Axis %1 positioning monitoring
%1 = Axis name, spindle number
The axis of blocks in which "exact stop" is active must have reached the exact
positioning window after the positioning time set in the axis-specific MD 36
020 POSITIONING_TIME.
Exact stop coarse: MD 36 000 STOP_LIMIT_COARSE
Exact stop fine: MD 36 010 STOP_LIMIT_FINE
Response
Channel not ready for operation.
NC Start inhibited.
NC Stop at alarm.
The NC changes to follow-up mode.
Alarm display.
Interface signals are set.
Check whether the exact stop limit (coarse and fine) corresponds to the dy-
namic possibilities of the axes; otherwise, increase the exact stop limit, if nec-
essary, in conjunction with the positioning time defined in MD 36 020
POSITIONING_TIME.
Check speed controller/position controller optimization; select gain as high as
possible.
Check setting of the loop-gain factor (K
V
factor) (MD 32 200
POSCTRL_GAIN); increase if necessary.
Press the RESET key to clear the alarm. Restart part program.
Axis %1 drive fault
%1 = Axis name, spindle number
For step-switching motor axes only:
The rotation monitoring error occurred. The step-switching motor lost steps
due to overload.
Mode group ('BAG') not ready for operation.
Channel not ready for operation.
NC Start inhibited.
NC Stop at alarm.
Alarm display.
Interface signals are set.
Reference point lost.
Check application (accelerations, speeds)
Press the RESET key to clear the alarm; approach reference point.
Axis %1 clamping monitoring
%1 = Axis name, spindle number
The clamped axis has been pressed from its position. The permissible deviation
is defined in the axis-specific MD 36 050 CLAMP_POS_TOL.
Axis clamping is activated by the axis-specific interface signal
V 380x0002.3: "Clamping running".
