- Mode group not ready.
- Channel not ready.
- NC Start disable in this channel.
- NC Stop on alarm.
- The NC switches to follow-up mode.
- Alarm display.
- Interface signals are set.
Possible causes:
• $MA_CTRLOUT_TYPE not equal to 0 as a result of an oversight; the drive should actu-
ally be simulated (= 0).
• $MA_CTRLOUT_MODULE_NR entered incorrectly, i.e. the logical drive numbers were
exchanged and an invalid value is stored for this drive in
$MN_DRIVE_LOGIC_ADDRESS (see 3.) or a drive number which does not exist on
the bus was entered (check the number for slaves, for example).
• $MN_DRIVE_LOGIC_ADDRESS contains values which were not configured on the
Profibus (i.e. the values are not in SDB1000) or different addresses were selected for
the input and output slots of the drive in the Profibus configuration.
Switch control OFF - ON.
Encoder %2 of axis %1 not found
%1 = Axis name, spindle number
%2 = Encoder number
The drive configured for the specified axis could not be found. For example, a Profibus
slave was configured on the NC but is not contained in SDB1000.
- Mode group not ready.
- Channel not ready.
- NC Start disable in this channel.
- NC Stop on alarm.
- The NC switches to follow-up mode.
- Alarm display.
- Interface signals are set.

• $MA_ENC_MODULE_NR entered incorrectly, i.e. the logical drive numbers were

Switch control OFF - ON.
Independent drive stop/retract triggered
Informational alarm: An "independent extended stop or retract" was triggered on the drive
bus for at least one axis. The drive in question subsequently ignores NC travel com-
mands. The bus must be rebooted (hardware reset).
- NC not ready.
- NC Start disable in this channel.
- NC Stop on alarm.
- The NC switches to follow-up mode.
- Alarm display.
- Interface signals are set.
