Cause : Overvoltage (active in operating states of ≤ o4) - comes when the voltage across terminals 1U1, 1V1 or 1W1 and 3U1, 3W1 was higher than the response threshold for longer than the "restart time" set at P086 and the delay time according to P362 has expired.

Possible fault causes

  • Line overvoltage
  • Monitoring values set too sensitively or incorrectly (P352, P078)
  • Fault value: r047 Index 002 to 016:
  • 1 :  Overvoltage has occurred 002 Number of phase that has activated fault message
    0 ... Phase UV
    1 ... Phase VW
    2 ... Phase WU
    3 ... Phase field
    i003 Incorrect voltage value (normalized to 16384)
  • 4 : Undervoltage persists for longer than time set in parameter P086 (if this is >0)
