Initiation of a "Pulse cancellation".
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 continuation Power-down the control and power-up again.

Axis %1: Checksum error safety monitors. Acknowledgement and
acceptance test required!
Parameter %1 = axis number
Explanation The relevant MDs $MN_SAFE_..., $MN_PROFISAFE_..., $MA_SAFE ... are
protected by a checksum. The alarm indicates that the current checksum is no
longer the same as the stored setpoint checksum, i.e. that an MD value has
either been changed illegally or that data is corrupted.
Response Mode group not ready
Channel not ready
NC start inhibit in this channel
Interface signals are set
Alarm display
NC stop for alarm
Remedy Check MDs. Have the checksum re-calculated. Safety functions should be
subject to a new acceptance test.
Program continuation Power-down the control and power-up again.

%1 = axis number
%2 = machine data label
%3 = machine data index
The parameterization of machine data %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:
- 1. The conversion of the specified MD into the internal computation format
results in an overflow.
- 2. The values entered in MD $MA_SAFE_POS_LIMIT_PLUS
and $MA_SAFE_POS_LIMIT_MINUS have been interchanged.
The upper limit is less than or equal to the lower limit.
- 3. For an axis with safety functions the setpoint/actual value
assignment in MD $MA_SAFE_ENC_SEGMENT_NR,
MD $MA_CTRLOUT_SEGMENT_NR was not made for the drive
bus. No module number was specified for a setpoint /actual value
channel assignment in MD $MA_CTRLOUT_MODULE_NR, MD
$MA_SAFE_ENC_MODULE_NR.
- 4. The number of drives has changed. When reading back the
standstill position and the associated drive number, a difference was
identified to the current drive configuration.
- 5. A safety function was enabled in
MD $MA_SAFE_FUNCTION_ENABLE
without the safety functions SBH/SG having been enabled.
- 6. Error when parameterizing the input/output assignments for the
SGEs/SGAs.
