Calculate inv. characteristic
If a motor of a third-party manufacturer with unknown motor parameters is driven by the
controller, the
= "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 "
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 "
" can be used to load a characteristic typical for the device.

• This situation can for instance occur if the motor power is very much lower than the
device power.
