9) The DC link has either a ground fault or a short-circuit.
10) The precharging circuit is possibly defective (only for chassis units).
See also: p0210 (Drive unit line supply voltage), p0857 (Power unit monitoring time)
Remedy: In general:
- check the line supply voltage at the connecting terminals.
- check the line supply voltage setting (p0210).
- check the monitoring time and, if required, increase (p0857).
- where relevant, observe additional power unit messages/signals (e.g. F30027).
- the following applies to booksize units: Wait (approx. 8 min.) until the precharging resistors have cooled down. For
this purpose, preferably disconnect the infeed unit from the line supply.
For 5):
- carefully observe the permissible precharging frequency (refer to the appropriate Equipment Manual).
For 6):
- check the total capacitance of the DC link and reduce in accordance with the maximum permissible DC link
capacitance if necessary (refer to the appropriate Equipment Manual)
For 7):
- interconnect the ready-for-operation signal from the infeed unit (r0863.0) in the enable logic of the drives connected
to this DC link
For 8):
- check the connections of the external line contactor. The line contactor must be open during DC link fast discharge.
For 9):
- check the DC link for ground faults or short circuits.
F06010 Infeed: Power unit EP 24 V missing in operation
Message value: -
Message class: Infeed faulted (13)
Drive object: B_INF
Component: Power Module
Reaction: OFF2 (OFF1)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: In operation, the pulse enable via terminal EP at the Line Module (X21.3, X21.4) was withdrawn.
Note:
EP: Enable Pulses (pulse enable)
Remedy: - do not open the line side switch in operation - only when the pulses are inhibited.
- check the wiring of terminal EP (X21.3, X21.4) at the Line Module to exclude any poor contacts.
F06100 Infeed: Shutdown due to line supply undervoltage condition
Message value: %1
Message class: Network fault (2)
Drive object: B_INF
Component: None
Reaction: OFF2 (OFF1)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The filtered (steady-state) value of the line supply voltage is less than the fault threshold (p0283).
Fault condition: Vrms < p0283 * p0210
Fault value (r0949, floating point):
Actual steady-state line supply voltage.
Note:
The occurrence of this fault is delayed by the time in p3492. If the fault is removed during this design time, then the
power unit is not tripped (shut down).
Remedy: - check the line supply.
- check the line supply voltage (p0210).
- check the threshold value (p0283).
