SINUMERIK 840D sl/840D/840Di/810D Diagnostics Guide (DA), 08/2005 Edition
Remedy: No remedy required
Program Con-
tinuation:
Clear alarm with the RESET key in all channels of this mode group. Restart part program.
4000 Channel %1 machine data %2[%3] has gap in axis assignment
Parameters: %1 = Channel number
%2 = String: MD identifier
Definitions: The assignment of a machine axis to a channel by the machine data 20070
AXCONF_MACHAX_USED must be contiguous. At system power-up (Power On) gaps
are detected and displayed as an alarm.
Reactions: - NC not ready.
- Mode group not ready, also effective for single axes
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: Please inform the authorized personnel/service department. The entries for the indices for
the machine axes used in the channels must be contiguous in table
$MC_AXCONF_MACHAX_USED. Channel axis gaps must be enabled via
$MN_ENABLE_CHAN_AX_GAP.
Program Con-
tinuation:
Switch control OFF - ON.
4001 Channel %1 axis %2 defined for more than one channel via machine data %3
Parameters: %1 = Channel number
%2 = Index: Machine axis number
%3 = String: MD identifier
Definitions: In the channel-specific MD: 20070 AXCONF_MACHAX_USED [CHn, AXm]=x (n ... chan-
nel number, m ... channel axis number, x ... machine axis number), several channels were
assigned to a machine axis without having a master channel defined for this axis.
There is usually not much point in assigning a machine axis to several channels. In
exceptional cases, multiple assignment can be performed if a master channel is defined
for this axis. The channel assignment can be performed in accordance with the machining
requirements in the NC part program by means of a keyword (yet to be defined in later
product versions).
Reactions: - NC not ready.
- Mode group not ready, also effective for single axes
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: Please inform the authorized personnel/service department. In the axis-specific MD
30550 AXCONF_ASSIGN_MASTER_CHAN [AXm]=n (m ... machine axis number, n ...
channel number), a master axis was set for the axes that are supposed to be alternately
assigned by the NC program to one or the other channel.
Program Con-
tinuation:
Switch control OFF - ON.
4002 Channel %1 machine data %2[%3] assigns an axis not defined in channel
Parameters: %1 = Channel number
%2 = String: MD identifier
%3 = Index: MD array
