4.2.24 Calculate inv. characteristic
If a motor of a third-party manufacturer with unknown motor parameters is driven by the
controller, the C00002 = "71: Determine inverter characteristic" device command can be used to
determine the so-called "Inverter error characteristic" for optimising the inverter switching
performance.

Tip!
Detailed information about the determination of the inverter error characteristic can be
found in the chapter "Motor interface" in the subchapter " Optimising the switching
performance of the inverter ". ( 135)
From software version V4.0: If the inverter error characteristic cannot be determined by
means of this device command, or if the results of the determination are incorrect, the
device command " Load Lenze INV characteristic " can be used to load a characteristic typical
of the device. ( 69)

• This situation can for instance occur if the motor power is very much lower than the
device power.
• This error message is only available from software version V5.0 onwards.
