2-174

SINUMERIK 802D sl, Diagnostics Manual, 06/2009

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 the setup and optimization data of

the drive actuator in accordance with the Installation and Start-up Guide and make corrections.

Increase the tolerance window in MD35150 $MA_SPIND_DES_VELO_TOL.

Program Con-

tinuation:

Clear alarm with the RESET key in all channels of this mode group. 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: Please inform the authorized personnel/service department. Provide an interlock in the PLC user pro-

gram so that no axis stop can be initiated when tapping is active. If the tapping operation is to be ter-

minated 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: Please inform the authorized personnel/service department. Check the axis-specific/spindle-specific

stop V380x 0004.3 (Spindle stop).

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

Definitions: When DECODING SINGLE BLOCK has been selected and there is a chain of thread blocks, then

machining pauses occur at the block limits until the next block is executed with the new NC Start.

In normal single block mode, the program is stopped by a higher-level logic only at the block bound-

aries at which no contour distortions or contour errors can occur. With chained thread blocks, this is

the last thread block!

Reaction: Alarm display.

Remedy: If only one thread block has been programmed, the alarm message can be ignored.

If there are several consecutive thread blocks, this machining section must not be executed in the

automatic DECODING SINGLE BLOCK mode.

Program Con-

tinuation:

Clear alarm with NC START or RESET key and continue the program.

22270 [Channel %1: ] Block %2 maximum tapping speed reached

Parameters: %1 = Channel number

%2 = Block number, label

%3 = Position

Definitions: The following additional parameters are output in order to ascertain the problem:

1 2 ... 169 170 171 172 173 174 175 176 177 178 179 ... 339 340
