Ncu Link Communication Still Not Connected - Siemens Sinumerik 840D sl Diagnostic Manual

03/2009
4033 NOTICE! 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).
Reaction: 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- Switch control OFF - ON.
tinuation:
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.
Reaction: 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 MD10000 $MN_AXCONF_MACHAX_NAME_TAB and
MD12701$MN_AXCT_AXCONF_ASSIGN_TAB1) or adapt the interpolation cycle (MD10070
$MN_IPO_SYSCLOCK_TIME_RATIO ).
Program Con- Switch control OFF - ON.
tinuation:
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 systems must be an integral
multiple of all configured IPO cycles.
Reaction: 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 MD10070 $MN_IPO_SYSCLOCK_TIME_RATIO for all interconnected NCUs.
Program Con- Switch control OFF - ON.
tinuation:
4036 Wrong NCU link configuration by MD %1
Parameters: %1 = String: MD identifier
Definitions: Occurs only with an NCU link system. Different interpolation and position control cycles have been set
in the NCUs of the LINK group. This is only allowed if the function FAST-IPO-LINK in MD18780
$MN_MM_NCU_LINK_MASK has been activated.
Caution: For diagnostic purposes, two additional alarm parameters are output together with this alarm.
- 1. 2nd parameter: Position control or IPO cycle time of this NCU
- 2. 2nd parameter: Position control or IPO cycle time of another NCU.
