Parameters:
%1 = Axis name, spindle number
%2 = Drive number
Definitions:
The drive is not communicating.
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 the bus configuration.
- Check the interface (connector removed, option module inactive, etc.).
Program
Continuation:
Clear alarm with the RESET key. Restart part program
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The sign-of-life cell is no longer being updated by the drive.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 the cycle settings.
- Increase the cycle time if necessary.
- Power-up the drive again.
- Check drive software.
Program
Continuation:
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-Type-2000.
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:
- $MA_CTRLOUT_TYPE not equal to 0 as a result of an oversight; the drive should actually 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 SDB-Type-2000) or different addresses were selected for the input and output slots
of the drive in the Profibus configuration.
Program
Continuation:
Switch control OFF - ON.
