Parker Compumotor Gemini drive down — and no replacement to be found?

The Gemini servo and stepper line (GV6, GV6K, GT6, GT6K) is officially obsolete, but you don't have to scrap a perfectly good machine over one failed drive. We just published a full repair guide covering:

🔧 The most common Gemini failure points (power stage, gate drivers, DC bus caps, encoder feedback, RS-232/485 comms)
🔧 How to tell GV6 servo vs GT6 stepper — and decode the part number
🔧 When repair beats replacement on a legacy drive

Component-level repair. Free diagnostic. 2-year warranty. Nationwide mail-in from our Texas facility.

Line went down mid-shift because a Parker 890 tripped and the spare cabinet was empty — sound familiar? This buying guide covers Variable Frequency & Variable Speed Drives (VFD) in the Parker 890 series specifically: in-stock vs. refurbished vs. depot repair options, what to verify before you buy used, and how to avoid getting burned on a pulled unit with unknown run hours. Worth bookmarking before the next unplanned outage hits.

When you've pulled a faulted 890 VFD, what's your go/no-go checklist before deciding repair vs. replace — any specific failure signatures on the 890 that push you straight to replacement rather than sending it out?
