Abstract:
A motor drive device has an abnormality detection function for a power supply unit between its own device and a power supply, and includes: a forward converter that is inputted AC power from the power supply via the power supply input part, and converts the AC power into DC power; a reverse converter that converts the DC power from the forward converter into AC power; a DC link capacitor provided to a DC link between the forward converter and the reverse converter; a voltage detection part that detects voltage of the DC link capacitor; and an abnormality detection part that obtains a voltage change amount for a predetermined time of the DC link capacitor based on voltage values detected by the voltage detection part, and performs abnormality detection on the power supply input part based on the voltage change amount thus obtained.

Claim (Index 4):
The motor drive device according to  claim 3 , wherein the storage part externally allows for rewriting of the threshold.
