Overview of Alarms
Remedy: Enable SBH/SG (p9501.0) and carry-out a POWER ON.
Note:
SBH: Safe operating stop
SG: Safely-reduced speed
SI: Safety Integrated
See also: p9501
201684 <location>SI motion: Safe software limit switch limit values interchanged
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: For the function "safe software limit switch" (SE), a lower value is in p9534 as in p9535.
Note:
This fault results in a STOP A that cannot be acknowledged.
Fault value (r0949, decimal):
1: Limit values SE1 interchanged.
2: Limit values SE2 interchanged.
Remedy: Correct the limit values in p9534 and p9535 and carry-out a POWER ON.
Note:
SE: Safe software limit switch
SI: Safety Integrated
201685 <location>SI motion: Safe velocity limit value too high
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The limit value for the function "safely reduced speed" (SG) is greater than the speed that
corresponds to an encoder limit frequency of 500 kHz.
Fault value (r0949, decimal):
Maximum permissible speed.
Remedy: Correct the limit values for SG and carry-out a POWER ON.
Note:
SG: Safely-reduced speed
SI: Safety Integrated
See also: p9531
201686 <location>SI motion: Illegal parameterization, cam position
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: At least one enabled "safety software cam" (SN) is parameterized in p9536 or p9537 too
close at the tolerance range around the modulo position.
Fault value (r0949, decimal):
Number of the "safe software cam" with an illegal position.
See also: p9501
Remedy: Correct the cam position and carry-out a POWER ON.
Note:
SI: Safety Integrated
SN: Safe software cams
See also: p9536, p9537
201687 <location>SI motion: Illegal parameterization, modulo value SN
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The parameterized modulo value for the "safe software cams" (SN) function is not a
multiple of 360 000 mDegrees.
