Program Con-
tinuation:
Clear alarm with the RESET key. Restart part program
20000 Channel %1 axis %2 reference cam not reached
Parameters: %1 = channel number
%2 = axis name, spindle number
Definitions: After starting the reference point approach, the rising edge of the reduction cam must be reached
within the section defined in the MD 34 030 REFP_MAX_CAM_DIST (phase 1 of referencing). (This
error occurs only with incremental encoders).
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Please inform the authorized personnel/service department.
There are 3 possible causes of error:
1.The value entered in MD 34 030 REFP_MAX_CAM_DIST is too small.
Calculate the maximum possible distance from the start of referencing to the reduction cam and com-
pare with the setting in MD 34 030 REFP_MAX_ CAM_DIST, increase the MD if necessary.
2.The cam signal is not received by the PLC input module.
Actuate the reference point switch manually and check the input signal at the NC/PLC interface (sec-
tion: Switch! Connector! Cable! PLC input! User program).
3.The reference point switch is not operated by the cam.
Check the vertical distance between reduction cam and activating switch.
Program Con-
tinuation:
Clear alarm with the RESET key. Restart part program
20001 Channel %1 axis %2 no cam signal present
Parameters: %1 = channel number
%2 = axis name, spindle number
Definitions: At the beginning of phase 2 of reference point approach, the signal from the reduction cam is no longer
available.
Phase 2 of reference point approach begins when the axis remains stationary after deceleration to the
reduction cam. The axis then starts in the opposite direction in order to select the next zero marker of
the measuring system on leaving the reduction cam or approaching it again (negative/positive edge).
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Check whether the deceleration path after the approach velocity is greater than the distance to refer-
ence point cam - in which case the axis cannot stop until it is beyond the cam. Use a longer cam.
When the axis has stopped on the cam, a check must be made to see whether the signal ”DECELER-
ATION REFERENCE POINT APPROACH" (V 380x1000.7) is still present at the interface to the NC.
Hardware: Wire break? Short circuit?
Software: User program?
Program Con-
tinuation:
Clear alarm with the RESET key. Restart part program
20002 Channel %1 axis %2 zero mark not found
Parameters: %1 = channel number
%2 = axis name, spindle number
Definitions: The zero mark of the incremental encoder is not within a defined section.
Phase 2 of reference point approach ends when the zero mark of the encoder has been detected after
the rising/falling edge of the PLC interface signal "DECELERATION REFERENCE POINT
APPROACH" (V 380x1000.7) has given the trigger start. The maximum distance between the trigger
start and the zero mark that follows is defined in MD 34 060 REFP_MAX_MARKER_DIST.
The monitor prevents a zero mark signal from being overtraveled and the next being evaluated as ref-
erence point signal! (Faulty cam adjustment or excessive delay by the PLC user program).
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
