Infeed: Power Unit Overload I2T; Drive: Power Unit Eeprom Without Rated Data; Drive: Power Unit Has Been Changed - Siemens Sinamics S120 Diagnostic Manual

SINAMICS alarms
207805 <location>Infeed: Power unit overload I2t
Message value: -
Drive object: AFE_SINUMERIK_828, BIC_SINUMERIK_828, SIC_COMBI, SIC_SINUMERIK_828
Reaction: NONE
Acknowledge: NONE
Cause: Alarm threshold for I2t overload (p0294) of the power unit exceeded.
Remedy: - reduce the continuous load.
- adapt the load duty cycle.
207810 <location>Drive: Power unit EEPROM without rated data
Message value: -
Drive object: AFE_SINUMERIK_828, BIC_SINUMERIK_828, SERVO_COMBI, SERVO_SINUMERIK828, SIC_COMBI,
SIC_SINUMERIK_828
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: No rated data are stored in the power unit EEPROM.
See also: r0206 (Rated power unit power), r0207 (Rated power unit current), r0208 (Rated power unit line supply volt-
age), r0209 (Power unit, maximum current)
Remedy: Replace the power unit or inform Siemens Customer Service.
207815 <location>Drive: Power unit has been changed
Message value: Parameter: %1
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: The code number of the actual power unit does not match the saved number. The fault only occurs if the comparator
in p9906 or p9908 is not at 2 (low) or 3 (minimum).
Fault value (r0949, interpret decimal):
Number of the incorrect parameter.
See also: r0200 (Power unit code number actual), p0201 (Power unit code number)
Remedy: Connect the original power unit and power up the Control Unit again (POWER ON) or set p0201 to r0200 and exit
commissioning with p0010 = 0.
For infeeds, the following applies:
Line reactors or line filters must be used that are specified for the new power unit. A line supply and DC link identifi-
cation routine (p3410 = 5) must then be carried out. It is not possible to change the power unit without re-commission-
ing the system if the type of infeed (A_Infeed, B_Infeed, S_Infeed), the type of construction/design (booksize, chassis)
or the voltage class differ between the old and new power units.
For inverters, the following applies:
If the new power unit is accepted, then if required, the current limit (p0640) can be reduced by a lower maximum cur-
rent of the power unit (r0209) (torque limits stay the same).
If not only the power unit is changed, but also the motor, then the motor must be re-commissioned (e.g. using p0010
= 1). This is also necessary if motor data is still to be downloaded via DRIVE-CLiQ.
If the comparison stage in p9906 is set to 2, 3, then commissioning can be exited (p0010 = 0) and the fault acknowl-
edged.
