SINUMERIK 802D sl, Diagnostics Manual, 06/2009

Remedy: - Check probe

- Check start positioning for measuring

- Check program

Program Con-

tinuation:

Clear alarm with the RESET key. Restart part program

21740 Output value at analog output no. %1 has been limited

Parameters: %1 = No. of output

Definitions: The value range of the analog output n is limited by MD10330

$MN_FASTIO_ANA_OUTPUT_WEIGHT[n].

Reaction: Alarm display.

Remedy: With $A_OUTA[..] = x no greater values can be programmed than permitted in the respective machine

data.

Program Con-

tinuation:

Clear alarm with the Delete key or NC START.

21760 [Channel %1: ] Block %2 too many auxiliary functions programmed

Parameters: %1 = Channel number

%2 = Block number, label

Definitions: The number of programmed auxiliary functions has exceeded the maximum permissible amount. This

alarm can occur in conjunction with motion synchronous actions: The maximum number of auxiliary

functions must not be exceeded in motion block and motion synchronous actions.

Reaction: Interpreter stop

NC Start disable in this channel.

Interface signals are set.

Alarm display.

NC Stop on alarm.

Remedy: Modify part program.

Program Con-

tinuation:

Clear alarm with the RESET key. Restart part program

21800 [Channel %1: ] Workpiece setpoint %2 reached

Parameters: %1 = Channel number

%2 = Workpiece setpoint

Definitions: This alarm is activated via MD27880 $MC_PART_COUNTER, bit 1: The number of counted work-

pieces ($AC_ACTUAL_PARTS or $AC_SPECIAL_PARTS) is equal or already greater than the pro-

grammed value for the number of required workpieces ($AC_REQUIRED_PARTS). At the same time,

the channel VDI signal "Workpiece setpoint reached" is output. The value for the number of counted

workpieces ($AC_ACTUAL_PARTS) is reset, while the value of $AC_SPECIAL_PARTS is retained.

Note:

The setpoint/actual comparisons of the workpieces are only made after an NC start

under the condition that $AC_REQUIRED_PARTS > 0. If $AC_REQUIRED_PARTS

has a negative value, all workpiece counts activated through MD27880 $MC_PART_COUNTER are

frozen at the values they have reached,

and the nominal/actual comparison is discontinued.

Reaction: NC not ready.

Interface signals are set.

Alarm display.

Remedy: No program interrupt. Delete alarm display.

Program Con-

tinuation:

Clear alarm with the Delete key or NC START.

22000 [Channel %1: ] Block %3 spindle %2 gear stage change not possible

Parameters: %1 = Channel number

%2 = Spindle number

%3 = Block number, label

Definitions: A gear stage change for the spindle will not be possible, if:

- thread cutting (G33, G34, G35) is active

- the spindle is active as master or slave spindle in a coupling

- the spindle is being positioned

Reaction: Interpreter stop
