F02 

Overvoltage in DC Bus Link

Max. value depends on the set mains voltage

Brake energy too high

"n02" displayed beforehand. Possibly use an external braking resistor or, in the case of multiple amplifiers, connect DC links.

Brake resistor wired incorrect

Check the wiring (see instructions manual). Internal braking resistor: Bridge must be present on the connector!

External braking resistor: Bridge must be removed from the connector!
