Voltage measured values not plausible p. 697

Common causes

  • The voltage measurement does not supply any plausible values and is not used. p. 697
  • Alarm value (r2124, interpret bitwise binary): Bit 1: Phase U Bit 2: Phase V Bit 3: Phase W p. 697
  • The following parameterization must be made in order to deactivate the alarm: p. 697

What to do

  1. - Deactivate voltage measurement (p0247.0 = 0). - Deactivate flying restart with voltage measurement (p0247.5 = 0) and deactivate fast flying restart (p1780.11 = 0). p. 697
