4 Faults and alarms
4.2 List of faults and alarms
F06700 (A) Infeed: Switch line contactor for load condition
Message value: -
Message class: Infeed faulted (13)
Drive object: B_INF
Reaction: NONE (OFF2)
Acknowledge: IMMEDIATELY
Cause: For an ON command, the infeed line contactor should be switched under load.
Remedy: - do not load the DC link if the infeed has not issued an operating signal (r0863.0 = 1).
- after the infeed has been powered down, all power units connected to the DC link should be powered down. To
realize this, the operating signal of the infeed (r0863.0) must be suitably interconnected.
Reaction upon A: NONE
Acknowl. upon A: NONE
A06810 (F) Infeed: DC link voltage alarm threshold
Message value: -
Message class: Infeed faulted (13)
Drive object: B_INF
Reaction: NONE
Acknowledge: NONE
Cause: In operation, the DC link voltage has dropped to below the alarm threshold. The alarm threshold is obtained from the
sum of p0279 and r0296.
Possible causes include:
- line supply voltage dip or another line supply fault.
- overload of the infeed.
- for Active Line Module: Controller incorrectly parameterized.
See also: p0279 (DC link voltage offset alarm threshold), r0296 (DC link voltage undervoltage threshold)
Remedy: - check the line voltage and line supply quality.
- reduce the power drawn, avoid step-like load changes
- for Active Line Module: Adapt the controller parameterization (e.g. automatic line supply identification (p3410 = 4,
5)).
Reaction upon F: NONE (OFF1, OFF2)
Acknowl. upon F: IMMEDIATELY (POWER ON)
A06900 (F) Braking Module: Fault (1 -> 0)
Message value: %1
Message class: Braking Module faulted (14)
Drive object: B_INF
Reaction: NONE
Acknowledge: NONE
Cause: The Braking Module signals a fault (1 -> 0) via X21.4 ("booksize" format) or X21.5 ("chassis" format).
This signal is wired to a system digital input and correspondingly interconnected using binector input p3866[0...7].
Possible causes:
- Wiring of the signal or BICO interconnection of the signal source incorrect.
- Overtemperature
- Electronics power supply missing.
- Ground fault/short-circuit.
- Internal component fault.
See also: p3866 (Braking Module fault)
Remedy: - check binector input p3866[0...7] and the wiring from terminal X21.4 ("booksize" format) or X21.5 ("chassis" format).
- reduce the number of braking operations.
- Check the 24 V power supply of the component.
- Check for a ground fault or short circuit.
- Replace the component if necessary.
Reaction upon F: NONE (OFF2)
Acknowl. upon F: IMMEDIATELY
