Facts and Changes
16 UNITS OF VW3A58310. WHEN REPETITIVE UDP FRAME OF 1525 BYTES POLLING RATE 5 MS
Causes and Fixes
Be careful, with UDP there is no guarantee on the datagram validity , if the datagram in not complete the inverter will trip in ILF, and it's necessary to have some time to analyse 1525 bytes and a clogging is possible at the input card, try to increase the polling and if it's possible use the TCP mode.
USER MANUEL P100 English version : The Ethernet card is compliant with ETHERNET 2 frames format (IEEE 802.3 is not supported).
If you server can support only this mode, the only solution is to replace it.
