25105 Axis %1 measuring systems differ considerably
Parameters: %1 = Axis name, spindle number
Definitions: The two measuring systems differ considerably, i.e. the cyclically monitored actual value difference between the two
measuring systems is greater than the associated tolerance value set in the machine data MD36510
$MA_ENC_DIFF_TOL. This can only occur when both measuring systems are active (MD30200 $MA_NUM_ENCS
= 2) and referenced. The alarm can be reprogrammed in the MD11412
$MN_ALARM_REACTION_CHAN_NOREADY (channel not ready).
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.
Channel not ready.
Remedy: Please inform the authorized personnel/service department. Check machine data for the active, selected encoders.
Check the machine data relating to encoder (MD36510 $MA_ENC_DIFF_TOL) tolerance.
Program Restart part program.Clear alarm with the RESET key in all channels of this mode group. Restart part program.
Continuation:
25110 Axis %1 selected encoder not available
Parameters: %1 = Axis name, spindle number
Definitions: The selected encoder does not correspond to the maximum number of encoders in the axis-specific MD30200
$MA_NUM_ENCS, i.e. the 2nd encoder does not exist.
Reaction: Alarm display.
Remedy: Please inform the authorized personnel/service department. Enter the number of actual value encoders used for this
axis in the MD30200 $MA_NUM_ENCS ("Number of encoders").
Input value 0: Axis without encoder -> e.g. spindle
Input value 1: Axis with encoder -> default setting
Input value 2: Axis with 2 encoders -> e.g. direct and indirect measuring system
Program Clear alarm with the Delete key or NC START.
Continuation:
25200 Axis %1 requested set of parameters invalid
Parameters: %1 = Axis name, spindle number
Definitions: A new parameter set has been requested for the positioning control. The number of this parameter set is beyond the
permissible limit.
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Please inform the authorized personnel/service department. Check the axis-specific/spindle-specific interface signals
DB380x DBX9.0 - .2 (Select parameter set servo A, B, C).
One parameter set includes the following machine data:
- MD31050 $MA_DRIVE_AX_RATIO_DENOM [n]
- MD31060 $MA_DRIVE_AX_RATIO_NUMERA [n]
- MD32200 $MA_POSCTRL_GAIN [n]
- MD32800 $MA_EQUIV_CURRCTRL_TIME [n]
- MD32810 $MA_EQUIV_SPEEDCTRL_TIME [n]
- MD32910 $MA_DYN_MATCH_TIME [n]
- MD36200 $MA_AX_VELO_LIMIT [n]
Program Clear alarm with the RESET key. Restart part program
Continuation:
25201 Axis %1 drive fault
Parameters: %1 = Axis name, spindle number
