Reactions: - 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 34040 REFP_VELO_SEARCH_MARKER and/or increase the MD for
the velocity tolerance 35150 SPIND_DES_VELO_TOL.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:

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!
Reactions: - 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 Con- Clear alarm with the RESET key. Restart part program
tinuation:
20008
Channel %1 axis %2 reference point approach requires second referenced measur-
ing 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.
Reactions: - 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 Con- Clear alarm with the RESET key. Restart part program
tinuation:
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.
Reactions: - 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 Con- Alarm display showing cause of alarm disappears. No further operator action necessary.
tinuation:
20051
Channel %1 axis %2 handwheel mode not possible
Parameters: %1 = Channel number
%2 = Axis name, spindle number
