Faults and Alarms
List of Faults and Alarms
F01659 SI P1: Write request for parameter rejected
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The write request for one or several Safety Integrated parameters on processor 1 was rejected.
Note:
This fault does not result in a safety stop response.
Fault value (r0949, decimal interpretation):
1: The Safety Integrated password is not set.
2: A reset of the drive parameters was selected. However, the Safety Integrated parameters were not reset, as Safety
Integrated is presently enabled.
3: The interconnected STO input is in the simulation mode.
10: An attempt was made to enable the STO function although this cannot be supported.
14: An attempt was made to enable the PROFIsafe communications although this cannot be supported.
15: An attempt was made to enable the motion monitoring functions integrated in the drive although these cannot be
supported.
18: An attempt was made to enable the PROFIsafe function for Basic Functions although this cannot be supported.
20: An attempt was made to simultaneously enable both the drive-integrated motion monitoring functions via
integrated F-DI and STO via terminals, even though these cannot be supported at the same time.
21: An attempt was made to enable the Safety Integrated functions although these cannot be supported by the
connected Power Module.

Remedy: For fault value = 1:
- set the Safety Integrated password (p9761).
For fault value = 2:
- Inhibit Safety Integrated (p9501, p9601) or reset safety parameters (p0970 = 5), then reset the drive parameters
again.
For fault value = 3:
- end the simulation mode for the digital input (p0795).
Re fault value = 10, 14, 15, 18, 20:
- check whether there are faults in the safety function alignment (F01655, F30655) and if required, carry out
diagnostics for the faults involved.
- use a Control Unit that supports the required function.
For fault value = 21:
- use a Power Module that supports the Safety Integrated functions.
Note:
STO: Safe Torque Off

F01660 SI P1: Safety-related functions not supported
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The Power Module does not support the safety-related functions. Safety Integrated cannot be commissioned.
Note:
This fault does not result in a safety stop response.
Remedy: - use a Power Module that supports the safety-related functions.
F01662 Error internal communications
Reaction: OFF2
Acknowledge: POWER ON
Cause: A module-internal communication error has occurred.
Fault value (r0949, interpret hexadecimal):
Only for internal Siemens troubleshooting.
Remedy: - carry out a POWER ON (power off/on).
- upgrade firmware to later version.
- contact the Hotline.
