4.5 Monitoring of the DC-bus voltage
For the device as a whole, the DC-bus voltage is monitored with regard to undervoltage and
overvoltage.
Monitoring of the warning thresholds
The warning thresholds for the monitoring are adjustable and preset for a rated mains voltage of
400 V in the Lenze setting.
Voltage monitoring of the warning thresholds is active in the "Ready to switch on
", "Switched on",
"Operation enabled
", and "Quick stop active" device states.
Monitoring of the error thresholds
• Up to and including version 01.06, the error monitoring function is active in the "Ready to switch
on", "Switched on", "Operation enabled", and "Quick stop active" device states.
• From version 01.07 onwards, voltage monitoring of the error thresholds is active in the
"Operation enabled
" and "Quick stop active" device states.
The error thresholds for the monitoring process are determined on the basis of the rated mains
voltage set:
*)
Only permissible for setting up a system! For all other operating states, this rated voltage is impermissible.
