Block change
The block change is stopped and the machining blocks are not started until the gear stage has been changed by
the PLC (DB31, ... DBX16.3).
End of gear stage change
Once the gear stage 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 gearspecific limit values (min./max. speed of gear stage, etc.) correspond to the check-back values of the
actual gear stage.
Boundary conditions
• The spindle must have at least one measuring system.
• Positioncontrolled 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 gear stage change at fixed position
is activated by the configuration:
MD35010 $MA_GEAR_STEP_CHANGE_ENABLE = 2
16.4.9
Configurable gear step in M70
Technical background
In some machines the spindle needs to be in a particular gear step during axis mode.
Possible reasons:
• Only one optimization (K
v
, feedforward control, filter) to suit a gear step can be found in the servo parameter
set for axis mode (index 0). The machine data for this parameter set should not be rewritten.
• There is only one mechanical transmission ratio which, unlike the others, possesses little or no backlash
compensation. The spindle can only follow a path motion or transformations (e.g. TRANSMIT) together with
other axes in this gear step.
