SRVO-135: FSAL alarm (aux amplifier fan stopped)
The control-circuit cooling fan on an auxiliary servo amplifier (αiSV) has stopped for the named axis.
What it means
The control-circuit cooling fan on an auxiliary servo amplifier (αiSV) has stopped for the named axis.
Common causes
Ranked by what technicians most often find, most likely first.
- Failed internal fan in the αiSV.
- Failed αiSV amplifier.
- Same reset-timing quirk as SRVO-134: RESET input within 2 seconds of an E-stop-type signal can trigger this on aux-axis systems.
How to fix it
- Replace the aux amplifier's internal fan motor.
- Replace the αiSV if the fan isn't the issue.
- Enforce the 2-second gap between E-stop-type signals and RESET on aux-axis systems. Power-cycle to clear.
