Channel parameters

Further entries which are made in the channel parameters [1] are required for pro-gramming spindles in the part program.

In this case, each spindle to be addressed by this channel must be declared. For this purpose, a string (axis name) and the corresponding logical axis number are defined for each spindle. The axis names of the spindle can be freely selected but they must always start with “S“ (e.g. S, S_MAIN, S1, SPINDEL_1).

In addition, the synchronization modes must be defined spindle-specifically for the spindle M-functions (M3, M4, M5 and M19) and for the S-word. For that, the appropriate meaning of M3, M4, M5 and M19 must be switched [1]-35.

Channel parameters 1:

The synchronization method of the S function has no effect if a spindle M function has been programmed in the NC block. Synchronization only takes place in accordance with the settings for the spindle M function. The following priorities apply:
M19 > M3/M4/M5 > S

If the spindles are to be allowed for in simulation mode “production time calculation”, the data required for this can also be preassigned spindle-specifically.

To remain compatible with standard programming, a spindle must be declared as a so-called main spindle [1]-17/-18. This main spindle can then be programmed together with specific standard functionalities (e.g. tapping and gear changing etc.) in the conventional DIN syntax. Even if there is only one spindle in the system, it must be configured as the main spindle.

Setting a flag allows the optional gear changing function to also be enabled for the main spindle [1]-19.

The configuration defined in the channel parameters [1] is the default assignment available after boot-up of the control system.

Example 1: Configuration of a single-channel system with three spindles. The spindle with axis number 6 is to be the main spindle. Gear changing of this spindle is deactivated.
