-- OK = monitoring active in this monitoring channel, limit values not
violated
-- L+ = monitoring active in this monitoring channel, upper limit value
violated
-- L-- = monitoring active in this monitoring channel, lower limit value

A STOP F was initiated. If a safety monitoring function was active, then
a STOP B was also automatically initiated. It is then necessary to
power--down the control and power it up again (power on).
Check that the safe inputs in both monitoring channels have switched
into the same state within the permissible time tolerance.
For further diagnostics refer to the drive parameters r9710[0], r9710[1]
and the servo--trace signals "result list 1 NCK" and "result list 1 drive".
Clear the alarm with the RESET key. Restart the part program.
Axis %1, difference in safe limit position function %2,
drive: %4
%1 = axis name, spindle number
%2 = number of the SE limit
%3 = monitoring status, safe limit position
%4 = monitoring status, safe limit position
In the crosswise data comparison of result list 1 between the NCK and
drive monitoring channels, a difference was detected in the monitoring
state of the safe limit position monitoring.
-- Safe limit position 1: Bits 2, 3 in result list 1
-- Safe limit position 2: Bits 4, 5 in result list 1
Displayed monitoring status (NCK/drive (%3, %4)):

-- OK = monitoring active in this monitoring channel, limit values not
violated
