Checksum error occurred %1 %2
Parameter %1 = reference to the code section or table
%2 = table number
Explanation Checksum error in safety-relevant code or safety-relevant data. The safe
monitoring (Safety Integrated) in the NCK could be damaged.
Response Alarm display
Remedy Only continue with the work with increased caution. Reload code and data as
soon as possible (power on). If this error occurs again, contact your service
personnel.
Program continuation Power-down the control system and power-up again.

Axis %1, difference safe input %2, NCK %3, drive %4
Parameter %1 = axis number
%2 = monitoring involved
%3 = interface label, NCK input
%4 = interface label, drive input
Explanation A difference has been found at the specified safe input. The state of the
specified input signal differed in the two monitoring channels NCK and 611D
during the time set in $MA_SAFE_MODE_SWITCH_TIME.

Interface label, NCK input (%3):
DMP<drv><mod><bit>=<value>
<drv> = drive number of the terminal block (1...31)
<mod> = sub-module number (1...8)
<bit> = connection number (1...16)
<value> = value of the NCK-SGE (0,1)
SPL for the case that SGE is parameterized at the SPL interface.
<io> = parameterized system variable range (01=$A_INSID, 02=$A_INSED)
<dword> = system variable double word (1,2)
<bit> = bit number in the system variable double word (1...32)
<value> = value of the NCK-SGE (0,1)
Onboard input - for the case that the SGE is parameterized at an onboard
input.
<bit> = input number = 01 ...04
<value> = value of the NCK-SGE = 0,1
Interface label, drive input (%4):
DBX<byte><bit>=<value>
<byte> = byte number in the axial DB (22, 23, 32, 33)
<bit> = bit number in the byte (0...7)
<value> = value of the drive SGE (0,1)
This alarm can be hidden using the MD $MN_SAFE_DIAGNOSIS_MASK, Bit
0=0.
Response Alarm display
Remedy Check settings for safe input signals (NCK I/Os, PLC DB parameters).
Program continuation Clear the alarm with the RESET key. Restart part program.
