SINAMICS V20 Converter
242 Operating Instructions, 10/2019, A5E34559884-012
Displays active status word of converter (in binary) and can be used to diagnose which commands are
active. See r0052 for the bit field description.
P0969
Resettable system run
time counter
0 - 4294967295 0 T - - U32 3
Resettable system run time counter.
P0970 = 1 resets all parameters (not user defaults) to their default values.
P0970 = 21 resets all parameters and all user defaults to Factory Reset state.
When resetting all parameters by setting P0970 = 1 or P0970 = 21, please note the following aspects:
• When you reset parameters through the BOP, parameters in both RAM and EEPROM are reset.
• When you select USS/MODBUS communication on RS485 and the volatile storage mode (P0014[0] =
0), only parameters in RAM are reset.
• When you select USS/MODBUS communication on RS485 and the non-volatile storage mode
(P0014[0] =1), parameters in both RAM and EEPROM are reset.
User Default Parameter Reset
First set P0010 = 30 (factory settings).
Stop converter (i.e. disable all pulses) before you can reset parameters to default values.
The following parameters retain their values after a factory reset:
• r0039 CO: Energy consumption meter [kWh]
• P0014 Store mode
• P0100 Europe/North America
• P0205 Converter application
• P2010 USS/MODBUS baudrate
• P2011 USS address
• P2021 MODBUS address
• P2023 RS485 protocol selection
• P8458 Clone control
When transferring P0970, the converter uses its processor to carry out internal calculations. Communica-
tions are interrupted for the time that it takes to make these calculations.
P0971
Transfer data from RAM
to EEPROM
0 - 21 0 U, T - - U16 3
Transfers values from RAM to EEPROM when set to 1.
Transfers new user default values from RAM to EEPROM when set to 21.
