SINAMICS G120 Control Units CU240S, Edition 05/2007
F01649 Internal software error
Reaction: OFF 2 (OFF 3)
Acknowledge: Quit fault eg. via DI2
Cause: • r0949 = 1: Buffer overflow on checksum calculation for P1 parameter access functions.
• r0949 = 2: Buffer overflow on checksum calculation for P2 parameter access functions.
• r0949 = 3: Endless safety loop on P1.
• r0949 = 4: Endless safety loop on P2.
• r0949 > 100: Signal an internal or unexpected software fault.
Only for Siemens internal diagnostics.
Remedy: Contact hotline.
F01650 Fault in safety parametr.
Reaction: OFF 2 (OFF 3)
Acknowledge: Quit fault eg. via DI2
Cause: Error during startup or safety commissioning/reset:
• r0949 = 0: Error during safety commissioning/reset.
• r0949 = 1: Checksum error during safety commissioning or safety reset.
• r0949 = 2: Error during internal parameter transfer.
• r0949 = 3: Error finalizing the buffer transfer.
• r0949 = 4: Failure during saving of parameters to EEPROM.
• r0949 = 5: Error in safety parameter transfer during safety reset.
• r0949 = 11: Communication channel between processors not ready.
• r0949 =2000: Safety commissioning can only be finished by setting parameter p3900.
Remedy: • Perform safety commissioning.
• Try leaving via p3900 = 11.
F01655 Fault at processor reset
Reaction: OFF 2 (OFF 3)
Acknowledge: Quit fault eg. via DI2
Cause: • r0949 = 100: Safety reset timeout on P1.
• r0949 = 200: Safety reset timeout on P2.
Remedy: • Retrigger the safety reset (perform a hot swap of the inverter module).
F01659 Denial of paramet. change
Reaction: OFF 2 (OFF 3)
Acknowledge: Quit fault eg. via DI2
Cause: A write request for one or more safety parameters was rejected:
• r0949 = 0: Problem during finalization of safety parameters. Drive has reloaded the old data.
• r0949 = 1: Safety password not set correctly.
• r0949 = 3: Tolerance too small (p9691 < p9690). Increase tolerance p9691!
• r0949 = 203: Tolerance too small (p9891 < p9890). Increase tolerance!
Remedy: • Acknowledge fault and enter safety commissioning again. If not possible, leave the safety commissioning with
p3900 = 11 and operate the drive with the old safety settings.
F01660 Wrong safety checksum
Reaction: OFF 2 (OFF 3)
Acknowledge: Quit fault eg. via DI2
Cause: • r0949 = 0: Attempt to leave safety commissioning with r9798 != p9799.
• r0949 = 1: Attempt to leave safety commissioning with r9898 != p9899.
• r0949 = 2: Attempt to leave safety commissioning with r9798 != r9898.
Remedy: • Make sure that checksums in p9798 and p9898 are identical. If not, ensure that parametrisation is identical
(p96xx = p98xx).
• Set checksum in p9799 or p9899 correctly.
• If setting the checksums not successful, leave safety commissioning via p3900 = 11 (cancel commissioning).
