Remedy: - reduce the continuous load.
- adapt the load duty cycle.
- check the assignment of the rated currents of the motor and Motor Module.
207810 <location>Drive: Power unit EEPROM without rated data
Message -
value:
Drive object: A_INF, B_INF, S_INF, SERVO, VECTOR
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: No rated data are stored in the power unit EEPROM.
See also: p0205, r0206, r0207, r0208, r0209
Remedy: Replace the power unit or inform Siemens Customer Service.
207815 <location>Drive: Power unit has been changed
Message Parameter: %1
value:
Drive object: A_INF, B_INF, S_INF
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: The code number of the current power unit does not match the saved number. The fault only occurs
if the comparator in p9906 or p9908 is not at f 2 (low) or 3 (minimum).
Fault value (r0949, interpret decimal):
Number of the incorrect parameter.
See also: r0200 (Power unit current 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 sup-
ply 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).
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.
