Program Con- Clear alarm with the RESET key in all channels of this mode group. Restart part program.
tinuation:
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 machine data 30200 NUM_ENCS, i.e. the 2nd encoder does not exist.
Reactions: - Alarm display.
Remedy: Please inform the authorized personnel/service department. Enter the number of actual
value encoders used for this axis in the machine data 30200 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 Con- Clear alarm with the Delete key or NC START.
tinuation:
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 (8 parameter sets: 0 ... 7 available).
Reactions: - 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/spin-
dle-specific interface signals (DB 31 - 48, DBX 9.0, 9.1 and 9.2 "Select parameter set
servo A, B, C").
One parameter set includes the following machine data:
• Modify MD 31050: DRIVE_AX_RATIO_DENOM [n]
• Modify MD 31060: DRIVE_AX_RATIO_NUMERA [n]
• Modify MD 32200: POSCTRL_GAIN [n]
• Modify MD 32800: EQUIV_CURRCTRL_TIME [n]
• Modify MD 32810: EQUIV_SPEEDCTRL_TIME [n]
• Modify MD 32910: DYN_MATCH_TIME [n]
• Modify MD 36200: AX_VELO_LIMIT [n]
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
25201
Axis %1 drive fault
Parameters: %1 = Axis name, spindle number
Definitions: The drive signals a serious fault of status class 1 (ZK1). The exact cause of the fault can
be recognized by evaluating the following drive alarms which are output in addition:
Alarm 300 500, alarms 300 502 - 300 505, alarm 300 508, alarm 300 515, alarm 300 608,
alarm 300 612, alarm 300 614, alarms 300 701 - 300 761, alarm 300 799.
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY
(channel not ready).
Reactions: - Mode group not ready.
- The NC switches to follow-up mode.
- Channel not ready.
- NC Start disable in this channel.
