Improvements:
n MP860: Define axis as torque-master-slave axis
n MP2900: Torque bias of the torque-master-slave control
n MP2910: Gain in the torque-master-slave control
n MP2920: Torque distribution of the torque-master-slave control
n MP2930: Speed rating factor of the torque-master-slave control
n MP7160 bit 1: Limiting the spindle speed during rigid tapping
n MP7263 bit 0: Display POCKET TABLE soft key
n MP7440 bit 6: Activating M134
n MP7441 bit 0: Suppress error message when machining cycle is called
without M3 or M4
n MP7683 bit 4: Edit pallet table
n Indication of position of machining plane expanded
n FN17 ID50: Overwrite data in tool table
n Module 9092, 9093: Element numbers for tool number and index
n Module 9147: Assign new Ref value
n Module 9155: Switch axis from controlled/uncontrolled state
n Module 9156: Switch axis from uncontrolled/controlled state
n Module 9220: Traversing the reference marks in each operating mode and
with PLC axes
n Module 9225: Compensation value for zero pulse
n Master-slave torque control
n ISO: With G36 (spindle orientation) it is possible to program a Q parameter
as an angular value.
n ISO: In cycle G80, a feed rate and a safety clearance can be programmed as
an option.
n Cycle 202, 204: Input parameters for angle in oriented spindle stop
n Several pocket tables possible
n M104 reactivates the manually set datum of all axes
n The ID number of the DSP software is shown in the system info
n Automatic tool compensation and monitoring of the breakage tolerance in
the touch-probe cycles 421 to 426
n With the soft key EDIT PALLET, the current pallet table can be edited in
pallet operation.
n Face milling: With M128 in connection with LN blocks, the tool is held
perpendicular to the contour.
n Peripheral milling: With M128 in connection with RR/RL, the negative radius
oversize (DR) is compensated perpendicular to the machining and tool
direction.
