Assignments in
Manual modes of
operation
In the manual operating modes, the peripheral user devices, such as the
monitor or keyboard unit, are assigned to a machining channel and a spindle.
The machining channel is specified in the PLC operands
NN_GenOmgManual and NN_GenChnManual, and the spindle in
NN_GenSpiManual.
The machining channel and the spindle are selected specifically for each
control.
Asynchronous
position
compensation
(additive
compensation)
The control supports asynchronous compensation. Asynchronous means that
compensation values are entered during machining.
The control supports:
 Asynchronous tool compensation: This compensation is assigned to a tool,
and corrects the tool lengths. The asynchronous tool compensation is
cleared during a tool change.
 Asynchronous position compensation: This type of compensation, also
known as additive compensation, is managed independently of channels in
tables, and is activated and deactivated via G command (G914). An
asynchronous position compensation is in effect until it is deactivated or
until the end of the program.
For compensation value tables for asynchronous position compensation, see
MP_System/Paths/CfgTablePath/Add_Cor*/path (*=1: machining channel 1;
*=2: machining channel 2; etc.)
If an asynchronous compensation is activated, deactivated or changed, then it
is "corrected" with the velocity defined in MP_feed.
