F07810 Drive: Power unit EEPROM without rated data
Message value: -
Message class: Hardware / software error (1)
Drive object: B_INF, VECTOR_G
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: No rated data are stored in the power unit EEPROM.
See also: p0205 (Power unit application), r0206 (Rated power unit power), r0207 (Rated power unit current), r0208
(Rated power unit line supply voltage), r0209 (Power unit maximum current)
Remedy: Replace the power unit or inform Siemens Customer Service.
F07815 Drive: Power unit has been changed
Message value: Parameter: %1
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: VECTOR_G
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: The code number of the actual power unit does not match the saved number. This 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 switch on the Control Unit again (POWER ON).
- Set p0201 to r0200 and exit commissioning with p0010 = 0.
Note:
If the power unit type was changed (see r0203) or the motor replaced, then the motor must be recommissioned (e.g.
using p0010 = 1, p3900 = 3, p1900 = 1, 2). This is also necessary if motor data is still to be downloaded via DRIVE-
CLiQ.
If the new power unit is accepted, then if required, the current limit p0640 can be reduced by a lower maximum
current of the power unit (r0209) (torque limits stay the same).
If the comparison stage in p9906 is set to 2, 3, then commissioning can be exited (p0010 = 0) and the fault
acknowledged. This procedure is not recommended for different power unit types.

F07815 Drive: Power unit has been changed
Message value: Parameter: %1
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: B_INF
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: The code number of the actual power unit does not match the saved number. This 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
identification routine (p3410 = 5) must then be carried out. It is not possible to change the power unit without re-
commissioning 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
current of the power unit (r0209) (torque limits stay the same).
