Axis %1, difference in cam modulo monitoring
%2, drive: %3
%1 = axis name, spindle number
%2 = monitoring status, safe cam modulo range
%3 = monitoring status, safe cam modulo range
In the crosswise data comparison of result list 2 between the NCK and
drive monitoring channels, a difference was detected in the monitoring
status of the cam modulo range monitoring. Safe cam modulo range:
Bits 20, 21 in result list 2
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
violated
Alarm display
NC start disable in this channel
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).
For further diagnostics refer to the drive parameters r9711[0], r9711[1]
and the servo--trace signals "result list 2 NCK" and "result list 2 drive".
Clear the alarm with the RESET key. Restart the part program.
Axis %1 data transfer error, index %2
%1 = axis name, spindle number
%2 = index in the crosswise data comparison
Communication errors between the NCK and drive have meant that for
three times in a row, the crosswise data comparison of the data with
the specified index was not able to be carried out.
Alarm display
In addition, a STOP F is initiated, that can result in the subsequent
Alarm 27001 with fault IDs 0, 27023 and 27024. Alarm 27001 with fault
ID 0 can be prevented using the alarm reduction (MD10094
$MA_SAFE_ALARM_SUPPRESS_LEVEL greater than or equal to 1).
Check the connections between the NCK and drive
Check the configuring of the PROFIBUS telegram (e.g. SI slot
configured).
Check the assignment between the NCK SI axis and SI slot (MD36906
$MA_SAFE_CTRLOUT_MODULE_NR, MD10393
$MN_SAFE_DRIVE_LOGIC_ADDRESS).
Check the assignment of the telegram configuration for the slave OM.
Check and ensure that the EMC conditions are complied with.
