allowed thermal overload.
7.2.92 ALARM 164, ATEX ETR Cur.Lim.Alarm
Cause
Running above the characteristic curve for more than 60 s within a period of 600 s activates the alarm, and the drive trips.

Cause
The drive has run for more than 60 s (in a period of 600 s) below the allowed minimum frequency (parameter 1-98 ATEX ETR Interpol.
Points. Freq.).
