26102 Axis %1 drive %2 sign of life missing
Parameters: %1 = axis name, spindle number
%2 = drive number
Definitions: The sign of life cell is no longer being updated by the drive.
Reaction: Mode group not ready.
The NC switches to follow-up mode.
Channel not ready.
NC Start disable in this channel.
Axes of this channel must be re-referenced.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Check cycle setting, extend cycle time if required.
Restart drive, check drive software
Program Con-
tinuation:
Clear alarm with the RESET key. Restart part program
26105 Drive of axis %1 not found
Parameters: %1 = axis name, spindle 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 SDB.
Reaction: 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:
MD 30130 CTRLOUT_TYPE not equal to 0 as a result of an oversight; the drive should actually be
simulated (= 0).
MD 30110 CTRLOUT_MODULE_NR entered incorrectly, i.e. the logical drive numbers have been
mixed up, or a drive number which does not exist on the bus has been entered (check e.g. the number
of slaves)
An incorrect SDB is being used or the addresses of the input and output slots of the drives were not
selected during PROFIBUS configuration.
Program Con-
tinuation:
Switch control OFF - ON.
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 SDB.
Reaction: 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:
MD 30240 ENC_TYPE not equal to 0 as a result of an oversight; the encoder should actually be sim-
ulated (= 0).
MD 30220 ENC_MODULE_NR entered incorrectly, i.e. the logical drive numbers have been mixed
up, or a drive number which does not exist on the bus has been entered (check e.g. the number of
slaves)
An incorrect SDB is being used or the addresses of the input and output slots of the drives were not
selected during PROFIBUS configuration.
Program Con-
tinuation:
Switch control OFF - ON.
