SINUMERIK 802D sl, Diagnostics Manual, 06/2009

Program Con-

tinuation:

Clear alarm with the RESET key in all channels of this mode group. Restart part program.

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 Con-

tinuation:

Clear alarm with the RESET key in all channels of this mode group. Restart part program.

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 encod-

ers 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 Con-

tinuation:

Clear alarm with the Delete key or NC START.

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).

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 <Regler-Parametersatz1A-C/> (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 Con-

tinuation:

Clear alarm with the RESET key. Restart part program
