Since our upcoming servo drive VSD-E will be 12-80 VDC drive and there is a clear market for high voltage drive that can be operated directly from mains voltages (115/230VAC), I'm creating this poll to gather user opinions about preferred servo drive constructions.
I have 3 different drive types in mind that would allow such operation:
- VSD-E without on-board power stage. It would just have connector for external power stage.
- Small sized control card with pin headers. This could be plugged on "mother board" containing the power stage.
- Monolithic design. Everything on one board and possibly a metal enclosure for it.
Options 1-2 allows controlling virtually any power and option 3 would be the easiest to use.
Attached picture shows VSD-E drive if one isn't already familiar with it. Option 1 would look much like, but 1/2 of this size.
