• 80 Modulo value for safe cam $MA_SAFE_MODULO_RANGE.
• 81 Velocity tolerance for safe deceleration ramp $MA_SAFE_STOP_VELO_TOL.
• 82 SG override factor SGE 0...15 = active SGE position. -1 = SG override inactive (nei-
ther SG2 nor SG4 active, or function not activated in $MA_SAFE_FUNCTION_ENABLE).
• 83 Acceptance test time different $MA_SAFE_ACCEPTANCE_TST_TIMEOUT.
• 84 Delay time Stop F -> Stop B $MA_SAFE_STOP_SWITCH_TIME_F.
• 85 Delay time pulse disable bus fail $MN_SAFE_PULSE_DIS_TIME_BUSFAIL.
• 86 Not assigned.
• 87 Not assigned.
• 88 Not assigned.
• 89 Encoder limit frequency $MA_SAFE_ENC_FREQ_LIMIT (Performance_2 only).
• 1000 Control timer expired: If one channel informs another of an SGE change, this con-
trol timer is used to check whether the update timer in the other channel has expired.
• 1001 (only assigned on drive, see alarm 300911)
• 1002 User confirmation inconsistent: Data for user confirmation different in both monitor-
ing channels after 2 seconds.
%3 = state of the NCK user acknowledgement.
%4 = state of the 611D user acknowledgement.
• 1003 Reference tolerance $MA_SAFE_REFP_POS_TOL exceeded.
• 1004 Plausibility error in user confirmation.
• 1005 Pulses already disabled on test stop selection.
• 1006 (only assigned on drive, see alarm 300911).
• 1007 (only assigned on drive, see alarm 300911).
• 1008 (only assigned on drive, see alarm 300911).
• 1009 Pulses not disabled after $MA_SAFE_PULSE_DIS_CHECK_TIME test stop time.
• 1010 Pulses not disabled with a test of the external pulse suppression after
$MA_SAFE_PULSE_DIS_CHECK_TIME test stop time.
• 1011 NCK/drive acceptance test state different.
• 1020 Communication disrupted between NCK monitoring channel and drive monitoring
channel.
- NC Start disable in this channel.
- Alarm display.
If safe monitoring was active, STOP B was also triggered automatically. In this case, a
power OFF/ON of the control will be required.
Find the difference between the monitoring channels. Error code %2 shows the cause of
the alarm.
It is possible that safety-relevant machine data are no longer the same (reload if required)
or that the safety-relevant inputs do not have the same level (check).
If an error like that cannot be found, an error in the CPU may have occurred such as a
memory cell that has "fallen over". This error may be temporary (remove with power ON)
or permanent (replace hardware, if it is displayed again after power ON).
Error codes for STOP F for 840D/611D:
0: No error in this channel. Look for the cause in the other channel.
1: Results list 1. Unequal control of the functions via the SGEs; analyze precise error cod-
ing in 611D MD 1391 and 1392.
2: Results list 2. Check cam tolerance, analyze precise error coding in the 611D-MD 1393
and 1394.
3: Actual position. Incorrect encoder evaluation (check MDs). Differently stored standstill
position.
