Low Power Supply Input Voltage

What does SP0010 mean?

The input voltage to the low-power supply section of the spindle amplifier is below the acceptable threshold. This can cause unstable operation or prevent the amplifier from powering on.

• Low input AC voltage to the spindle amplifier.
• Failure of the amplifier's internal low-voltage power supply circuitry.
• Loose connections on the low-voltage power input terminals.
• Faulty control transformer supplying the amplifier's auxiliary power.
• Overload on the low-voltage control circuits.

Click steps to track your progress.

1. 1

   Measure the input AC voltage at the amplifier's L1, L2, L3 terminals.

2. 2

   Verify the output voltage of the amplifier's internal low-voltage rails (e.g., 24VDC).

3. 3

   Inspect low-voltage power connector for proper seating and corrosion.

4. 4

   Check the primary and secondary voltages of the control transformer.

5. 5

   Monitor the low-voltage supply during amplifier operation for dips.
