Cause: The drive-based "Safety Integrated" function in the control unit (CU) has detected a fault in
the crosswise data comparison between the CU and motor module (MM) and initiated a
STOP F.
As a result of this fault, after the parameterized transition has expired (p9658), fault F01600
(SI CU: STOP A initiated) is output.
Fault value (r0949, decimal):
0: Stop request from the motor module.
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 r9795.
1000: Watchdog timer has expired. Within the time of approx. 5 * p9650 too many switching
operations have occurred at terminal EP of the motor module.
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.
2004: Status of the SH selection for modules connected in parallel are different.
2005: Feedback signal of the safe pulse cancellation on the control unit and motor modules
connected in parallel are different.
Remedy: Re fault value = 1 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.
Re fault value = 1000:
- check the EP terminal at the motor module (contact problems).
Re 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, 2004, 2005:
- check the tolerance time SGE changeover and if required, increase the value (p9650,
p9850).
- check the wiring of the safety-relevant inputs (SGE) (contact problems).
- replace the motor module involved.
Note:
CU: Control unit
EP: Enable Pulses (pulse enable)
MM: Motor module
SGE: Safety-relevant input
SH: Safe standstill
SI: Safety Integrated
201620 <location>SI CU: Safe standstill active
Reaction: NONE
Acknowledge: NONE
Cause: The "safe standstill" function has been selected on the control unit (CU) and is active.
Note:
This message does not result in a safety stop response.
