4 Faults and alarms
4.2 List of faults and alarms
SINAMICS G130/G150
1932 List Manual (LH2), 07/2016, A5E03263479A
Remedy: - check the wiring between the cooling unit and the input terminal (Terminal Module).
- check the wiring between the output terminal (Terminal Module) and the cooling system.
- check the external control device for the cooling unit.
F49153 Cooling unit: Liquid flow too low
Message value: -
Message class: Auxiliary unit faulted (20)
Drive object: B_INF, VECTOR_G
Component: None Propagation: GLOBAL
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: The drive converter cooling unit signals that the cooling liquid flow is too low.
- after the ON command, the feedback signal has not been received within the selected starting time (p0260).
- in operation, the feedback signal has failed for longer than the permitted failure time (p0263).
See also: p0260 (Cooling unit starting time 1), p0263 (Cooling unit fault liquid flow delay time), r0267 (Cooling unit
status word)
Remedy: - check the wiring between the cooling unit and the input terminal (Terminal Module).
- check the external control device for the cooling unit.
F49154 (A) Cooling unit: Liquid leak is present
Message value: -
Message class: Auxiliary unit faulted (20)
Drive object: B_INF, VECTOR_G
Component: None Propagation: GLOBAL
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: The liquid leakage monitoring function has responded.
Caution:
If this fault is reparameterized as an alarm, then using other monitoring functions it must be ensured that when
cooling water is lost, the drive is switched off!
See also: r0267 (Cooling unit status word)
Remedy: - check the cooling system for leaks in the cooling circuit.
- check the wiring of the input terminal (Terminal Module) used to monitor leaking fluid.
Reaction upon A: NONE
Acknowl. upon A: NONE
F49155 Cooling unit: Power Stack Adapter, firmware version too old
Message value: -
Message class: Auxiliary unit faulted (20)
Drive object: B_INF, VECTOR_G
Component: None Propagation: GLOBAL
Reaction: OFF2
Acknowledge: POWER ON
Cause: The firmware version in the Power Stack Adapter (PSA) is too old and does not support the liquid cooling.
Remedy: Upgrade the firmware. Check EEPROM data.
F49156 Cooling unit: Cooling liquid temperature has exceeded the fault threshold
Message value: -
Message class: Auxiliary unit faulted (20)
Drive object: B_INF, VECTOR_G
Component: None Propagation: GLOBAL
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: The cooling liquid intake temperature has exceeded the specified fault threshold.
Note:
The value for the fault threshold depends on the power unit (hardware description data, e.g. 52 ... 55 °C).
