8 Monitoring functions
The i700 servo inverter is provided with various monitoring functions, which are described in the
following subchapters.
Objects described in this chapter
8.1 24-V supply voltage monitoring
The 24 V supply voltage is monitored by means of two specified voltage thresholds.
• The following table describes these thresholds and shows the device response resulting from
the level of the supply voltage:
