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 suitable interconnected.
Reaction upon A: NONE
Acknowl. upon A: NONE
A06800 (F) Infeed: Maximum steady-state DC link voltage reached
Drive object: A_INF, B_INF, S_INF
Reaction: NONE
Acknowledge: NONE
Cause: The DC link voltage setpoint has reached the maximum steady-state voltage parameterized in p0280.
The DC link voltage is increased by the modulation depth reserve controller for the following reasons:
- modulation depth reserve is too low (p3480).
- line supply voltage is too high.
- supply voltage (p0210) parameterized to be too low.
- excessively high setpoint for the reactive line current.
Remedy: - check the line supply voltage setting (p0210).
- check the line supply for an overvoltage condition.
- reduce the modulation depth reserve (p3480).
- reduce the reactive current setpoint.

ulation depth limit)
Reaction upon F: NONE (OFF1, OFF2)
Acknowl. upon F: IMMEDIATELY (POWER ON)
A06810 (F) Infeed: DC link voltage alarm threshold
Drive object: A_INF, B_INF, S_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 ALM: Incorrect controller parameterization
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 ALM: Adapt the controller parameterization, e.g. using an 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)
Drive object: A_INF, B_INF, S_INF
Reaction: NONE
Acknowledge: NONE
Cause: The Braking Module signals "Fault (1 -> 0)" via terminal X21.4.
This signal is interconnected via binector input BI: p3866[0...7].
See also: p3866 (Braking Module fault)
Remedy: - reduce the number of braking operations.
- check binector input BI: p3866[0...7] and the wiring from terminal X21.4 of the particular braking module.
Reaction upon F: NONE (OFF2)
Acknowl. upon F: IMMEDIATELY
