Safe Brake Control - Siemens SINAMICS G120 Operating Instructions Manual

Functions
8.18 Fail-safe functions
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.
*) If PID as trim is active when SS1, SLS0 or SLS1 is triggered, the PID as trim is
deactivated and has no influence to the frequency setpoint at the latest 1 s after the fail-safe
function has been activated.
