Overview of Alarms
Cause: The drive-based "Safety Integrated" function in the control unit (CU) has detected a fault
and initiated a STOP A (pulse cancellation via the safety shutdown path of the control unit).
- forced checking procedure of the safety shutdown path of the control unit unsuccessful.
- subsequent response to fault F01611 (defect in a monitoring channel).
Note:
This fault results in the following safety stop response dependent on p9501:
- Motion monitoring not enabled (p9501 = 0) --> STOP A that can be acknowledged.
- Motion monitoring not enabled (p9501 = 0) --> STOP A that cannot be acknowledged
(POWER ON).
Fault value (r0949, decimal):
0: Stop request from the motor module.
1005: Pulses cancelled although SH not selected and there is not internal STOP A present.
1010: Pulses enabled although SH is selected or an internal STOP A is present.
1015: Feedback of the safe pulse cancellation for motor modules connected in parallel are
different.
9999: Subsequent response to fault F01611.
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 is also enabled on the motor module (p9801).
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 F01611.
Note:
CU: Control unit
MM: Motor module
SH: Safe standstill
SI: Safety Integrated
201611 <location>SI CU: Defect in a monitoring channel
Reaction: NONE (OFF1, OFF2, OFF3)
Acknowledge: IMMEDIATELY (POWER ON)
