A49173 Cooling unit: Cooling liquid temperature has exceeded the alarm threshold
Message value: -
Message class: Auxiliary unit faulted (20)
Drive object: B_INF, VECTOR_G
Component: None Propagation: GLOBAL
Reaction: NONE
Acknowledge: NONE
Cause: The cooling liquid intake temperature has exceeded the specified alarm threshold.
Note:
The value for the alarm threshold depends on the power unit (hardware description data, e.g. 42 ... 50 °C).
Remedy: Check the cooling system and the ambient conditions.
F49200 Excitation group signal fault
Message value: %1
Message class: General drive fault (19)
Drive object: VECTOR_G
Component: None Propagation: GLOBAL
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: The excitation sequence control signals a fault.
Fault value (r0949, interpret hexadecimal):
Bit 0:
When switched off or when switching off the excitation, the signal "excitation ready feedback signal" was not received
within the monitoring time.
Bit 1:
After an ON command, the signal "excitation ready feedback signal" was not received within the monitoring time.
Bit 2:
After the pulses were enabled, the signal "excitation operational feedback signal" was not received within the
monitoring time.
Bit 3:
The "excitation group signal fault" signal is present.
Bit 4:
The switch-on command for the excitation was reset, although pulse enable (r0899.11) is still available, or the
excitation current actual value has still not fallen below a minimum value.
Note:
This signal can be generated via p6500[59].
Remedy: - check the excitation.
- check commands, feedback signals and BICO interconnections.
- re bit 4: increase the switch-off delay time (p1647).
A49201 (F) Excitation group signal alarm
Message value: -
Message class: General drive fault (19)
Drive object: VECTOR_G
Component: None Propagation: GLOBAL
Reaction: NONE
Acknowledge: NONE
Cause: The "excitation group signal alarm" signal is present.
Note:
This signal can be generated via p6500[58].
Remedy: Check the excitation equipment.
Reaction upon F: NONE
Acknowl. upon F: IMMEDIATELY
