If the UPS operaon is acve,
•
the device overload monitoring (i*t) is adapted accordingly.
•
the DC limit values are reduced.
•
the phase failure detecon is switched o.
•
the warning "UPS operaon acve" (error code 12672 | 0x3180) is output.
•
trigger "UPS operaon acve [118]" is set to TRUE. The trigger can be assigned to a digital
output.
•
bit 15 ("UPS operaon acve") in the inverter status word 2 0x2833 is set to "1".
Notes:
•
An addional limitaon of speed, current, etc. can be realised via the applicaon with the

Assignment of a trigger to the "Acvate UPS operaon" funcon.
Trigger = TRUE: Acvate UPS operaon.
Trigger = FALSE: no acon / deacvate funcon again.
0 Not connected No trigger assigned (trigger is constantly FALSE).
