Axis %1, drive %2 safe end positions exceeded
Parameter %1 = NC axis number
%2 = drive number
Explanation The drive is stopped using the response configured in MD 1362:
$MD_SAFE_POS_STOP_MODE. At the end of the stop response, the drive
remains in closed-loop control, the axis is monitored for SBH.
Interrogation: In the monitoring clock cycle.
The axis has exceeded the limit position (i.e. endstop) that is entered in
• MD 1334: $MD_SAFE_POS_LIMIT_PLUS[n] (upper limit for safe limit
position)
• MD 1335: $MD_SAFE_POS_LIMIT_MINUS[n] (lower limit for safe limit
position)
Response NC start inhibit in this channel
NC stop for alarm
Alarm display
Interface signals are set
Remedy Please inform the authorized personnel/service department.
If no obvious operator error occurred: Check the SGEs: Was the correct one of
2 limit positions selected? If the MDs and SGEs are o.k., check the machine for
any damage and repair.
Program continuation Clear the alarm with the RESET key. Restart part program.
300950 Axis %1, drive %2 Axis not safely referenced
Parameter %1 = NC axis number
%2 = drive number
Explanation No stop response is initiated. When the SN/SE functions are enabled, the
message remains until the axis state "Axis safely referenced" has been
reached.
Interrogation: In the monitoring clock cycle.
1.) Axis is not safely referenced or
2.) User agreement for this axis is missing or has been withdrawn. This can
occur, for example, if the axis was moved after the machine was powered-down
and the standstill position that was saved is therefore no longer correct.
This message prompts the user to confirm the actual position. To do this, you
must determine the position, e.g. as follows:
• Measure the position.
• Move to a known position.
Response Alarm display
Remedy Please inform the authorized personnel/service department.
If the axis cannot be automatically and safely referenced, then the user must
enter a "user agreement" for the new position using the appropriate softkey.
This user agreement identifies this position as safe - that means the axis status
"Axis safely referenced" is reached.
Warning:
If the axis has not been safely referenced and the user has not issued a user
agreement, then the following applies:
- The safe cams are active, but not yet safe
- The safe limit positions are not yet active
Program continuation Alarm display disappears with alarm cause. No further operator action
necessary.
