Remedy: Motion monitoring not enabled (p9501 = 0):
- select safe standstill and then de-select again.
Motion monitoring enabled (p9501 > 0):
- carry-out a POWER ON.
Independent of the motion monitoring enable:
- check whether the "safe standstill" function on the control unit (CU) is enabled (p9601). If
required, select the safety commissioning mode (p0010), enable the "safe standstill"
function on the control unit and motor module (p9601, p9801), exist the safety
commissioning mode (p0010) and carry-out a POWER ON for all components (power-
down/power-up).
- replace the motor module involved.
Re fault value = 9999:
- carry-out diagnostics for fault F30611.
Note:
CU: Control unit
MM: Motor module
SH: Safe standstill
SI: Safety Integrated
230611 <location>SI MM: Defect in a monitoring channel
Reaction: NONE (OFF1, OFF2, OFF3)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The drive-based "Safety Integrated" function in the motor module (MM) has detected a
fault in the crosswise data comparison between the control unit (CU) and MM and initiated
a STOP F.
As a result of this fault, after the parameterized transition has expired (p9858), fault F30600
(SI MM: STOP A initiated) is output.
Fault value (r0949, decimal):
0: Stop request from the control unit.
1 to 999:
Number of the crosswise compared data that resulted in this fault.
1: SI monitoring clock cycle (r9780, r9880).
2: SI enable safety functions (p9601, p9801).
3: SI SGE changeover tolerance time (p9650, p9850).
4: SI transition period STOP F to STOP A (p9658, p9858).
5: SI enable safe brake control (p9602, p9802).
6: SI motion enable, safety-relevant functions (p9501, internal value). This number is also
displayed in r9895.
1000: Watchdog timer has expired. Within the time of approx. 5 * p9850 too many switching
operations have occurred at the safety-related inputs of the control unit.
1001, 1002: Initialization error, change timer / check timer.
2000: Status of the SH terminals on the control unit and motor module are different.
2001: Feedback signal for safe pulse cancellation on the control unit and motor module are
different.
