%2 = Limit value index
%3 = Number of the transmission ratio
%4 = Maximum velocity
Definitions: 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).
Reactions: - 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".
Remedy: Reduce the limit value in MD $MA_SAFE_VELO_LIMIT[x], x = (2nd alarm parameter) - 1,
or correct the setting of the gear factors.
Program Con- Switch control OFF - ON.
tinuation:
27032
Axis %1 checksum error %2 of safe monitoring. Confirmation and re-test required!
Parameters: %1 = Axis number
%2 = Index of $MA_SAFE_ACT_CHECKSUM
Definitions: 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, which means that either an MD value has been
changed without authorization or an MD is defective.
The 2nd parameter indicates the field entry of $MA_SAFE_ACT_CHECKSUM in which
the error was found.
Reactions: - Mode group not ready.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: Check MDs. Allow the checksum to be recalculated. Re-accept safety functions.
Program Con- Switch control OFF - ON.
tinuation:
27033
Axis %1 parameterization of MD %2[%3] invalid
Parameters: %1 = Axis number
%2 = MD identifier
%3 = Machine data index
Definitions: 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. Conversion of the specified MD into the internal calculation format will cause an over-
flow.
