Touch probe: Detected touch probe position sporadically deviates significantly (corrected from V1.7.6)

Corrected from:
- i700 V01.07.06.10729

Response of the new version:
The i700 servo inverter always correctly detects the touch probe position. 

 

 
What happens?
Sporadically, the touch probe position detected by the i700 servo inverter deviates significantly from the actual TP position.
The position deviation depends on the current speed during TP detection. The deviation is as follows:
Distance that can be covered in 32 ms at the current speed.
I.e., in the case of a position deviation, the offset is clearly visible. 
 
When does this behaviour occur?
The described position deviation only occurs sporadically, approx. every tenth time.
 
Which products are affected?
- i700 servo inverter - only version V01.07.05.10577
 
Short-term measures:
Use the new i700 firmware version V01.07.0610729 or higher which was created immediately after the problem became known.
The new i700 firmware version is automatically installed via the EASY Package Manager. 
 
Evaluation/recommendations:
The new firmware version is available for applications in which the touch probe function of the i700 is used, e.g. homing or TP positioning.
