A01666 (F) SI Motion P1: Steady-state (static) 1 signal at the F-DI for safety-relevant
acknowledgement
Reaction: NONE
Acknowledge: NONE
Cause: A logical 1 signal is present at the F-DI configured in p10006 for more than 10 seconds.
If, at the F-DI no acknowledgment was performed for safe acknowledgment, then a steady-state logical and 0 signal
must be present. This avoids unintentional safety-relevant acknowledgement (or the "Internal Event Acknowledge"
signal) if a wire breaks or one of the two digital inputs bounces.
Remedy: Set the fail-safe digital input (F-DI) to a logical 0 signal (p10006).
Note:
F-DI: Failsafe Digital Input
A01669 (F, N) SI Motion: Unfavorable combination of motor and power unit
Reaction: NONE
Acknowledge: NONE
Cause: The combination of motor and power unit used is not suitable for using safe motion monitoring functions without an
encoder.
The ratio between the power unit rated current (r0207[0]) and rated motor current (p0305) is greater than 5.
Alarm value (r2124, interpret decimal):
Number of the motor data set, which caused the fault.
Notice:
If this alarm is not observed, then message C01711 or C30711 – with the value 1041 ... 1044 – can sporadically
occur.
Remedy: Use a suitable power unit with a lower power rating or a motor with a higher power rating.
F01680 SI Motion P1: Checksum error safety monitoring functions
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The actual checksum calculated by the drive and entered in r9728 via the safety-relevant parameters does not match
the reference checksum saved in p9729 at the last machine acceptance.
Safety-relevant parameters have been changed or a fault is present.
Note:
This fault results in a STOP A that can be acknowledged.
Fault value (r0949, interpret decimal):
0: Checksum error for SI parameters for motion monitoring.
1: Checksum error for SI parameters for actual values.
2: Checksum error for SI parameters for component assignment.
Remedy: - check the safety-relevant parameters and if required, correct.
- execute the function "Copy RAM to ROM".
- perform a POWER ON if safety parameters requiring a POWER ON have been modified.
- carry out an acceptance test.
F01681 SI Motion P1: Incorrect parameter value
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The parameter cannot be parameterized with this value.
Note:
This fault does not result in a safety stop response.
Fault value (r0949, interpret decimal):
yyyyxxxx dec: yyyy = supplementary information, xxxx = parameter
yyyy = 0:
No information available.
xxxx = 9501:
It is not permissible to enable the function "n < nx hysteresis and filtering" (p9501.16) in conjunction with the function
"Extended functions without selection" (p9601.5).
xxxx = 9522:
The gear stage was set too high.
xxxx = 9547:
Parameter p9547 has been set too low.
