Notice

Pinout 2:

Damage to devices possible!

  • The pins named with “NC” must not be connected.
  • Before installation, read the chapter Installation of EJ modules!
  • Before commissioning, read the detailed description of the process data, operation modes and parameterization in the EL5042 documentation!

The following points should be considered during design phase and installation:

Notes for routing and installation

  • The encoder supply is connected externally, e. g. via the power supply plug-in module EJ9505.
  • The BiSS and SSI information (Clock and Data) are transmitted as differential signals. To ensure a good EMC immunity, also for long distances, shielded cables with twisted pair conductors should be used.
  • The cable shield should be connected to earth at both channel ends and the two end devices should be always at the same reference potential.
  • When using externally shielded cables, particular care should be paid, not to damage or to interrupt the shield itself.
  • Shield should be connected near by the connector.
  • Refer also to the corresponding notes of the sensor manufacturer!
  • Refer to the guide lines in the design guide for the EtherCAT plug-in modules to ensure a proper routing of the differential signals!
  • The value of each termination resistor should be equal to the cable characteristic impedance, typically 120 Ω for EIA-485 or RS-482 standard.
  • Routing of the differential signals should be impedance controlled with typically 120 Ω for EIA-485 or RS-482 standard. Traces wide should be > 0.2 mm, the maximum ampacity need to be taken into account.
  • To improve the EMC immunity it may be helpful to connect the two signal channels on two different connectors
