F07860 (A) External fault 1
Message class: External measured value / signal state outside the permissible range (16)
Reaction: OFF2 (IASC/DCBRK, NONE, OFF1, OFF3, STOP2)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The condition for "External fault 1" is satisfied.
Note:
The "External fault 1" is initiated by a 1/0 edge via binector input p2106.
See also: p2106 (External fault 1)
Remedy: - eliminate the causes of this fault.
- acknowledge fault.
F07861 (A) External fault 2
Message class: External measured value / signal state outside the permissible range (16)
Reaction: OFF2 (IASC/DCBRK, NONE, OFF1, OFF3, STOP2)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The condition for "External fault 2" is satisfied.
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.
F07862 (A) External fault 3
Message class: External measured value / signal state outside the permissible range (16)
Reaction: OFF2 (IASC/DCBRK, NONE, OFF1, OFF3, STOP2)
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 (External fault 3), p3110 (External fault 3 switch-on delay), p3111 (External fault 3 enable), p3112
(External fault 3 enable negated)
Remedy: - eliminate the causes of this fault.
- acknowledge fault.
A07891 Drive: Load monitoring pump/fan blocked
Message class: Motor overload (8)
Reaction: NONE
Acknowledge: NONE
Cause: The load monitoring is configured for a pump or fan (p2193 = 4, 5).
The monitoring function detects when the pump/fan is blocked.
It is possible that the blocking torque threshold (p2168) is set too low (e.g. heavy duty starting).
See also: p2181 (Load monitoring response), p2193 (Load monitoring configuration)
Remedy: - check whether the pump/fan is blocked, and if blocked, then resolve the problem.
- check that the fan can freely move, and if necessary, resolve the problem.
- adapt the parameterization corresponding to the load (p2165, p2168)..
