Servo Drive Repair

The assessment covers the power module, power supply, control electronics and an appropriate operational test. The terms drive and inverter are used according to device category; not every inverter is considered a servo drive.

Parameters and backup: whether a backup can be taken depends on the condition of the device and on access; no guarantee is given that data will not be lost. If possible, back up your existing parameters before shipping.

• Alarm codeA recurring error on the display; the code and the conditions under which it occurs matter.
• No power-upPower is present, but the drive does not start up.
• Frequent trippingCuts out at a certain load or temperature.
• Motor does not startA command is given, but there is no movement.

A symptom is not a diagnosis; the cause becomes clear during laboratory diagnosis.

The wording “tested under load” is used according to device compatibility and the test actually performed; it is not assumed that every drive is tested in the same way. Alarm examples have no universal meaning without the brand and model.
