CAUTION

using functions directly or indirectly influencing

Before personal safety (e.g. Safe Stop, Fire Mode or other functions either forcing the motor to stop or attempting to keep it functioning) a thorough risk analysis and system test must be carried through. The system tests must include testing failure modes regarding the control signaling (analog and digital signals and serial communication.

the functionality of the frequency converter.

A complete set of all parameters controlling the frequency converter is called a set-up. The frequency converter contains 2 set-ups, Set-up 1 and Set-up 2. Furthermore, a fixed set of factory settings can be copied into one or more set-ups.
