F1: Travel to fixed stop
6.2 General functionality
The window must be selected by the user such that the alarm is activated only when the axis leaves the fixed
stop position.
Enabling the fixed stop alarms
With the machine data:
MD37050 $MA_FIXED_STOP_ALARM_MASK
enabling the fixed stop alarms can be established as follows:
MD37050 = 0
MD 37050 = 2
MD 37050 = 3
All other permissible values of 7 or less do not suppress any alarms.
Using the parts program command NEWCONF a new setting can be activated.
Fixed stop is not reached
If the programmed end position is reached, without detecting the state "fixed stop reached", then depending on
the state of the machine data:
MD37050 $MA_FIXED_STOP_ALARM_MASK (Release of fixed stop alarms)
the alarm 20091 "Fixed stop not reached" is output.
Function abort
If the "Travel to fixed stop" function is aborted owing to a pulse cancellation command, cancelation of PLC
acknowledgments or a Reset in the approach block, the display or suppression of alarm 20094 can be controlled
via machine data:
MD37050m $MA_FIXED_STOP_ALARM_MASK
can be controlled.
Abort without alarm
The travel to fixed stop can be aborted by the PLC in the approach block without triggering an alarm (for
example, when the operator actuates a key), if in the machine data:
MD37050 $MA_FIXED_STOP_ALARM_MASK
the alarm 20094 is suppressed.
The Travel to fixed stop function is deselected in response to both "Fixed stop not reached" and "Fixed stop
aborted".
