Hiperface DSL (OCT): When switching off, an encoder error is erroneously detected and the reference status is deleted (corrected from V01.05.02)

Corrected from:
Servo Inverter i950 FW:  from V01.05.02.1788

Response of the new version:
When switching off the 24V supply, an encoder error is no longer erroneously detected and the reference status is no longer lost.

 
What happens?
As a result of the erroneous occurrence of an encoder error, the reference status reference-known is lost. After the next power-on, the reference position must be determined again.

When does the behaviour occur?
When using a Hiperface DSL feedback system in One Cable Technology (OCT) and
when the 24V power supply is switched off.
The slope of the ramp with which the 24V voltage drops has an influence on the probability of the encoder error occurring.

Which products are affected?
Servo inverter i950 FW

Short-term measures / Evaluation / Recommendations:
A more theoretical possibility to prevent the occurrence of an encoder error would be the reduction of the ramp slope when the 24V supply decays.
