SINUMERIK 840D sl/840D/840Di/810D Diagnostics Guide (DA), 08/2005 Edition
Program Con-
tinuation:
Switch control OFF - ON.
4033 Caution: NCU link communication still not connected
Definitions: The NCU link communication could not be established due to other active alarms. This is
the case, for example, if during boot-up the system detects and modifies incorrect cycle
times (see alarm 4110).
Reactions: - NC not ready.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: Analyze and fix the other alarms and start the control again.
Program Con-
tinuation:
Switch control OFF - ON.
4034 Local link axis %1 is not allowed for different interpolation cycle time = %2/%3
Parameters: %1 = Axis name
%2 = Local interpolation cycle
%3 = Max. interpolation cycle
Definitions: Local link axes are only permissible on an NCU if the interpolation cycle set corresponds
to the slowest interpolation cycle of the interconnected NCU systems.
Reactions: - NC not ready.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: Remove local link axis (see MN_AXCONF_MACHAX_NAME_TAB and
MN_AXCT_AXCONF_ASSIGN_TAB1) or adapt the interpolation cycle
(MN_IPO_SYSCLOCK_TIME_RATIO).
Program Con-
tinuation:
Switch control OFF - ON.
4035 Interpolation cycle from NCU%1 = %2 does not match NCU%3 = %4
Parameters: %1 = NCU_number1
%2 = MD value of NCU_number1
%3 = NCU_number2 (with slowest IPO cycle)
%4 = MD value of NCU_number2
Definitions: Occurs only with an NCU link system. The interpolation cycles of the NCUs specified in
the alarm do not match one another. The slowest IPO cycle in interconnected NCU sys-
tems must be an integral multiple of all configured IPO cycles.
Reactions: - NC not ready.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: Set a suitable value in MN_IPO_SYSCLOCK_TIME_RATIO for all interconnected NCUs.
