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 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 reference mode 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:
When setting 34200 ENC_REFP_MODE = 6 the 2nd encoder must first be referenced.
Reaction:
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy:
Modify referencing mode ENC_REFP_MODE or reference 2nd encoder.
Program
Continuation:
Clear alarm with the RESET key. Restart part program
20050
Channel %1 axis %2 handwheel mode active
Parameters:
%1 = Channel number
%2 = Axis name, spindle number
Definitions:
The axes cannot be traversed in JOG mode using the traversing keys because traversing is still taking
place via the handwheel.
Reaction:
Alarm display.
Remedy:
Decide whether the axis is to be traversed by means of the jog keys or via the handwheel. End
handwheel travel and delete the axial distance-to-go if necessary (interface signal DB 31 - 48, DBX
2.2).
Program
Continuation:
Alarm display showing cause of alarm disappears. No further operator action necessary.
20051
Channel %1 axis %2 handwheel mode not possible
Parameters:
%1 = Channel number
%2 = Axis name, spindle number
Definitions:
The axis is already traveling via the traversing keys, so handwheel mode is no longer possible.
Reaction:
Alarm display.
Remedy:
Decide whether the axis is to be traversed by means of the jog keys or via the handwheel.
Program
Continuation:
Alarm display showing cause of alarm disappears. No further operator action necessary.
