Corrected from:
84TL V21.01
Response of the new version:
An Sd6 or Sd12 error is not generated erroneously.
What happens?
The combination 8400 Topline with a Profinet module results in an extended initialization time.
During this time no measured temperature value is available, so that the temperature monitoring checks a wrong value which is outside the permissible tolerance. The reaction is the error message Sd6, if a resolver is used or Sd12 if an encoder is used.
When does the behaviour occur?
When using a motor with a PT1000 temperature sensor and a Profinet module at the same time, an error message Sd6 / Sd12 has occurred in many cases up to now.
Which products are affected?
8400 TopLine with a firmware < 21.01.00.00
Short-term measures:
By switching the temperature measurement to "special characteristic", false triggering can be prevented.
C01190 / x : Special characteristic
C01191 / 1 : 0 C°
C01191 / 2 : 200 C°
C01192 / 1 : 1000 Ohm
C01192 / 2 : 2100 Ohm
Disadvantage: at low temperatures the displayed value shows a high deviation. However, the cut-off point for overtemperature works correctly.
Evaluation/Recommendations:
With the use of the "special characteristic curve" a simple work around is available.
