F30611 SI P2: Defect in a monitoring channel
1 to 999: Number of the crosswise compared data that resulted in this fault. This number is also displayed
in r9895.
1: SI monitoring clock cycle (r9780, r9880)
2: SI enable safety functions (p9601, p9801). Only the supported bits are crosswise compared.
3: SI SGE changeover, tolerance time (p9650, p9850)
4: SI transition time STOP F to STOP A (p9658, p9858)
5: SI enable Safe Brake Control (p9602, p9802)
6: SI Motion, enable safety functions (p9501, internal value).
7: SI delay time of STO for Safe Stop 1 (p9652, p9852).
9: Debounce time for STO/SBC/SS1 (MM) (p9651, p9851)
10: SI delay time to initiate STO for ESR (p9697, p9897)
11: SI Safe Brake Adapter mode, BICO interconnection (p9621, p9821).
1000: Check (watchdog) timer has expired. Within the time of approx. 5 x p9850 too many signal changes
have occurred at terminal EP of the Motor Module.
1001, 1002: Initialization error, change timer/check timer.
1950: Module temperature outside the permissible temperature range.
1951: Module temperature not plausible.
2000: Status of STO selection in both monitoring channels different.
2001: Feedback signal of STO deactivation in both monitoring channels different.
2002: Status of the delay timer SS1 in both monitoring channels different (status of the timer in p9650/p9850).
2003: Status of the STO terminals in both monitoring channels different.
Remedy
● For fault value = 1 to 5 and 7 to 999:
Check the crosswise compared data that resulted in a STOP F.
Carry out a POWER ON (power off/on) for all components.
Upgrade the Motor Module software.
Upgrade the Control Unit software.
● For fault value = 6:
Carry out a POWER ON (power off/on) for all components.
Upgrade the Motor Module software.
Upgrade the Control Unit software.
● For fault value = 1000:
Check the wiring of the safety-related inputs (SGE) on the Control Unit (contact problems).
● For fault value = 1001, 1002:
Carry out a POWER ON (power off/on) for all components.
Upgrade the Motor Module software.
Upgrade the Control Unit software.
● Re fault value = 2000, 2001, 2002, 2003:
Check the tolerance time SGE changeover and if required, increase the value (p9650, p9850, p9652/
p9852).
Check the wiring of the safety-related inputs (SGE) (contact problems).
Check the reason why STO was selected in r9872. For active SMM functions (p9501 = 1), STO can also
be selected as a result of these functions.
Replace the Motor Module involved.
This fault can be acknowledged after resolving the cause of fault and after selecting/deselecting STO.
