SINAMICS G120 Control Units CU240S, Edition 05/2007
F00395 Acceptance Test / Confirmation pending
Reaction: OFF 2
Acknowledge: Quit fault eg. via DI2
Cause: This fault occurs after a Powermodul (PM) / Control Unit (CU) Swap or a Startup Clone. It can also be caused by a
faulty read from the EEPROM, see F0051 for more details.
The parameterset after a CU swap or a startup clone could have changed and might not match the application.
This parameterset needs to be checked before the drive can start a motor.
• r0949 = 3 / 4: Swap of PM/CU
• r0949 = 5: Startup Clone via MMC has been performed
• r0949 = 10: Before the last power up an acceptance test was pending due to a swap or a startup clone.
Remedy: Safety Units:
An Acceptance Test needs to be performed. Follow the the steps of the Acceptance Log which is part of the Oper-
ating Instructions.
After performing the acceptance test the fault can be acknowledged by the following procedure:
P0010 = 30
P9761 = Safety password
P7844 = 0
The fault will be cleared automatically and P0010 will be set back to 0
Non Safety Units:
The current parameterset needs to be checked and confirmed by clearing the fault or setting P7844 = 0.
F00400 (N) PROFIBUS: DS101/DB101 (control pannel) failure.
Reaction: OFF 2
Acknowledge: Quit fault eg. via DI2
Cause: Timeout, trigger fault,...
Remedy: Restart C2 connection.
F00452 Belt Failure
Reaction: OFF 2 (OFF 3)
Acknowledge: Quit fault eg. via DI2
Cause: Load conditions on motor indicate belt failure or mechanical fault.
• r0949 = 0: trip low torque/speed
• r0949 = 1: trip high torque/speed
Remedy: Check the following:
• No breakage, seizure or obstruction of drive train.
• If using an external speed sensor, check the following parameters for correct function:
• If using the torque envelope, check parameters:
• Apply lubrication if required.
