Axis %1 difference in function safe velocity nx, NCK: %2 drive: %3
%1 = Axis number
%2 = Monitoring status safe velocity nx
%3 = Monitoring status safe velocity nx
During cross-comparison of result list 2 a difference was detected between the NCK and
drive monitoring channels in the status of safe velocity monitoring.
• Safe velocity nx+: Bit 16, 17 in result list 2
• Safe velocity nx-: Bit 18, 19 in result list 2
Monitoring status (%2, %3):
• 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.
If a safe monitoring was active, STOP B was also triggered automatically. In this case, a
power OFF/ON of the control will be required.
Check whether the safe actual values in both monitoring channels are the same.
For further diagnostics, the drive machine data 1391, 1392 and the servo trace signals
"Result list 2, NCK" and "Result list 2, drive" can be used.
Clear alarm with the RESET key. Restart part program
Axis %1 difference in function cam modulo monitoring, NCK: %2 drive: %3
%1 = Axis number
%2 = Monitoring status safe cam modulo range
%3 = Monitoring status safe cam modulo range
During cross-comparison of result list 2 a difference was detected between the NCK and
drive monitoring channels in the status of cam modulo monitoring.
Safe cam modulo range: Bit 20, 21 in result list 2
Monitoring status (%2, %3):
• 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.
If a safe monitoring was active, STOP B was also triggered automatically. In this case, a
power OFF/ON of the control will be required.
Check whether the safe actual values in both monitoring channels are the same.
For further diagnostics, the drive machine data 1391, 1392 and the servo trace signals
"Result list 2, NCK" and "Result list 2, drive" can be used.
Clear alarm with the RESET key. Restart part program
Stop A triggered at least in 1 axis
This is only an informational alarm indicating that Stop A has been triggered in at least
one axis and Power On is required for alarm acknowledgment. This alarm occurs if the
alarm priority function was activated in MD $MN_SAFE_ALARM_SUPPRESS_LEVEL.
- Interface signals are set.
- Alarm display.
Trigger a "Pulse suppression" for the affected axis.
Find the error cause by means of further alarm messages.
Switch control OFF - ON.
