Version 3:
The parameters correspond to those of version 2 plus:
Approach mode
Variant 3 only affects modulo following axes that are coupled to modulo leading axes. Time
optimization takes account of velocity limits of the following axis.

The following modes can be used:
"NOC" Block change takes place immediately
"FINE" Block change is performed in "Fine

"IPOSTOP" Block change is performed for
setpoint-based synchronism
