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 machine data
35100 $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 con-
figuration.
This alarm can be reconfigured with MD 11412
$MN_ALARM_REACTION_CHAN_NOREADY (channel not ready to operate) to 'BAG
not ready'.
Note: Reconfiguring affects all alarms with alarm response 'Chan not ready'.
Reactions: - 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 optimi-
zation data of the drive actuator in accordance with the Installation and Start-up Guide
and make corrections.
Increase the tolerance window in machine data 35150 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.
Reactions: - 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.
