SINUMERIK 840D/840Di/810D Diagnostics Guide (DA), 10.04 Edition
Drive %1 removed for diagnostics
%1 = Drive number
The alarm indicates that the drive bus configuration has been changed temporarily. The
alarm is output if MD 13030 $MN_DRIVE_MODULE_TYPE has value 0 (zero) when a
drive is configured.
- Mode group not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Normal operation (full bus configuration): Integrate drive module into the bus again, enter
the correct type in MD 13030 $MN_DRIVE_MODULE_TYPE.
• Normal operation (module remains removed): Remove the module in the configuration
screen. Remove all connections to outputs and inputs.
• MD30110 $MA_CTRLOUT_MODULE_NR
• MD30130 $MA_CTRLOUT_TYPE
• MD30220 $MA_ENC_MODULE_NR
• MD30240 $MA_ENC_TYPE
• MD11342 $MA_ENC_HANDWHEEL_MODULE_NR
Switch control OFF - ON.
Drive power failure
In one or several (all) drive modules, there is a power failure although power was previ-
ously available. (The timeout is checked for write/read accesses. Timeouts are interpreted
as power failure because this is the most probable case. The test takes place in the cyclic
mode only but not at system power-up.)
Since the drives in the SINUMERIK 840D and the NC-CPU have the same power supply,
this error does not occur here because then the NCU is also without power supply. In the
SINUMERIK FM-NC, this error can arise because the power supply is separate.
- NC not ready.
- The NC switches to follow-up mode.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Switch off the power to the system and switch on again - the drives start up again.
Clear alarm with the RESET key in all channels. Restart part program.
Bus communications failure
This alarm indicates that there is still no power supply to the drives although the NC is
already running. This message comes only if no drive module has been signaled. (In the-
ory, it could also be a bus error interrupting the connection to the 1st module).
- NC not ready.
- The NC switches to follow-up mode.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
