Phase UW Short

What does 43 mean?

Excessive current has been detected between output terminals U and W. This indicates a short circuit condition between these two motor phases or their connecting wiring, leading to very high currents and potential drive damage.

• Short circuit detected between Phase U and Phase W.
• Damaged insulation between Phase U and Phase W motor windings.
• Faulty motor power cable with U and W shorted.
• Internal short circuit in the drive's output stage.
