The AKT2G-SM-L50 EtherCATClosed Ethernet ofr Control Automation Technology. EtherCAT® is an open, high-performance Ethernet-based fieldbus system. The development goal of EtherCAT is to apply Ethernet to automation applications which require short data update times (also called cycle times) with low communication jitter (for synchronization purposes) and low hardware costs. Terminal is intended for stepper motors with medium performance range. The PWM output stages cover a wide range of voltages and currents. Together with two inputs for limit switchesClosed Switch limiting the traverse path of the machine. Implemented as n.c. (break) contact. A sensor, typically Hall-effect, optical, eddy current, or mechanical, which is used to sense the end of travel of a linear motion assembly. In addition to preventing over travel, it is frequently used to establish a precision reference., they are located in the EtherCAT Terminal.

The SM-L50 can be adjusted to the motor and the application by changing just a few parameters. 64-fold micro-stepping ensures particularly quiet and precise motor operation. Together with a stepper motor and an encoderClosed Generates an output signal directly proportional to the movement of the motor shaft. This signal is fed into the control circuitry to control the shaft position and speed. The most common types are: Incremental/Serial encoders, Hall effect sensors, Resolvers, Tachometer Generators See: Optical encoders., the SM-L50 represents an inexpensive small servo axis.

The LEDs indicate status, warning and error messages as well as possibly active limitations.

Technical Data

Technical Data AKT2G-SM-L50
Number of outputs 1 stepper motor, 2 phases
Number of digital inputs 2 limit positionClosed Position means a point in space which is described by different coordinates. Depending on the used system and transformation it can consist of a maximum of six dimensions (coordinates).This means three Cartesian coordinates in space and coordinates for the orientation. In ACS there can be even more than six coordinates. If the same position is described in different coordinate systems the values of the coordinates are different., 4 for an encoder system

ResolutionClosed The resolution is the smallest possible movement that can be achieved by a system. It can be defined at the electronics, encoder and mechanics level. The distance a stage can be commanded to move in a single step.
