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.
- Alarm display.
Check settings for safe input signals (NCK I/Os, PLC DB parameters).
Clear alarm with the RESET key. Restart part program
Axis %1 error in data cross check: static actual value difference
%1 = Axis number
Via the data cross check between NCK and 611D monitoring channel, a difference in
actual values was detected, which is greater than the maximum tolerance defined in MD
$MA_SAFE_POS_TOL. This can be checked by means of the safe position values for the
two monitoring channels displayed in the service menu.
The alarm is displayed only, if monitoring with absolute reference (SE/SN) has been
enabled for the specified axis and if the user enable has been set. The alarm is cleared,
as soon as the user enable is deleted or the actual value difference between the two mon-
itoring channels falls again below the maximum permissible difference.
- Alarm display.
If the alarm is present statically, the user enable must be deleted. When the control is
then rebooted, the machine can be brought to the safe state again and operation resumed
by a new referencing process and setting of the user enable. Prior to setting the user
enable, the actual position of the axis displayed in the "User enable" screen must be com-
pared with the current machine position. This is obligatory to ensure the ensure proper
functioning of the safe limit positions (SE) and safe cams (SN).
Alarm display showing cause of alarm disappears. No further operator action
Axis %1 Test ext. pulse deletion running
%1 = Axis number
The correct functioning of the external pulse disable is being checked now by setting the
"Test stop of external shutdown" SGE.
- Alarm display.
