Just a quick update of ION servo drive development: all hardware peripherals are now programmed and functioning properly and all hardware “typos” are corrected in the schematics & PCB layout. This is important milestone as now we can preparing the first production batch of hardware even when firmware is not fully complete. Firmware development will continue on prototype while we wait hardware from fabrication.
Meanwhile, I have been pondering how to make the higher power version of ION. Some options are:
- ION with 84 pin card edge connector (now 64 pin) and larger power stage. This can yield approx 10 A 90 VDC capability (limited by card edge connector).
- Add external power connector to ION. This eliminates card edge connector current & voltage but might would look weird and impractical. Also fitting large power stage on the board could be difficult.
- Get rid of card edge connector and replace all with wire terminals. This would easily give highest voltage & current rating but would not get benefit of ION motherboards, so wiring work would increase significantly. This option would look like updated VSD-E.
Which one sounds preferable to you? Leave a reply in comments :)
