A07805 (N) Drive: Power unit overload I2t
Drive object: SERVO, VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: Alarm threshold for I2t overload (p0294) of the power unit exceeded.
The response parameterized in p0290 becomes active.
See also: p0290 (Power unit overload response)
Remedy: - reduce the continuous load.
- adapt the load duty cycle.
- check the assignment of the rated currents of the motor and Motor Module.
Reaction upon N: NONE
Acknowl. upon N: NONE
F07810 Drive: Power unit EEPROM without rated data
Drive object: A_INF, B_INF, SERVO, S_INF, VECTOR
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
Drive object: A_INF, B_INF, SERVO, S_INF, VECTOR
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: The code number of the actual power unit does not match the saved number.
Fault value (r0949, interpret decimal):
Number of the incorrect parameter.
See also: r0200 (Power unit, actual code number), 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:
Commutating 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-com-
missioning 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 module is accepted, then if required, the current limit p0640 can be reduced by a lower maximum
current of the power module (r0209) (torque limits stay the same).
If not only the power unit is changed, but also the motor, then the motor must be re-commissioning (e.g. using p0010
= 1). This is also necessary if motor data is still to be downloaded via DRIVE-CLiQ.

A07820 Drive: Temperature sensor not connected
Drive object: SERVO, VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: The temperature sensor for motor temperature monitoring, specified in p0600, is not available.
- parameter download with "incorrect" setting.
- module with sensor evaluation has been, in the meantime, been removed.
- temperature sensor via Motor Module, not for CU310.
Remedy: - connect the module with temperature sensor.
- set the available temperature sensor (p0600, p0601).
