What does SVALM mean?
The SVALM (Red) LED lights when the servo amplifier detects an internal alarm. This fault is indicated if the LED lights up when there is no apparent alarm condition in the machine, or if it does not light up when there *is* an alarm condition. This suggests a malfunction in the servo amplifier's internal diagnostic system or its alarm logic.
