SINAMICS G130/G150List Manual (LH2), 04/2014, A5E03263479A 14974 Faults and alarms4.2 List of faults and alarmsF07913 Excitation current outside the tolerance rangeMessage value: -Message class: Application / technological function faulted (17)Drive object: VECTOR_GReaction: OFF2Acknowledge: IMMEDIATELYCause: The difference between the excitation current actual value and setpoint has exceeded the tolerance:abs(r1641 - r1626) > p3201 + p3202The cause of this fault is again reset for abs(r1641 - r1626) < p3201.Remedy: - check the parameterization (p1640, p3201, p3202).- check the interfaces to the excitation equipment (r1626, p1640).- check the excitation equipment.F07914 Flux out of toleranceMessage value: -Message class: Application / technological function faulted (17)Drive object: VECTOR_GReaction: OFF2Acknowledge: IMMEDIATELYCause: The difference between the flux actual value and setpoint has exceeded the tolerance:abs(r0084 - r1598) > p3204 + p3205The cause of this fault is again reset for abs(r0084 - r1598) < p3204.The fault is only issued after the delay time in p3206 has expired.Remedy: - check the parameterization (p3204, p3205).- check the interfaces to the excitation equipment (r1626, p1640).- check the excitation equipment.- check the flux control (p1590, p1592, p1597).- check the control for oscillation and take the appropriate counter measures (e.g. optimize the speed control loop,parameterize a bandstop filter).A07918 (N) Three-phase setpoint generator operation selected/activeMessage value: -Message class: Application / technological function faulted (17)Drive object: B_INF, VECTOR_GReaction: NONEAcknowledge: NONECause: Only for separately excited synchronous motors (p0300 = 5):The actual open-loop/closed-loop control mode is I/f control (open-loop) with a fixed current (p1300 = 18).The speed is entered via the setpoint channel and the current setpoint is given by the minimum current (p1620).It must be ensured that in this mode, the control dynamic performance is very limited. This is the reason that longerramp-up times should be set for the setpoint speed than for normal operation.See also: p1620 (Stator current minimum)Remedy: Select another open-loop/closed-loop control modeSee also: p1300 (Open-loop/closed-loop control operating mode)Reaction upon N: NONEAcknowl. upon N: NONEA07920 Drive: Torque/speed too lowMessage value: -Message class: Application / technological function faulted (17)Drive object: VECTOR_GReaction: NONEAcknowledge: NONECause: The torque deviates from the torque/speed envelope characteristic (too low).See also: p2181 (Load monitoring response)
