Siemens 810T manual Axis, Function of the modes with ªaxis synchronizationº

01.93 3 Operating Sequences

3.1.8 Axis synchronization

3.1.8Axis

The ªaxis synchronizationº function is an ordering data

option.

The ªaxis synchronizationº function duplicates the programmable main axis as long as the maximum permissible number of axes is not exceeded (for 810T/M and 820T/M, five axes). With this function two identical workpieces can be produced by one machine tool with two tool systems by a part program running in a channel of the NC.

The ªaxis synchronizationº function is only available in ªAUTOMATICº and ªMDI AUTOMA- TICº modes and in ªAUTOMATIC interruptedº. For axis synchronization a measuring circuit is available for every axes including the following axis. Therefore, two pairs of axes can be synchronized. The fifth axis remains for use as an independent axis.

The ªaxis synchronizationº function is modal, i.e. it remains active, until a RESET is performed using the RESET key or until a mode change with an implicit RESET is initiated (for further details see Section 2.3.4 ªRESET with change of operating modeº).

Example:

If the part program is interrupted in ªAUTOMATIC modeº, an axis pair can still be traversed

simultaneously after a change to ªJOGº or ªINCºleading( and following axis).

Reason: This mode change does not cause a ªRESETº. The ªaxis synchronizationº function remains active.

3.1.8.1 Function of the modes with ªaxis synchronizationº

ªPRESETº AND ªREFPOINTº modes:

The axes of tool system 1 and tool system 2 must be selected separately using the traverse keys as in the modes without ªaxis synchronizationº.

ªJOGº, ªREPOSº, ªINCº without ªAUTOMATIC interruptedº or ªBlock searchº:

The axes of the two tool systems can only be moved separately.

ªJOGº, ªREPOSº, ªINCº after ªAUTOMATIC interruptedº or ªBlock searchº:

In these modes the offsets which have arisen between the leading and the following axis after ªBlock searchº or ªAUTOMATIC interruptedº etc. can be eliminated in various ways:
