Operating Instructions, 08/2013, 6FC5397-8EP40-0BA0

Description:

This machine data defines the M function number with which the switchover to

controlled spindle/axis mode is to be carried out.

The M number defined in the machine data replaces M29 in external language

mode.

Pre-defined M numbers, such as M00,M1,M2,M3, etc., are not allowed as M num-

bers.

MD26008 $MC_NIBBLE_PUNCH_CODE

Description: This MD is only significant if the functions 'Tool management'/'flat D num-

bers' are inactive.

FALSE

The contents of the address extensions of the NC addresses T and M 'tool

change command number' are not evaluated by the NCK. The PLC decides on the

significance of the programmed extension.

TRUE

The address extensions of the NC addresses T and M 'tool change command num-

ber' - 'tool change command number'=TOOL_CHANGE_M_CODE with 6 as the default

value - are interpreted as spindle numbers.

NCK treats the extension in the same way as the active functions 'tool man-

agement' and 'flat D number management'.

That is, the programmed D number always refers to the T number of the pro-

grammed main spindle number.
