Axis %1, drive %2 checksum error safe monitoring functions –
acknowledgement and acceptance test required!
Parameter %1 = NC axis number
%2 = drive number
Explanation The actual checksum of the safety-relevant MDs calculated by the drive and
saved in MD 1398: $MD_SAFE_ACT_CHECKSUM (display of the checksum of
the machine data for safe functions) has another value than the setpoint
(reference) checksum saved during the last machine acceptance in MD 1399:
$MD_SAFE_DES_CHECKSUM (checksum of the machine data for safety-
related functions). The safety-relevant data has been modified or there is an
error.

Remedy Check all safety-relevant MDs and correct if necessary. Then carry-out a power
on. Carry-out an acceptance test on the machine.
Program continuation Power-down the control and power-up again.
300745 Axis %1, drive %2 limit values for safe end positions exchanged
Parameter %1 = NC axis number
%2 = drive number
Explanation The data for the upper limit for the SE monitoring function contains a lower
value than the data for the lower limit.
Interrogation: When the control runs-up.

Remedy Check the following MDs
MD 1334: $MD_SAFE_POS_LIMIT_PLUS[n] (upper limit value for the safe limit
position) and
MD 1335: $MD_SAFE_POS_LIMIT_MINUS[n] (lower limit value for the safe
limit position) and change so that the upper limit value is greater than the lower
limit value.
Program continuation Power-down the control and power-up again.
300746 Axis %1, drive %2 SBH/SG not enabled
Parameter %1 = NC axis number
%2 = drive number
Explanation In the machine data 1301: $MD_SAFE_FUNCTION_ENABLE (safe functions
enable) the function SBH/SG has not been enabled although the function
SE/SN has been selected in this MD.
Interrogation: When the control runs-up.
