Overview of alarms
06/2007
NCK alarms/ISO alarms
Remedy:
Check reason for abort:
Servo enable missing (V 380x0001.1)
Traversing key signal + or - missing (V 380x0004.6 and .7)
Feed override = 0
The axis-specific MD 34 110 REFP_CYCLE_NR determines which axes are involved in the channelspecific referencing.
-1:No channel-specific referencing, NC Start without referencing.
0:No channel-specific referencing, NC Start with referencing.
1-8:Channel-specific referencing. The number entered here corresponds to the referencing sequence
(when all axes with contents 1 have reached the reference point, then the axes with contents 2 start,
etc.).
Program Continuation:
Clear alarm with the RESET key. Restart part program
20006
Channel %1 axis %2 reference point creep velocity not reached
Parameters:
%1 = channel number
%2 = axis name, spindle number
Definitions:
In phase 2 of reference point approach (wait for zero mark), the cam end was reached but the reference point approach velocity was not within the tolerance window. (This can occur when the axis is
already at the end of the cam at the beginning of reference point approach. This means that phase 1
has already been concluded and will not be started.)
Phase 2 has been interrupted (this time before the cam) and the reference point approach will be
started once again automatically with phase 1. If the approach velocity is not attained at the second
attempt either, the referencing will be aborted with the alarm display.
Approach velocity: MD 34 040 REFP_VELO_SEARCH_MARKER
Velocity tolerance:MD 35 150 SPIND_DES_VELO_TOL
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.
Reduce the MD for the approach velocity MD 34040 REFP_VELO_SEARCH_MARKER and/or
increase the MD for the velocity tolerance MD 35 150 SPIND_DES_VELO_TOL.
Program Continuation:
Clear alarm with the RESET key. Restart part program
20007
Channel %1 axis %2 reference point approach requires 2 measuring
systems
Parameters:
%1 = channel number
%2 = axis name, spindle number
Definitions:
2 encoders are needed for setting MD 34200 ENC_REFP_MODE = 6!
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.
Modify referencing mode MD 34200 ENC_REFP_MODE or install and configure a second encoder
Program Continuation:
Clear alarm with the RESET key. Restart part program
20008
Channel %1 axis %2 reference point approach requires second
referenced measuring system
Parameters:
%1 = channel number
%2 = axis name, spindle number
Definitions:
The setting MD 34200 ENC_REFP_MODE = 6 does not apply to this control system.
Reaction:
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy:
Change referencing mode MD 34200 ENC_REFP_MODE
