Overview of Alarms
SIMODRIVE 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.
Reaction: 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 Clear alarm with the RESET key. Restart part program
Continuation:
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)
Reaction: 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 correct one of 2 end positions
selected? If the MDs and SGEs are o.k., check the machine for any damage and rectify.
Program Clear alarm with the RESET key. Restart part program
