, price, and product all combine to offer you the best value.
