This command must be programmed in advance also when writing zero offsets and tool
offsets if the new values are not to take effect until after this block.
The STOP-DEC command must always be given in a
Example:
M94
@714
@123 R60 K100
@715
If the angle of rotation of the settable or programmable coordinate rotation is loaded with
the help of the CL 800 language, this angle value is used immediately for the calculation.
This can result in this angle being included in earlier traversing blocks.
If the angle is not to be valid until the next block, all the previous blocks must be executed
(empty buffer).
This can be achieved by programming STOP DEC1 also with selected TNRC/CRC.
Decoding is not reactivated until all buffer memories have been emptied before coordinate
rotation.
Example:
@715
@437 K0 K1 K1 R30
Note:
The command @715 must always be incorporated in the target code in an NC block of its
own. The command @714 can be used instead of the command @715. The precondition
here is that TNRC/CRC has previously been deselected.

This function is relevant to the electronic gearbox (ELG) only. The leading axis is defined
as an axis. The following axis is defined with<Value 1> and the leading axis with <Value
2>. The required transmission ratio K
