The specified tool is either
from a non-considered magazine,
from a non-considered wear grouping,
or from a non-active wear grouping
in a buffer location (is neither magazine nor wear grouping).
Reaction: Interface signals are set.
Alarm display.
Remedy: The alarm is intended for information purposes. If only one tool in a group can be active at a time for
technological reasons or for reasons of display, the "active" status must be canceled for the tool caus-
ing the error.
Otherwise, the alarm can be ignored or even suppressed via the MD11410
$MN_SUPPRESS_ALARM_MASK.
Typical reasons of display are present, if the operator works with the function 'definite D numbers',
which can be displayed on Siemens MMC in a definite form only, if exactly one tool from a tool group
has the status 'active'.
Before machining can be started or before the SETTA (or corresponding MMC operation, ...) language
command is used, all tools of the magazine should have the status "not active".
One option to achieve this is programming SETTIA (or corresponding MMC operation, ...).
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
22100 [Channel %1: ] Block %3 spindle %2 chuck speed exceeded
Parameters: %1 = Channel number
%2 = Axis name, spindle number
%3 = Block number, label
Definitions: The actual spindle speed is higher than the maximum speed configured in MD35100
$MA_SPIND_VELO_LIMIT plus a tolerance of 10 percent (fixed setting).
The alarm should not occur after correct optimization of the drive actuator and gear configuration.
This alarm can be reconfigured with MD11412 $MN_ALARM_REACTION_CHAN_NOREADY (chan-
nel not ready to operate) to 'BAG not ready'.
Note: Reconfiguring affects all alarms with alarm response 'Chan not ready'.
Reaction: Mode group not ready.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Channel not ready.
Remedy: Please inform the authorized personnel/service department. Check the setup and optimization data of
the drive actuator in accordance with the Installation and Start-up Guide and make corrections.
Increase the tolerance window in MD35150 $MA_SPIND_DES_VELO_TOL.
Program Con- Clear alarm with the RESET key in all channels of this mode group. Restart part program.
tinuation:
22101 [Channel %1: ] Block %3 spindle %2 maximum speed for encoder
resynchronization exceeded
Parameters: %1 = Channel number
%2 = Axis name, spindle number
%3 = Block number, label
Definitions: The maximum encoder speed was exceeded with G33, G95, G96 or G97. Reference to actual speed
and actual position is no longer possible. The NC reduces the setpoint speed with the above functions
until the active encoder is able to measure again. The alarm is issued if the encoder still reports the
fault.
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: - Program speed limit with G26.
- Reduce the maximum speed in the appropriate machine data.
Program Con- Clear alarm with the RESET key. Restart part program
