Axis %1 limit value for safe velocity %2 at gear ratio %3 too large (max. %4)
%1 = Axis number
%2 = Limit value index
%3 = Number of the transmission ratio
%4 = Maximum velocity
All limit values in MD $MA_SAFE_VELO_LIMIT have to be set in a way that the limit fre-
quency of the amplitude monitoring in the measuring circuit hardware is not exceeded.
The limit value which did not fulfil this condition is indicated as second parameter (1 for
SG1, 2 for SG2, etc.). The third parameter indicates the gear stage, e.g. 1 for gear stage
1, 2 for gear stage 2, etc. The fourth parameter indicates the maximum velocity which can
be entered to just maintain the limit frequency in safe operation. The alarm can be repro-
grammed in the MD ALARM_REACTION_CHAN_NOREADY (channel not ready).
- Mode group not ready.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Trigger a "Pulse suppression".
Reduce the limit value in MD $MA_SAFE_VELO_LIMIT[x], x = (2nd alarm parameter) - 1,
or correct the setting of the gear factors.
Switch control OFF - ON.
Axis %1 checksum error of safe monitoring. Confirmation and re-test required!
%1 = Axis number
The relevant MDs $MN_SAFE_..., $MN_PROFISAFE_..., $MA_SAFE ... are protected by
a checksum. The alarm indicates that the current checksum does not coincide any longer
with the stored checksum, that means that either an MD value has been changed without
authorization or an MD is defective.
- Mode group not ready.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Check MDs. Allow the checksum to be recalculated. Re-accept safety functions.
Switch control OFF - ON.
Axis %1 parameterization of MD %2[%3] invalid
%1 = Axis number
%2 = MD identifier
%3 = Machine data index
The parameterization of machine data %2 is incorrect. An additional indication is the array
index of the machine data. If the machine data is a single machine date, a zero is speci-
fied as array index. This alarm occurs in the following contexts:
• 1. The conversion of the specified MD into the internal calculation format will cause an
overflow.
• 2. The values entered in MD $MA_SAFE_POS_LIMIT_PLUS und
$MA_SAFE_POS_LIMIT_MINUS have been interchanged. The upper limit is less than or
equal to the lower limit.
