6.6.1 General MD bits (general bits)

Acknowledging the channel-specific cancel alarm via operator panel (BT)

Cancel alarms are acknowledged with the key. With MD 5008 bit 0 you can

set whether the key affects all channel-specific alarms or only those of the

selected (actual channel). Other channel alarms are acknowledged NC-

specifically.

Acknowledging channel-specific cancel alarms via the PLC

Channel-specific cancel alarms can be acknowledged via the PLC user interface

signal ”CANCEL” (DB 10 - DB 13) in the same way as with the reset key.

Bit 7 5 axis tool linear compensation

The 5 axis tool linear compensation corrects the programmed block end points

depending on the type of milling head used in short linear blocks with G01. If a

tool breaks, the milling machine can carry on from the point of the breakage if

a tool with the programmed radius but a different length is chucked. The

difference in length is entered as the tool length compensation in tool offset

type 40.

This is only possible if the programs have been written taking the tool length

and cutter radius into consideration.

The 5 axis tool length compensation is called up with NC MD 5010 and tool

type 40. The tool length (different in length as compared with the old tool) is

stored in tool parameter P2. In the case of milling machines with a nutating

head, the permanent nutating angle must also be entered in MD 20.
