When the user enable has first been set, follow-up referencing must be carried out each
time the control is booted (with absolute encoders, this follow-up referencing is executed
automatically). This procedure is carried out to verify the standstill position saved prior to
switching off of the control.
Via the MD $MN_SAFE_ALARM_SUPPRESS_LEVEL (MD>=3), the alarm display can
be set in such a way that an alarm is given for each axis individually which has not been
safely referenced.
- Alarm display.
Move all SI axes to known positions and change to "Referencing" mode. Check the posi-
tions on the machine displayed in the user confirmation field and set "User confirmation"
via the selection/toggle key. If the user confirmation for the axes has already been set, ref-
erence the axes again.
Alarm display showing cause of alarm disappears. No further operator action
Axis %1 difference in function safe operational stop, NCK: %2 drive: %3
%1 = Axis number
%2 = Monitoring status safe operating stop
%3 = Monitoring status safe operating stop
During cross-comparison of result list 1 a difference was detected between the NCK and
drive monitoring channels in the status of safe operating stop monitoring.
Safe operating stop: Bit 0,1 in result list 1
Monitoring status:
• OFF = Monitoring is inactive in this monitoring channel
• OK = Monitoring is active in this monitoring channel, limit values are not violated
• L+ = Monitoring is active in this monitoring channel, upper limit exceeded
• L- = Monitoring is active in this monitoring channel, lower limit exceeded
- Alarm display.
Check whether the safe inputs have switched to the same status in both monitoring chan-
nels within the permissible time tolerance.
For further diagnostics, the drive machine data 1391, 1392 and the servo trace signals
"Result list 1, NCK" and "Result list 1, drive" can be used.
Clear alarm with the RESET key. Restart part program
Axis %1 difference in function safe velocity %2, NCK: %3 drive: %4
%1 = Axis number
%2 = SG level for which the difference was determined
%3 = Monitoring status safe velocity
%4 = Monitoring status safe velocity
During cross-comparison of result list 1 a difference was detected between the NCK and
drive monitoring channels in the status of safe velocity monitoring.
• Safe velocity 1: Bit 6, 17.78 cm result list 1
• Safe velocity 2: Bit 8, 22.86 cm result list 1
• Safe velocity 3: Bit 10, 27.94 cm result list 1
• Safe velocity 4: Bit 12, 33.02 cm result list 1
Monitoring status:
• OFF = Monitoring is inactive in this monitoring channel
• OK = Monitoring is active in this monitoring channel, limit values are not violated
• L+ = Monitoring is active in this monitoring channel, upper limit exceeded
• L- = Monitoring is active in this monitoring channel, lower limit exceeded
- Alarm display.
