NCK alarms

SINUMERIK 802D sl, Diagnostics Manual, 06/2009

Use G63 or G331/G332.

Program Con-

tinuation:

Clear alarm with the RESET key. Restart part program

10610 [Channel %1: ] Axis %2 not stopped

Parameters: %1 = Channel number

%2 = Block number, label

Definitions: An axis/spindle has been positioned over several NC blocks using the POSA/SPOSA instruction. The

programmed target position had not yet been reached ("exact stop fine" window) when the axis/spin-

dle was reprogrammed.

Example:

N100 POSA[U]=100

N125 X... Y... U... ; e.g.: U axis still travels from N100!

Reaction: NC Start disable in this channel.

Interface signals are set.

Alarm display.

NC Stop on alarm.

Remedy: Check and correct the part program (analyze whether motion beyond block boundaries is appropriate

here). Prevent block change by means of the keyword WAITP for axes or WAITS for spindles until the

positioning axes or positioning spindles have also reached their target position.

Example for axes:

N100 POSA[U]=100

N125 WAITP(U)

N130 X... Y... U...

Example for spindles:

N100 SPOSA[2]=77

N125 WAITS(2)

N130 M6

Program Con-

tinuation:

Clear alarm with the RESET key. Restart part program

10620 [Channel %1: ] Block %3 axis %2 at software limit switch %4

Parameters: %1 = Channel number

%2 = Axis name, spindle number

%3 = Block number, label

%4 = String

Definitions: During the traversing motion, the system detected that the software limit switch would be traversed in

the direction indicated. Exceeding the traversing range was not detected during block preparation

because there has either been a motion overlay or a zero offset has been executed or a coordinate

transformation is active.

Reaction: Local alarm reaction.

NC Start disable in this channel.

Interface signals are set.

Alarm display.

NC Stop on alarm at block end.

Remedy: Depending on the reason for this alarm being triggered, the following remedial measures should be

undertaken:

- Handwheel override: Cancel the motion overlay and avoid this or keep it smaller when the program

is repeated.

- Transformation: Check the preset/programmed zero offsets (current frame). If the values are correct,

the tool holder (fixture) must be moved in order to avoid triggering the same alarm when the program

is repeated, which would again cause the program to be aborted.

Program Con-

tinuation:

Clear alarm with the RESET key. Restart part program

10621 [Channel %1: ] Axis %2 rests on software limit switch %3%4

Parameters: %1 = Channel number

%2 = Axis name, spindle number

%3 = String
