Power Unit: Overload I2T; Power Unit: Thyristor Control Board; Power Unit: Sign-Of-Life Error Cyclic Data - Siemens Sinamics S120 Diagnostic Manual

230005 <location>Power unit: Overload I2t
Message value: %1
Drive object: AFE_SINUMERIK_828, BIC_SINUMERIK_828, SERVO_COMBI, SERVO_SINUMERIK828, SIC_COMBI,
SIC_SINUMERIK_828
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: The power unit was overloaded (r0036 = 100 %).
- the permissible rated power unit current was exceeded for an inadmissibly long time.
- the permissible load duty cycle was not maintained.
Fault value (r0949, interpret decimal):
I2t [100 % = 16384].
Remedy: - reduce the continuous load.
- adapt the load duty cycle.
- check the motor and power unit rated currents.

SIC_SINUMERIK_828
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: The Thyristor Control Board (TCB) of the Basic Line Module signals a fault.
- there is no line supply voltage.
- the line contactor is not closed.
- the line supply voltage is too low.
- line supply frequency outside the permissible range (45 ... 66 Hz).
- there is a DC link short-circuit.
- there is a DC link short-circuit (during the pre-charging phase).
- voltage supply for the Thyristor Control Board outside the nominal range (5 ... 18 V) and line voltage >30 V.
- there is an internal fault in the Thyristor Control Board.
Remedy: The faults must be saved in the Thyristor Control Board and must be acknowledged. To do this, the supply voltage of
the Thyristor Control Board must be switched out for at least 10 s!
- check the line supply voltage
- check or energize the line contactor.
- check the monitoring time and, if required, increase (p0857).
- if required, observe additional power unit messages/signals.
- check the DC link regarding short-circuit or ground fault.
- evaluate diagnostic LEDs for the Thyristor Control Board.

Message value: -
Drive object: AFE_SINUMERIK_828, BIC_SINUMERIK_828, SERVO_COMBI, SERVO_SINUMERIK828, SIC_COMBI,
SIC_SINUMERIK_828
Reaction: Servo: NONE (OFF1, OFF2, OFF3)
Infeed: NONE (OFF1, OFF2)
Acknowledge: IMMEDIATELY
Cause: The power unit has detected that the cyclic setpoint telegrams of the Control Unit have not been updated on time. The
number of consecutive sign-of-life errors has exceeded the fault threshold (p7789).
