Remedy: Please inform the authorized personnel/service department.

The spindle number is stored in the axis-specific MD35000 $MA_SPIND_ASSIGN_TO_MACHAX.

The channel to which this machine axis/spindle is assigned is listed in the machine axis index. (The

machine axis number is given in the channel-specific MD20070 $MC_AXCONF_MACHAX_USED).

Program Con-

tinuation:

Switch control OFF - ON.

4225 [Channel %1: ] Axis %2 declaration as rotary axis missing

Parameters: %1 = Channel number

%2 = Axis name, axis number

Definitions: The modulo functionality requires a rotary axis (positions in [deg]).

Reaction: Mode group not ready.

4230 [Channel %1: ] Data alteration from external not possible in current

channel state

Parameters: %1 = Channel number

Definitions: It is not allowed to enter this data while the part program is being executed (e.g. setting data for work-

ing area limitation or for dry run feedrate).

Reaction: Alarm display.

Remedy: The data to be entered must be altered before starting the part program.

Program Con-

4240 Runtime overflow for IPO cycle or position controller cycle, IP %1

Parameters: %1 = Program location

Definitions: The settings for the interpolation and position control cycle were modified before the last power-up

such that too little computing time is now available for the requisite cyclic task.

The alarm occurs immediately after power-up if too little runtime is available even when the axes are

stationary and the NC program has not started. However, task overflow can occur only when compu-

tation-intensive NC functions are called during program execution.

Reaction: NC not ready.

The NC switches to follow-up mode.

Mode group not ready, also effective for single axes

NC Start disable in this channel.
