The alarm will disappear automatically after expiry of the delay time - defined in MD
$MA_SAFE_PULSE_DIS_CHECK_TIME - and after removal of SGE "Test stop selec-
tion", if the control recognizes pulse suppression, i.e. the test has been completed suc-
cessfully. An unsuccessful test can be recognized by alarm 27001 with error code 1005 or
by alarm 27024.
27003
Checksum error found: %1 %2
Parameters: %1 = Note on code section or table
%2 = Table number
Definitions: Checksum error in safety-relevant code or safety-relevant data. The safe monitoring func-
tions (Safety Integrated) in the NCK could be affected.
Reactions: - Alarm display.
Remedy: Continue to work very carefully. Reload code and data as soon as possible (Power On). If
this error occurs again, contact your service personnel.
Program Con- Switch control OFF - ON.
tinuation:
27004
Axis %1, difference safe input %2, NCK %3, drive %4
Parameters: %1 = Axis number
%2 = Monitoring input
%3 = Interface identifier NCK input
%4 = Interface identifier drive input
Definitions: A difference has been found on the specified safe input. The state of the specified input
signal differed in the two monitoring channels NCK and 611D during the duration set in
$MA_SAFE_MODE_SWITCH_TIME.
Monitoring in question (%2):
SS/SV = Difference in SGE "Deselection of safe operating stop/Safe velocity"
SS = Difference in SGE "Safe operating stop"
SV = Difference in SGE "Selection safe velocity"
SP = Difference in SGE "Selection safe limit position"
SVOVR = Difference in SGEs "Selection SG correction"
Interface identifier NCK input:
DMP<drv><mod><bit>=<value>
<drv> = Drive number of terminal block (1...31)
<mod> = Submodule number (1...8)
<bit> = Terminal number (1...16)
<value> = Value of NCK SGE (0,1)
SPL For when the SGE is parameterized at the SPL interface.
<io> = Parameterizable system variable range (01=$A_INSID, 02=$A_INSED)
<dword> = System variable double word (1,2)
<bit> = Bit number in system variable double word (1...32)
<value> = Value of NCK SGE (0,1)
Onboard input For when the SGE is parameterized at an onboard input.
<bit> = Input number = 01 ...04
<value> = Value of NCK SGE = 0,1
Interface identifier drive input:
DBX<byte><bit>=<value >
<byte> = Byte number in axial DB (22, 23, 32, 33)
<bit> = Bit number in byte (0...7)
<value> = Value of drive SGE (0,1)
This alarm can be hidden by setting MD $MN_SAFE_DIAGNOSIS_MASK, bit 0 = 0.
