Overview of Alarms
Reactions: - Mode group 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.
Remedy: 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.
Program Con- Switch control OFF - ON.
tinuation:
26106
Encoder %2 of axis %1 not found
Parameters: %1 = Axis name, spindle number
%2 = Encoder number
Definitions: 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.
Reactions: - Mode group 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.
Remedy: Possible causes:
• $MA_ENC_TYPE not equal to 0 as a result of an oversight; the encoder should actually
be simulated (= 0).
• $MA_ENC_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 next paragraph) 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.
Program Con- Switch control OFF - ON.
tinuation:
26110
Independent drive stop/retract triggered
Definitions: 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).
Reactions: - NC not ready.
- The NC switches to follow-up mode.
- NC Start disable in this channel.
