Caution
In SLS modes 0 and 1, the frequency setpoint can increase related to the following functions
• PID Trim
• Vdc max controller
• Slip compensation
• Resonance damping
• Imax
As the frequency is monitored after adding these values, this increasement should be taken
into account by the user when parameterising the safe frequency envelope.
