Possible Solutions and Notes

Error Messages:

• Alarm #123: Spindle Drive Error
• Alarm #160: Undervoltage

Problem:
The machine reports an undervoltage, a common issue with many devices. The customer sees on the machine control display that the target voltage is not being reached – it should be around 320 volts DC.

Symptom Progression:

• Initially, the error occurs sporadically. The device often only works again, after warming up or after several power cycles. This is a typical approach used by many operators.
• Over time, the problem worsens: it takes longer for the device to work after being turned on, and more power cycles are needed.

Risk:
Repeated power cycling and improper handling can cause the buffer electrolytic capacitors inside the device to explode. In such cases, the device may fail completely and is often beyond repair.

Recommendation:
As soon as the error occurs, the device should be taken in for repair immediately to avoid more severe damage.
