<location>Power unit: Overvoltage 24 V alarm
Message value:
-
Drive object:
AFE_SINUMERIK_828, BIC_SINUMERIK_828, SERVO_COMBI, SERVO_SINUMERIK828, SIC_COMBI,
SIC_SINUMERIK_828
Reaction:
NONE
Acknowledge:
NONE
Cause:
The following applies for CU31x:
24 V power supply fault for the power unit.
- the 32.0 V threshold was exceeded.
Fault value (r0949):
24 V voltage [1 bit = 0.1 V].
Remedy:
Check the 24 V DC voltage supply to the power unit.

<location>Power unit: Supply undervoltage
Message value:
%1
Drive object:
AFE_SINUMERIK_828, BIC_SINUMERIK_828, SERVO_COMBI, SERVO_SINUMERIK828, SIC_COMBI,
SIC_SINUMERIK_828
Reaction:
OFF2
Acknowledge:
IMMEDIATELY (POWER ON)
Cause:
Power supply fault in the power unit.
- The voltage monitor signals an undervoltage fault on the module.
The following applies for CU31x:
- the voltage monitoring on the DAC board signals an undervoltage fault on the module.
Remedy:
- check the 24 V DC voltage supply to power unit.
- carry out a POWER ON (power off/on) for the component.
- replace the module if necessary.

<location>Power unit: Undervoltage, alarm
Message value:
%1
Drive object:
AFE_SINUMERIK_828, BIC_SINUMERIK_828, SERVO_COMBI, SERVO_SINUMERIK828, SIC_COMBI,
SIC_SINUMERIK_828
Reaction:
NONE
Acknowledge:
NONE
Cause:
Before the last restart, a problem occurred at the power unit power supply.
- the voltage monitor in the internal FPGA of the PSA signals an undervoltage fault on the module.
Fault value (r0949):
Register value of the voltage fault register.
Remedy:
- check the 24 V DC voltage supply to power unit.
- carry out a POWER ON (power off/on) for the component.
- replace the module if necessary.

<location>Cooling system: Cooling medium flow rate too low
Message value:
%1
Drive object:
AFE_SINUMERIK_828, BIC_SINUMERIK_828, SIC_COMBI, SIC_SINUMERIK_828
Reaction:
OFF2
Acknowledge:
IMMEDIATELY
Cause:
Cooling system: Fault - flow rate has fallen below the fault value
