A07805 (N) Drive: Power module I2T overload
Reaction: NONE
Acknowledge: NONE
Cause: Alarm threshold for I2t overload (p0294) of the power module exceeded.
The response parameterized in p0290 becomes active.
See also: p0290
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
Acknowledge NONE
upon N:
F07810 Drive: Power module EEPROM without rated data
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: No rated data are stored in the power module EEPROM.
See also: p0205, r0206, r0207, r0208, r0209
Remedy: Replace the power module or inform Siemens Customer Service.
F07815 Drive: Power module has been changed
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: The code number of the actual power module does not match the saved number.
Fault value (r0949, decimal):
Number of the incorrect parameter.
See also: r0200, p0201
Remedy: Connect the original power module and power-up the control unit again (POWER ON) or set p0201 to r0200 and exit
commissioning with p0010 = 0.
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 module is changed, but also the motor, then the motor must be re-commissioning (e.g. using
p0010 = 1).

A07820 Drive: Temperature sensor not connected
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.
Remedy: - connect the module with temperature sensor.
- set the available temperature sensor (p0600, p0601).
See also: p0600, p0601
F07840 Drive: Infeed operation missing
Reaction: OFF2 (NONE)
Acknowledge: IMMEDIATELY
Cause: The signal "infeed operation" is not present although the enable signals for the drive have been present for longer
than the parameterized monitoring time (p0857).
- infeed not operational.
- interconnection of the binector input for the ready signal is either incorrect or missing (p0864).
Remedy: - bring the infeed into an operational state.
- check the interconnection of the binector input for the signal "infeed operation" (p0864).
- increase the monitoring time (p0857).
