Program Continuation:

Axis %1 drive %2 safety monitoring checksum invalid, confirmation and acceptance test required!

%1 = NC axis number %2 = Drive number

The actual checksum of the safety-relevant MDs calculated by the drive and stored in MD 1398: $MD_SAFE_ACT_CHECKSUM (display of the checksum of the machine data for safe functions) has another value than the setpoint checksum stored during the last machine acceptance in MD 1399: $MD_SAFE_DES_CHECKSUM (checksum of the machine data for safe functions). The safety-relevant data have been modified or there is an error.
