SRVO-225: Unsupported servo card
Wrong-generation hardware: an R-30iB servo card is installed in an R-30iB Plus controller, which doesn't support it.
What it means
Wrong-generation hardware: an R-30iB servo card is installed in an R-30iB Plus controller, which doesn't support it. Same one-minute CPU-stop behavior as the fan alarms - the controller halts to protect itself. The message number decodes which board: 1 = servo card, 2 = aux axis board 1, 3 = aux axis board 2.
Common causes
Ranked by what technicians most often find, most likely first.
- R-30iB-generation servo card or aux axis board fitted in an R-30iB Plus controller - typically after a parts swap using older stock.
How to fix it
- Identify the board from the message number and replace it with the R-30iB Plus-compatible part, with the controller de-energized and locked out.
- Note the urgency: the CPU stops and the pendant freezes one minute after the alarm, so this is not a run-through-the-shift condition.
