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/power--up the control (power on).
Drive parameters r9711[0,1] (diagnostics, result list 2 [NCK, drive]) or
r9735[0,1] / r9736[0,1] / r9737[0,1] /r9738[0,1] / r9739[0,1] (diagnostics,
result list 3/4/5/6/7 [NCK, drive]) can be used for further diagnostics.
Clear the alarm with the RESET key. Restart the part program.
Axis %1, difference for function safely reduced speed n
%2, drive: %3
%1 = axis name, spindle number
%2 = monitoring status, safely reduced speed n
%3 = monitoring status, safely reduced speed n
In the crosswise data comparison of result list 2 between the NCK and
drive monitoring channels, a difference in the monitoring state of the
safely reduced speed monitoring n
-- Safely reduced speed n
-- Safely reduced speed n
Displayed monitoring status (NCK/drive (%2, %3)):
-- OFF = monitoring inactive in this monitoring channel
-- 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
