The AKT2G-BRC-000 EtherCAT 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 contains high-performance capacitors for stabilizing supply voltages.
The AKT2G-BRC-000 can be used, for example, in conjunction with the AKT2G-SM-L50-000 or AKT2G-SM-L15-000 stepper motor An actuator focused to a movement, converting electrical energy in a force or torque. terminal. Low internal resistance and high pulsed When the step gets activated, the action is activated for a single execution, and possibly once again when the step is deactivated. current capability enable Enable signal for the drive, Hardware-Enable with 24V signal to X8, Software-Enable command by setup Software, fieldbus or permanently set. Both are required for enabling the drive. good buffering in parallel with a power supply unit.
Return currents are stored, particularly in the context of drive In electrical engineering, a drive is an electronic device to provide power to a motor or servo. Control device for regulating the speed, torque and position of a motor. A unit controlling a motor using the current and timing in its coils. applications, thereby preventing overvoltages. If the recovery energy exceeds the capacity of the capacitors, energy can be dissipated via an external ballast resistor. The switching threshold for this can be parameterized via the KAS-IDE Kollmorgen Automation Suite - Integrated Development Environment.

Installation position 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. | Any, see Mounting and Wiring of I/O Terminals |

LEDs and Pin Assignment
-
-
Correct supply voltage is necessary for operation!
In addition to the supply voltage via the contacts on the front panel, the voltage from the E-bus must also be present in order for the terminal to work properly, since the integrated logic of the Bus Terminal is supplied with this voltage. The Bus Terminal does not work if the supply is incorrect.
-
-
Match the resistor power to the expected power!
When selecting the external resistor, make sure that the rated power of the resistor is matched to the expected power, since otherwise the resistor and adjacent components can be damaged. In addition, the temperature model is to be adapted to this resistor.

Brake Chopper Quick Start
Proceed as follows for standard commissioning of the AKT2G-BRC-000 with an external resistor.
- Install the AKT2G-BRC-000 in the E-bus terminal segment on an EtherCAT coupler,.
- For operation the AKT2G-BRC-000 requires a supply voltage at connections 2 and 6 (UIN) of the terminal as well as a power supply via the E-Bus. The following must be observed:
- The supply voltage must be at least 18 VDC.
- The resistor must be designed to handle the expected power and must be parameterized accordingly via CoE Init-Commands.
- The voltage supply must be designed for the switching on of the corresponding resistor.
- Supply quality: the most stable and noise-free supply possible must be ensured.
- Parameterize the resistor you are using with CoE Init-Commands according to the data sheet for the resistor.
- Reverse any previous parameter changes by means of a CoE reset New start of the microprocessor.: enter 0x64616F6C in object 0x1011:01.
- Enter the ambient temperature of the resistor in °C in 0x8000:15.
- Enter the thermal resistance of the electrical resistor to the environment Environment objects are global objects that exist before the execution of the script. Typically, they are global objects of Astrolab that can be accessed from the script. in m°C/W in 0x8000:16.
