Tripping of SSI encoder error message: "LS_MultiEncoder: Max. position jump"

Corrected from: 

Response of the new version:

From the new version onwards, an SSI-encoder overflow will be included in the "LS_MultiEncoder: Max. position jump" monitoring function and no error will be tripped.

What happens?

When the max. position jump monitoring function is active, the "LS_MultiEncoder: bFail" output bit is not set correctly.

When does this behaviour occur?

The behaviour occurs when using a rotary SSI encoder and overtravelling the value range (overflow of the position read by the SSI encoder). Activation of code C1112:4.

Which products are affected?

• Inverter Drives 8400 protec HighLine lower than V08.01.00 0.37 kW - 5.5 kW
• Inverter Drives 8400 protec HighLine lower than V16.01.00 7.5 kW
