4.2 List of faults and alarms
SINAMICS G130/G150
1490 List Manual (LH2), 04/2014, A5E03263479A
Note:
The "External fault 2" is initiated by a 1/0 edge via binector input p2107.
See also: p2107 (External fault 2)
Remedy: - eliminate the causes of this fault.
- acknowledge fault.
Reaction upon A: NONE
Acknowl. upon A: NONE
F07862 (A) External fault 3
Message value: -
Message class: External measured value / signal state outside the permissible range (16)
Drive object: All objects
Reaction: Vector: OFF2 (IASC/DCBRK, NONE, OFF1, OFF3, STOP2)
Infeed: OFF2 (NONE, OFF1)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The condition for "External fault 3" is satisfied.
Note:
The "External fault 3" is initiated by a 1/0 edge via the following parameters.
- AND logic operation, binector input p2108, p3111, p3112.
- switch-on delay p3110.
See also: p2108, p3110, p3111, p3112
Remedy: - eliminate the causes of this fault.
- acknowledge fault.
Reaction upon A: NONE
Acknowl. upon A: NONE
F07890 Internal voltage protection / internal armature short-circuit with STO active
Message value: -
Message class: Application / technological function faulted (17)
Drive object: VECTOR_G
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: The internal armature short-circuit (p1231 = 4) is not possible as Safe Torque Off (STO) is enabled. The pulses
cannot be enabled.
Remedy: Switch out the internal armature short-circuit (p1231=0) or de-activate Safe Torque Off (p9501 = p9561 = 0).
Note:
STO: Safe Torque Off / SH: Safe standstill
F07898 Drive: flying restart unsuccessful due to excessively low flux
Message value: -
Message class: Motor overload (8)
Drive object: VECTOR_G
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: While identifying the rotor position of a separately-excited synchronous motor based on voltage measurement, after
the excitation time had elapsed, the flux was too low.
Remedy: Increase the excitation time (p0346).
