Cause: The "Safety Integrated" function integrated in the drive has identied a fault
in the self test of the switch-o signal path, and
has initiated an STO (Safe Torque O).
Fault value (r60049, interpret decimal):
1005: STO active, although STO not selected and there is no internal STO active.
1010: STO inactive, although STO is selected or an internal STO is active.
1015: The self test was unsuccessful in operation.
1016: Error in the communication path for brake/F-DI/F-DO/STO
Remedy: - Select STO and then deselect again.
- Carry out a PO
WER ON (switch-o/switch-on) for all components.
- Upgrade software to a later version.
- Contact Technical Support.
C01603 SI: Module temperature - limit value exceeded
Message class: Safety monitoring channel has identied an error (10)
Mes
sage value: -
Variant: S200 PN
Component: None
Response: OFF2
Acknowledgment: IMMEDIATELY
Cause: A safe monitoring function has detected that the module temperature has exceeded a limit value. STO (Safe Torque O)
was
initiat
ed to maintain the safe state.
Remedy: - Check the ambient temperature.
- Check the module fan.
- Oper
ate the module in the permissible range.
F01604 SI: Safety EEPROM data error
Message class: Safety monitoring channel has identied an er
r
or (10)
Mes
sage value: %1
Variant: S200 PN
Component: Control Unit (CU)
Response: OFF2
Acknowledgment: POWER ON
Cause: Safety relevant EEPROM data are not correct.
This mes
sage r
esults in an STO (Safe Torque O).
Message value (r0949, interpret decimal): Only for internal Siemens fault diagnostics.
Remedy: Replace the module.
A01605 SI: Checksum error has occurred
Message class: Safety monitoring channel has identied an error (10)
Mes
sage value: %1
Variant: S200 PN
Component: Control Unit (CU)
Response: NONE
Acknowledgment: NONE
Cause: A checksum error (CRC error) has occurred in the converter program memory.
Alarm v
alue (r2124, interpr
et decimal):
Only for internal Siemens troubleshooting.
