Lenze i950 - Safe Muting (MUT)

Safe mung (MUT)
(From standard device rm
ware V1.3, safety rmware V1.1 with parameter set version V1.1)
The “safe mung
” safety funcon may only be used during commissioning or
maintenance work.
It serves to move the motor even if the inverter is in a safety state.
The safe mung funcon deacvates selected safe inputs and all funcons of the safety bus.
The safe mung funcon can only be acvated via the LSPE (Lenze Safety Parameter Editor).
For this purpose, a special mung password must be entered.
Within a network, the safe mung funcon c
an always only be acvated for one inverter.
The safe mung funcon is maximally acve for 30 minutes. It can be interrupted or stopped
anyme.
Please note the following:
If the sa
fe mung funcon is stopped or interrupted by an error, the inverter
automacally changes to the monitored state.
All safety funcons that have been deacvated before become acve again.
DANGER!
Acvang the sa
fe mung funcon deacvates safety funcons!
This may result in severe injuries or death!
▶
Only authorized personnel is permied to acvate the safe mung funcon.
▶
One input must be parameterized as emergency stop. This input must not be deacvated by
safe mung.
