3.5.2. Connection Diagrams
The following two connection diagrams (Figure 4, Figure 5) show the three different ways of
connecting the servo drive:
• 400 V and 800 V S models (the catalog number has an S option) that feature backup
functionality and require an auxiliary 24 V backup supply. The drive will not be operative
without the external 24 VDC supply.
• 400 V model without backup functionality. The drive’s internal DC/DC converter is fed from
the VP+ and VN- of the internal drive’s bus line.
