Overview of Alarms
300914
Axis %1 drive %2 safe velocity exceeded
Parameters: %1 = Axis number
%2 = Drive number
Definitions: The drive is disabled by the reaction configured in MD 1361:
$MD_SAFE_VELO_STOP_MODE. At the end of the stop reaction, the drive remains
under control, the axis is monitored for SBH.
Request: In monitoring cycle.
The axis has moved faster than allowed in machine data MD 1331:
$MD_SAFE_VELO_LIMIT[n] (safe velocity limit values). If the "safe velocity correction"
function is enabled in MD1301: $MD_SAFE_FUNCTION_ENABLE (safe functions
enable), allowance must be made for the correction factor in the velocity limit when using
SG2 and SG4.
Reactions: - NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: Please inform the authorized personnel/service department. Check the input values of the
machine data. Check the safe input signals: is the correct one of four velocity limits
selected?
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
300915
Axis %1 drive %2 safe end positions exceeded
Parameters: %1 = Axis number
%2 = Drive number
Definitions: The drive is disabled by the reaction configured in MD 1362:
$MD_SAFE_POS_STOP_MODE. At the end of the stop reaction, the drive remains
under control, the axis is monitored for SBH.
Request: In monitoring cycle.
The axis has exceeded the limit position which is entered in
• Modify MD 1334: $MD_SAFE_POS_LIMIT_PLUS[n] (upper limit for safe end position)
• Modify MD 1335: $MD_SAFE_POS_LIMIT_MINUS[n] (lower limit for safe end position)
Reactions: - NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: Please inform the authorized personnel/service department. If no obvious operator error
occurred: Check the input value of the machine data and check the SGEs: was the cor-
rect one of 2 end positions selected? If the MDs and SGEs are o.k., check the machine
for any damage and rectify.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
300950
Axis %1 drive %2 is not safely referenced
Parameters: %1 = Axis number
%2 = Drive number
Definitions: No stop reaction is initiated. The message will be present during enabling of the functions
SN/SE until the axis status "Axis safely referenced" has been reached.
Request: In monitoring cycle.
1) The axis is not referenced or
