Axis %1, Difference with Cam Modulo Monitoring function, NCK:
%2, drive: %3
Parameter %1 = Axis number
%2 = Monitoring status, safe cam modulo range
%3 = Monitoring status, safe cam modulo range
Explanation In the crosswise data comparison of result list 2 between the monitoring
channel, NCK and drive, a difference was detected in the monitoring state of
the cam modulo area monitoring.
Safe cam modulo range: Bits 20, 21 in result list 2
Monitoring state (%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
Response Alarm display
If safe monitoring was active, then STOP B was also automatically initiated. It is
then necessary to power-down the control and power it up again (power on).
Remedy Check that the safe actual values in both monitoring channels match.
For further diagnostics, the drive machine data 1393, 1394 and the servo trace
signals "Result list 2, NCK" and "Result list 2, drive" can be used.
Program continuation Clear the alarm with the RESET key. Restart part program.
27124
Stop A initiated for at least 1 axis
Explanation This alarm only indicates that Stop A has been triggered in at least one axis
and power on is required to acknowledge the alarm. This alarm is output if the
alarm priority function was activated in MD
$MN_SAFE_ALARM_SUPPRESS_LEVEL.
Response Alarm display
Interface signals are set
"Pulse cancellation" is initiated for the axis involved.
Remedy Locate the cause of the error using additional alarm messages.
Program continuation Power-down the control and power-up again.
27200
PROFIsafe: Cycle time %1 [ms] is too long
Parameter %1 = parameterized cycle time
Explanation The PROFIsafe communication cycle time resulting from MD
$MN_PROFISAFE_IPO_TIME_RATIO and MD $MN_IPO_CYCLE_TIME
exceeds the permissible limit value (25 ms).
Response Mode group not ready
Channel not ready
NC start inhibit in this channel
Interface signals are set
Alarm display
NC stop for alarm
Remedy Correct the cycle time using MD $MN_PROFISAFE_IPO_TIME_RATIO or
reduce the IPO clock cycle.
Program continuation Power-down the control and power-up again.
