New: Advanced settings for individual axes
MP_advancedSettings makes it possible to configure that the PLC
movement of an individual axis is not canceled if the touch probe is
deflected by another axis.
A faster acceleration and filter calculation for PLC movements can be
activated in addition to the configuration of a fast axis; See "Advanced
settings for individual axes" on page 638.
New: Referencing with external reference signal
Effective immediately, an external reference signal can be used instead of
the reference signal of the connected motor encoder to reference an
individual axis of the entire system (e.g. spindle); See "Referencing with
external reference signal" on page 1006.
New: Axis mirroring with new kinematic model
In the new kinematic model, an axis can also be mirrored within a kinematic
group without switching the kinematics; See "Axis mirroring on lathes (as of
NC software 548328-03)" on page 746.
New: Keeping spindle speed for rapid traverse constant
With the new machine parameter MP_freezeVconst you can prevent the
spindle from changing its speed during constant surface speed Vconst
according to the current diameter if there are several rapid traverse
movements. This can prevent unnecessary deceleration and acceleration of
the spindle during several successive rapid traverse movements; See
"Freeze spindle speed for rapid traverse" on page 1392.
Enhanced: Configuration of the nominal position value filters
The possible maximum value for the filter order was increased from 31 to
63 in the machine parameters MP_orderFilter1 and MP_orderFilter2,
which are effective for all axes; See "Nominal position value filter" on page
811.
MANUALplus 620 for retrofitting
The new MC 320T main computer supports purely analog drive control. The
axes are controlled exclusively through the analog nominal speed command
interface. The compact MC 320T main computer is integrated behind the
screen of the operating panel to save space.
New: Transferring the spindle speed and feed rate data to the PLC
With MP_readTsfData you can now configure whether the PLC will read
the data for feed rate and spindle speed shown in the dialog "Set T, S, F "
from the tables ch_tsf.mch and sp_tsf.msp; See "Transferring the spindle
speed and feed rate data to the PLC" on page 1406.
New: Transferring the display mode of the machine display to the PLC
The active display mode (e.g. "manual control," and "automatic") of the
dashboard can now be passed on to the PLC. This makes it possible to
switch the view of the machine display; See "Transfer display mode to PLC"
on page 1406.
New: Tool pocket preset by the PLC
In the machine parameter MP_setToolPlace you can now define a symbol
variable name under which the PLC can name the NC a tool pocket that is
then used and displayed by the user interface; See "Tool pocket preset by
the PLC" on page 1407.
