Configuration of the behavior with NC start

The response to NC machining program start is defined by the channel-specific machine
data.

It can be defined in this machine data whether or not the configured coupling parameters
Speed ratio, Type of coupling and Block change response may be influenced by the NC
parts program.
0: Coupling parameters can be changed by the NC parts program
1: Coupling parameters cannot be changed by the NC parts program. Attempts to make
changes are rejected with an alarm message.
