Question about 7I77

Hello,
I have install a 7I77 for driving my woodcnccenter with servomotors. The 7I77 has 4 screwplugs for field power. Its necessary to connect all 4 screwplugs to 24Volt or is one enough?

Thanks

Hans

One 24V connection is sufficient for most uses (say up to 1A total output load)

if you have the full load on all outputs (~3A) I would use all four
