State of the 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. State MachineClosed The complete assembly of all connected parts or devices, of which at least one is movable.: INIT = Initialization of the terminal or BOOTSTRAP = FunctionClosed A function calculates a result according to the current value of its inputs. A function has no internal data and is not linked to declared instances. for firmware updates of the terminal

State of the EtherCAT State Machine: PREOP = Setting for mailbox communication and variant standard settings

single flash

State of the EtherCAT State Machine: SAFEOP = Channel checking of the Sync Manager and the Distributed ClocksClosed Clock signal.. Outputs stay in safe operation mode.

on

State of the EtherCAT State Machine: OP = Normal operation mode, mailbox- and process data communication possible

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.

Meaning

DriverClosed In computing and electronics, a driver is a software component allowing higher-level computer programs to interact with a computer hardware device. A driver typically communicates with the device through the computer bus or communications subsystem to which the hardware is connected.

Encoder supply +24V

Encoder supply (from positiveClosed 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. power contact)
