- Pos 0: Change in the voltage according to
the U/F ratio, knee-point position at 48 Hz.
- Pos 1: Change in the voltage according to
the 2U/F, knee-point position at 48 Hz.
- Pos 2: Change in the voltage according to
the self auto-adaptating LAM combined with
2U/F, knee-point position at 48 Hz.
- Pos 3: Change in the voltage according to
the U/F ratio, knee-point position at 58 Hz
- Pos 4: Change in the voltage according to
the 2U/F, knee-point position at 58 Hz.
- Pos 5: Change in the voltage according to
the self auto-adaptating LAM combined with
2U/F, knee-point position at 58 Hz.
- Pos 6: Change in the voltage according to
the U/F ratio, knee-point position at 65 Hz
(Tractelec application and variable speed
above 1800 rpm).
- Pos 7: Special (not used).
- Pos 8: Change in the voltage according to
the U/F ratio, knee-point position at 48 Hz or
58 Hz according to selection of the frequency
by an external contact.
- Pos 9: Change in the voltage according to
LAM 1, knee-point position at 48 Hz or 58 Hz
according to selection of the frequency by
an external contact
WARNING
For Pavers and hydraulic applications,
select positions 0 (50 Hz) or 3 (60 Hz).
