End of gear step change
Once the gear step change has been completed, the spindle returns to open-loop control
mode and will automatically change to the controller mode defined by SPCON or SPCOF.
All gear-specific limit values (min./max. speed of gear step, etc.) correspond to the check-
back values of the actual gear step.
Supplementary conditions
• The spindle must have at least one measuring system.
• Position-controlled operation must be possible and must have been activated.
• Generally, it must be possible to execute SPOS from the part program, from a
synchronized action or via FC18: “Start spindle positioning” without errors.
Unless all requirements can be met, the function described cannot be used successfully.
Activation
The function of the gear step change at fixed position
is activated by setting:
MD35010 $MA_GEAR_STEP_CHANGE_ENABLE = 2.

Application
The "Selectable spindles" function allows you to write part programs with reference to the
spindles used ("Channel spindle, Logical spindle") regardless of the actual assignment of
configured spindles ("Physical spindles") to a channel.
The physical spindles loaded or unloaded by "axis replacement" no longer have to be
specified explicitly in the part program.
