Quick start

Proceed as follows for standard commissioning of the EL9576 with an external resistor (e.g. ZB8110).

1. Install the EL9576 in the E-bus terminal segment on an EtherCAT coupler, e.g. EK1100 or EK1501.
   The terminal can also be used in exclusive conjunction with an EL9400 for operation without an EtherCAT connection.
2. For operation the EL9576 requires a supply voltage at connections 2 and 6 (U_IN) 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 V_DC.
• The resistor must be designed to handle the expected power and must be parameterized accordingly in the CoE data.
• 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.
3. Set up a correct EtherCAT configuration with the terminal.
   Since the device is present and is electrically reachable, the simplest way of accomplishing this is by scanning the devices.
4. Activate the EtherCAT master and start the terminal in OP state.
   In the input variables the EL9576 must deliver State=8 and WC=0.
5. Parameterize the resistor you are using in the CoE settings of the EL9576 according to the data sheet for the resistor.
• Reverse any previous parameter changes by means of a CoE reset: 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 in m°C/W in 0x8000:16.
  When the ZB8110 is used, the value is 1300 m°C/W.
• Enter the temperature time constant in seconds in 0x8000:17.
  When the ZB8110 is used, the value is 550 s.

What if...

the terminal is to be operated without the EtherCAT bus?

-> In this case it is still necessary to connect the Bus Terminal to an EtherCAT Bus Coupler or an EL9400 in order to connect the E-bus power supply. However, the bus coupler does not have to be connected to a fieldbus.
