NCK alarms/ISO alarms

06/2007 Overview of alarms

2-247

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

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

after 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 velocity of thread axis at position %3

reached

Parameters: %1 = channel number

%2 = block number, label

%3 = axis name, spindle number

Definitions: The spindle speed is so high for a thread cutting operation with G33 that the maximum axis velocity

has been exceeded as a result of the programmed lead.

Reaction: Alarm display.

Remedy: Program a lower spindle speed or a speed limitation with G26 S ... or reduce the spindle speed prior

to the thread block using SD 43 220 SPIND_MAX_VELO_G26 or the spindle override function.

Program Con-

tinuation:

Clear alarm with the Delete key or NC START.

22275 Channel %1 block %2 zero velocity of thread axis at position %3 reached

Parameters: %1 = channel number.

%2 = block number, label.

%3 = position.

Definitions: An axis standstill was reached at the specified position during thread cutting with G35 due to the linear

decrease in the thread lead.

The standstill position of the thread axis is dependent on:

- Programmed thread lead decrease.

- Thread length.

Reaction: Alarm display.

Remedy: Change at least one of the above factors.

Program Con-

tinuation:

Clear alarm with the Delete key or NC START.

22280 Channel %1 in block %2: Prog. acceleration path too short %3, %4

required

Parameters: %1 = channel number

%2 = block number, label

%3 = prog. acceleration path

%4 = required acceleration path

Definitions: In order to stay within the programmed acceleration path, the acceleration caused an overload on the

thread axis. In order to accelerate the axis with the programmed dynamic response, the length of the

acceleration path must be at least as large as the value in parameter %4.

Reaction: Alarm display.

Remedy: Adjust the setting in SD 42010 THREAD_RAMP_DISP.

Program Con-

tinuation:

Clear alarm with the Delete key or NC START.

22290 Channel %1 spindle operation for transformed spindle/axis %2 not

possible (reason: error code %3).

Parameters: %1 = Channel number

%2 = Axis name, spindle number

%3 = Error code
