Fanus Control Model: Series 15 control (including Series 15-MA, 15-TA, 15-MF, and 15-TF).
Description
When the G05 command is written incorrectly in the program or the controller detects a technical error in the use of the G05 command. One reason for this alarm is that the G05 command is written during a canned cycle.
How to Fix Alarm
Check the G05 code and correct the syntax to make sure there are no extra dots or characters. Often, simply using G05.1 Q1 (AI Nano Control) instead of G05 will also solve the problem, provided your machine supports it.
Ensure you use G05 P10000 (start) and G05 P0 (end) correctly for your specific control model.
