Parameters: %1 = Channel number
%2 = Block number, label
Definitions: A preset command was given from MMC or PLC while an axis was traveling in JOG
mode.
Reactions: - Interface signals are set.
- Alarm display.
Remedy: Wait until the axis is stationary.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
22322
Channel %1 axis %2 PRESET: illegal value
Parameters: %1 = Channel number
%2 = Axis name, spindle number
Definitions: The entered Preset value is too large (number format overflow).
Reactions: - NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: Use more realistic (smaller) Preset values.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
25000
Axis %1 hardware fault of active encoder
Parameters: %1 = Axis name, spindle number
Definitions: The signals of the currently active position actual value encoder (interface signal DB 31 -
48, DBX 1.5 = 1 or DBX 1.6 = 1) are missing, do not have the same phase, or exhibit
grounding/short-circuit.
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY
(channel not ready).
Reactions: - Mode group not ready.
- The NC switches to follow-up mode.
- Channel not ready.
- NC Start disable in this channel.
- Axes of this channel must be re-referenced.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
- Channel not ready.
Remedy: Please inform the authorized personnel/service department. Check measuring circuit con-
nectors for correct contacting. Check encoder signals and replace the encoder if faults
are found.
Program Con- Switch control OFF - ON.
tinuation:
25001
Axis %1 hardware fault of passive encoder
Parameters: %1 = Axis name, spindle number
Definitions: The signals from the position actual value encoder that is presently not active are missing,
or they are not of the same phase, or they exhibit grounding/short-circuit.
Reactions: - Alarm display.
Remedy: Please inform the authorized personnel/service department. Check measuring circuit con-
nectors for correct contacting. Check encoder signals and replace the encoder if faults
