6 Alarms
6.1 Alarms for SINUMERIK 840digital
27005
Axis %1 error for crosswise data comparison: Static actual value
difference
Parameter %1 = axis number
Explanation A difference in the actual values was detected using the crosswise data
comparison between NCK and 611D monitoring channel. This difference is
greater than the maximum tolerance defined in MD $MA_SAFE_POS_TOL.
This can be checked using the safe position actual values of the two monitoring
channels displayed in the service screen.
The alarm is only displayed, if monitoring with absolute reference (SE/SN) has
been enabled for the specified axis and if the user agreement has been set. As
soon as the user agreement is deleted or the actual difference between the two
monitoring channels again drops below the maximum permissible difference,
the alarm is cleared.
Response Alarm display
Remedy The user agreement must be deleted if the alarm is available as a steady-stage
alarm. When the control is then rebooted, the machine can be brought into the
safe state again and operation resumed by a new referencing process and
setting the user agreement. Prior to setting the user agreement, the actual
position of the axis displayed in the "User enable" screen must be compared
with the current machine position. This is obligatory to ensure proper
functioning of the safe limit positions (SE) and safe cams (SN).
The user agreement can only be changed in key-actuated switch setting 3 or
after entering a password.
Program continuation Alarm display disappears with the alarm cause. No further operator action
necessary.
27006
Axis %1 test ext. pulse cancellation running
Parameter %1 = axis number
Explanation The perfect functioning of the external pulse cancellation is presently being
tested by setting the SGE "Test stop external shutdown".
Response Alarm display
Remedy Alarm automatically disappears when the test is terminated by deleting the
SGE "Test stop external shutdown".
Program continuation Alarm display disappears with the alarm cause. No further operator action
necessary.
27007
Axis %1 acceptance test mode is active
Parameter %1 = axis number
Explanation An SI acceptance test has been started with the acceptance test wizard at the
operator panel. The acceptance test mode is activated via the NCK and drive
for the duration of this acceptance test. In the acceptance test mode, SI power
on alarms can be acknowledged with the reset key.
Response Alarm display
Remedy Acceptance test, e.g. de-select using the acceptance test Wizard or wait until it
has been completed (the duration of the acceptance test can be parameterized
using MD $MA_SAFE_ACCEPTANCE_TST_TIMEOUT).
Program continuation Alarm display disappears with the alarm cause. No further operator action
necessary.
