Siemens SINAMICS G120C User Manual

Suppressing the automatic restart only functions for the setting p1210=6, 16 or 26.
Note
Motor starts in spite of an OFF command via the 󹪝eldbus
The converter responds with a fault if 󹪝eldbus communication is interrupted. For one of the
settings p1210 = 6, 16 or 26, the converter automatically acknowledges the fault and the motor
restarts, even if the higher-level control attempts to send an OFF command to the converter.
• In order to prevent the motor automatically starting when the 󹪝eldbus communication fails,
you must enter the fault number of the communication error in parameter p1206.

8.30 Kinetic bu󹪜ering (Vdc min control)
Overview
Kinetic bu󹪜ering increases the drive availability. The kinetic bu󹪜ering utilizes the kinetic
energy of the load to bu󹪜er line dips and failures. During a line dip, the converter keeps the
motor in the switched-on state for as long as possible. One second is a typical maximum
bu󹪜er time.
Requirement
The following requirements must be ful󹪝lled to practically use the "kinetic bu󹪜ering" function:
• The driven machine has a su󹪟ciently high inertia.
• The application allows a motor to be braked when the line supply fails.
