ST130 | Initial commissioning – What do I have to observe (motor data)?
Before commissioning a frequency inverter, it is essential that the factory settings are loaded y0.00 = 1.
Then the rated motor data of the motor used are programmed into the inverter. These can be found on the rating plate of your motor.

The required parameters are located in the -b- parameter group. These are the parameters b0.00 to b0.11.
- Nominal voltage (b0.02): 230V (delta connection) / 400V (star connection)
- Nominal frequency (b0.04): 50Hz (for frequencies above 50Hz, adjust F0.08 and F0.10 first)
- Nominal current (b0.03): 3.98A (delta connection) / 2.30A (star connection)
- Nominal speed (b0.05): 1385 rpm
- Rated power (b0.01): 0.75kW
- All other parameters can also be measured by the inverter itself. b0.11 = 2 for rotating measurement without load or b0.11 = 1 for stationary measurement if the load cannot be disconnected. If possible, always carry out a rotating measurement without load, this leads to more accurate values.
