Control of the "Power Failure Monitoring (UVO)" function block
using the monitored signal (any socket
e.g. device inputs, control bits from PROFIBUS DP , etc.)
Specification of the type of power failure monitoring:
• Deactivated
• Device supply is not interrupted.
The control voltage from SIMOCODE pro remains constant.
The interruption of the mains voltage must be measured, for
example, by a separate voltage relay.
Start time after power failure.
If the mains voltage returns within the power failure time, all the
drives that were connected before the power failure are
automatically reconnected.
If the mains voltage does not return within this time period, the
drives remain disconnected and the "Trip - Power failure (UVO)" fault
message is generated.
Once the mains voltage has returned, the fault message can be
acknowledged using "Reset".
Range:
0 to 25.5 s in 0.1 s increments
26 to 255 s in 1 s increments
256 to 2550 s in 10 s increments
The restart time delay can be set so that not all motors restart
simultaneously (the mains voltage would otherwise fail again).
Range: 0 to 255 seconds.
