2.1 General
2.1.1 Parameterization of the RESET response
The channel-specific basic position is activated via a RESET:
MD20150 $MC_GCODE_RESET_VALUES (RESET position of G groups)
The initial setting can be specified for exact stop and continuous path modes and exact stop
criterion.
Detailed description of initial settings can be found in:

(K1)
2.1.2 Block change and positioning axes
If path axes are traversed in continuous path mode in a part program, traversing positioning
axes can also simultaneously affect both the response of the path axes and the block
change.
A detailed description of the positioning axes can be found in:

/FB2/ Function Manual, Extended Functions; Positioning axes (P2)
2.1.3 Block change delay
Even if all path axes and special axes traversing in the part program block have satisfied
their specific block transition criteria, the block change can still be delayed due to other
unsatisfied conditions and/or active functions:
• Missing auxiliary function acknowledgement by the PLC
• Non-existent following blocks
• Active function: "Empty buffer"
Basic logic functions: Continuouspath Mode, Exact Stop, LookAhead (B1)
