F05064 Parallel connection: Pulse synchronization error
Message value: -
Message class: General drive fault (19)
Drive object: VECTOR_G
Reaction: OFF2 (OFF1, OFF3)
Acknowledge: POWER ON (IMMEDIATELY)
Cause: The pulse synchronization of at least one of the power units connected in parallel is incorrect.
Remedy: Restart the drive system.
A05065 (F, N) Voltage measured values not plausible
Message value: %1
Message class: Power electronics faulted (5)
Drive object: VECTOR_G
Reaction: NONE
Acknowledge: NONE
Cause: The voltage measurement does not supply any plausible values and is not used.
Alarm value (r2124, interpret bitwise binary):
Bit 1: Phase U
Bit 2: Phase V
Bit 3: Phase W
Remedy: The following parameterization must be made in order to deactivate the alarm:
- Deactivate voltage measurement (p0247.0 = 0).
- Deactivate flying restart with voltage measurement (p0247.5 = 0) and deactivate fast flying restart (p1780.11 = 0).
Reaction upon F: NONE (OFF1, OFF2, OFF3, STOP2)
Acknowl. upon F: IMMEDIATELY
Reaction upon N: NONE
Acknowl. upon N: NONE
F05118 (A) Pre-charging contactor simultaneity monitoring time exceeded
Message value: fault cause: %1, additional information: %2
Message class: Infeed faulted (13)
Drive object: B_INF, VECTOR_G
Reaction: OFF2 (NONE, OFF1)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: A feedback signal for the pre-charging contactor (ALM, SLM, BLM diode) or the line contactor (BLM thyristor)
interconnected and the simultaneity monitoring (p0255[4, 6]) activated.
After opening or closing a contactor of the parallel connection, after a monitoring time has elapsed, not all of the
contactors have assumed the same state.
Fault value (r0949, interpret binary):
Bit 0 = 1: simultaneity error when closing the contactors.
Bit 1 = 1: simultaneity error when opening the contactors.
Bit 16 = 1: PDS0 contactor is closed.
Bit 17 = 1: PDS1 contactor is closed.
Bit 18 = 1: PDS2 contactor is closed.
Bit 19 = 1: PDS3 contactor is closed.
Bit 20 = 1: PDS4 contactor is closed.
Bit 21 = 1: PDS5 contactor is closed.
Bit 22 = 1: PDS6 contactor is closed.
Bit 23 = 1: PDS7 contactor is closed.
Note:
PDS: Power unit Data Set
Remedy: - check the monitoring time setting (p0255[4, 6]).
- check the contactor wiring and activation.
- if required, replace the contactor.
