SINUMERIK 802D sl, Diagnostics Manual, 06/2009

NC Start disable in this channel.

Interface signals are set.

Alarm display.

Remedy: The gear stage is to be set prior to the corresponding machining step.

If it is necessary, however, to change the gear stage within one of the above mentioned functions, this

function must be switched off for the time of the gear stage change. Thread cutting is deselected with

G1; synchronous spindle coupling is switched off with COUPOF; the spindle positioning operation is

exited with M3, M4 or M5.

Program Con-

tinuation:

Clear alarm with the RESET key. Restart part program

22010 [Channel %1: ] Block %3 spindle %2 actual gear stage differs from

requested gear stage

Parameters: %1 = Channel number

%2 = Spindle number

%3 = Block number, label

Definitions: The requested gear stage change has been concluded. The actual gear stage reported by the PLC

as being engaged is not the same as the required gear stage called for by the NC. Note: Wherever

possible, the requested gear stage should always be engaged.

Reaction: Alarm display.

Remedy: Please inform the authorized personnel/service department. Correct the PLC program.

Program Con-

tinuation:

Clear alarm with the Delete key or NC START.

22011 [Channel %1: ] Block %3 spindle %2 change to programmed gear stage

not possible

Parameters: %1 = Channel number

%2 = Spindle number

%3 = Block number, label

Definitions: With the 'DryRun', 'ProgramTest' and 'SearchRunByProgTest' functions deselected, it is not possible

in the Repos module to carry out a gear stage change to a previously programmed gear stage. This

is the case, if the spindle is in the deselection block not active in speed control mode, as a slave axis

or in a transformation. Execution of a gear stage change is avoided if the above mentioned functions

are deselected by resetting bit 2 of MD35035 $MA_SPIND_FUNCTION_MASK.

Reaction: Alarm display.

Remedy: Change deselection block or block search target block to speed control mode (M3, M4, M5, SBCOF).

Set bit 2 of MD35035 $MA_SPIND_FUNCTION_MASK to 0.

Program Con-

tinuation:

Clear alarm with the Delete key or NC START.

22020 [Channel %1: ] Block %3 spindle %2 gear step change position not

reached

Parameters: %1 = Channel number

%2 = Spindle number

%3 = Block number, label

Definitions: Through the configuration of MD35010 $MA_GEAR_STEP_CHANGE_ENABLE[AXn] = 2, the spindle

is traversed to the position stored in MD35012 $MA_GEAR_STEP_CHANGE_POSITION[AXn]

before the actual gear step change. The required gear step change position has not been reached.

Reaction: Channel not ready.

NC Start disable in this channel.

Interface signals are set.

Alarm display.

NC Stop on alarm.

Remedy: Correct sequence in the PLC.

Program Con-

tinuation:

Clear alarm with the RESET key. Restart part program
