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 so set, that the limit frequency
of the limiting frequency of the amplitude monitoring in the measuring circuit hardware
(200 kHz , from SW 4.2 300 kHz up) 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 reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY
(channel not ready).
Pulse blocking (via SGA).
- Mode group not ready.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Please inform the authorized personnel/service department. 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 machine data "MA_SAFE_..." are protected by a checksum after the control has been
accepted. 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 a MD is defective.
Pulse blocking (via SGA).
- Mode group not ready.
- Channel not ready.
- NC Start disable in this channel.
- NC Stop on alarm.
- Alarm display.
- Interface signals are set.
Please inform the authorized personnel/service department. 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 %2 is incorrect. An additional indication is the field index of the
machine data. If the machine data is a single machine data a zero is specified as array
index. This alarm occurs in the following contexts:
