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.
• The voltage monitoring is active in the device statuses " Ready to switch on ", " Switched on ",
" Operation enabled " and " Quick stop is active ".
• The warning thresholds for the monitoring are adjustable and preset for a rated mains voltage
of 400 V in the Lenze setting.
• The error thresholds for the monitoring result from the set rated mains voltage:

Subindex 2: Undervoltage (LU): Warning threshold
Warning threshold for monitoring with regard to undervoltage
• If the DC-bus voltage of the i700 servo inverter falls below the threshold value set here, the device reports a
warning. Reset is effected with a hysteresis of 10 V.
