[etherlab-users] Beckhoff EL5032

 Anyone has used beckhoff EL5032 with ethercat master(version 1.5.1)?
The EL5032 EnDat 2.2 EtherCAT Terminal is used for direct connection of two encoders with EnDat 2.2 interface. The EL5032 enables reading of position values, diagnosis encoder data, internal and external temperature values and the electronic identification plate. With the electronic identification plate all measuring device-specific information is directly available. In addition, user-defined data can be stored in the encoder. This enables cost-effective and quicker commissioning. The position value is output with up to 48 bits, depending on the resolution of the connected measuring device. In addition to the position value, further information such as status information, addresses and data can be transferred. A list of additional information supported by the encoder is stored in the parameters. The EL5032 features distributed clocks, which means that the position value can be read in exact synchrony with the system. If the distributed clock function is deactivated, the EL5032 cycles synchronous with the EtherCAT cycle.
I have used this module to sample encoder position, but found that the feedback position was jitter sometimes. And I have also enabled its DC function(with Sync0 cycle time 1ms).
