Operating at 50 Hz: (U/F gradient)
0: threshold at 48 Hz without LAM for impacts between 30 and 40% of the rated load.
1: threshold at 48 Hz with LAM 13% for impacts between 40 and 70% of the rated load.
2: threshold at 48 Hz with LAM 25% for impacts > 70% of the rated load. Operating at 60 Hz: (U/F gradient)
3: threshold at 58 Hz without LAM for impacts between 30 and 40% of the rated load.
4: threshold at 58Hz with LAM 13% for impacts 40 and 70% of the rated load.
5: threshold at 58Hz with LAM 25% for impacts > 70% of the rated load. Specific operating
6: threshold at 57Hz without LAM for speed variations at a steady state > 2 Hz
7: threshold at 65Hz without LAM for variable speed and tractelec / gearlec (U/F gradient).
8: special: the factory setting 48Hz 2U/F gradient ; a special programme is possible on request. This programme must be specified before ordering, during the project study.
9: threshold at 47.5 Hz without LAM for speed variations at a steady state > 2 Hz. For hydraulic applications, it is advisable to select: - position 0 for 50 Hz - position 3 for 60 Hz
