300914 Safe speed exceeded Reset key
Cyclic in SI monitoring cycle.
The drive is stopped by the response configured in MD 1361. After completion of the stop reaction, the drive re-
mains under control, and the axis is monitored for SBH.
The axis has moved faster than defined in MD 1331, i.e. the axis has exceeded the permissible speed limit.
The user must find the cause and initiate appropriate measures.
Applies as from SW 5.4
300915 Safe end position exceeded Reset key
In monitoring cycle.
The drive is stopped by the response configured in MD 1361. After completion of the stop reaction, the drive re-
mains under control, and the axis is monitored for SBH.
The axis has traveled beyond the end position entered in data MD 1334 and MD 1335.
If no apparent operating error has occurred:
Check the input value of the machine data, check the SGEs: of the 2 end positions, was the correct one selected?
If MDs and SGEs are correct, inspect the machine for damage and repair the damage.
Applies as from SW 5.4
300950 Axis is not safely referenced
In monitoring cycle.
No stop response was initiated. The alarm remains active, when the SN/SE functions are enabled, until the axis
state ”axis safely referenced” is attained.
The standstill position stored before the machine was switched off does not match the actual position (reference
position) detected on power–up.
This alarm requests the user to confirm the present actual position. The position should be established as follows
S Measure the position
S Travel to a known position
If safe automatic referencing is not possible, the user must issue a user authorization for the new position with the
softkey. This user authorization identifies the above position as safe, i.e. the axis state ”axis safely referenced” is
attained.
If the axis has not been referenced safely, and the user authorization is not active:
S The safe cams are active but not yet safe
S The safe end positions are not yet active
Applies as from SW 5.4
300951 Teststop running
In monitoring cycle.
The pulses are deleted.
S If, following the time configured in MD 1357 (time for checking pulse deletion), the positive acknowledgement
of pulse deletion has not been detected, STOP A is triggered.
S If the pulse deletion is acknowledged internally in the drive within the configured time, a stop response is not
initiated. The alarm remains active, on selection via SGE ”test stop selection”, until the selection is canceled.
The test stop has been activated by the user by setting SGE ”test stop selection”. When the user cancels the ”test
stop selection” SGE, the alarm is deactivated.
If STOP A was triggered, it is only possible to restart by POWER ON.
Applies as from SW 5.4
