SINUMERIK 802D sl, Diagnostics Manual, 06/2007Edition

Remedy: Check whether the encoder is activated by interface signal: position measuring system V380x0001.5,

or whether the limit frequency for this encoder is correctly preset in MD 36300 ENC_FREQ_LIMIT[0].

Check the maximum spindle speed setting in axis-specific MD 35130

GEAR_STEP_MAX_VELO_LIMIT and reduce if necessary.

Set an upper spindle speed limitation (which must be lower than the maximum encoder limit fre-

quency) with G26 S... in the preceding NC block.

Program Con-

tinuation:

Clear alarm with the RESET key. Restart part program

22150 Channel %1 block %3 spindle %2 maximum speed for position control

exceeded

Parameters: %1 = Channel number

%2 = Axis name, spindle number

%3 = Block number, label

Definitions: The maximum encoder speed was exceeded with SPCON. Position control 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.

Reaction: 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.

Program Con-

tinuation:

Clear alarm with the RESET key. Restart part program

22200 Channel %1 spindle %2 axis stopped during tapping

Parameters: %1 = channel number

%2 = axis name, spindle number

Definitions: When tapping with compensating chuck (G63) the drilling axis was stopped via the NC/PLC interface

and the spindle continues to rotate. The thread and possibly also the tap were damaged as a result.

Reaction: NC Start disable in this channel.

Interface signals are set.

Alarm display.

Remedy: Provide an interlock in the PLC user program so that no axis stop can be initiated when tapping is

active. If the tapping operation must be terminated under critical machine conditions, the spindle and

the axis should be stopped simultaneously if at all possible. Slight differences are then accommodated

by the compensating chuck.

Program Con-

tinuation:

Clear alarm with the RESET key. Restart part program

22250 Channel %1 spindle %2 axis stopped during thread cutting

Parameters: %1 = channel number

%2 = axis name, spindle number

Definitions: The thread cutting axis has been stopped while a thread block was active.

The stop can be caused by VDI signals that cause the feed to be interrupted.

Reaction: NC Start disable in this channel.

Interface signals are set.

Alarm display.

Remedy: Check the axis-/spindle-specific stop signals (V 380x0004.3)

Program Con-

tinuation:

Clear alarm with the RESET key. Restart part program

22260 Channel %1 spindle %2 thread might be damaged

Parameters: %1 = channel number

%2 = axis name

%3 = block number
