The EL5042 EtherCAT Terminals is a BiSS-C master and enables the direct connection of an absolute encoder with BiSS-C or SSI interface. Both singleturn and multiturn encoders are supported. The EL5042 also provides an encoder supply of 5 V or optionally 9 V.

The extensive parameterization allows optimum adaptation to different encoder types.

Special features:

• unidirectional BiSS-C communication
• Parameterization per channel possible
• Baud rate up to max. 10 MHz
• separate evaluation of the error and warning bit in the process data
• Position value output with up to 64 bits (depending on the encoder resolution)
• also usable as SSI master

Via the distributed clocks function, the position value is read out exactly synchronously with other processes. If the distributed clocks function is deactivated, the EL5042 clocks synchronize with the EtherCAT cycle

The use of encoder profiles enables simple and fast linking of process data for Motion Control applications.
