traverse different machine axes.
Replacing the technology function "setpoint changeover" (TE5)
The "setpoint changeover" function replaces the technology function "setpoint changeover"
(TE5). Migration of the technology function to the functionality of the "setpoint changeover"
function means that you must make changes in the machine data and in the PLC user
program:
• Machine data MD63750 is no longer required.
• The meanings of various NC/PLC interface signals have changed.
• Alarms 70451 and 70452 are no longer applicable.
• A setpoint changeover with simulated axes (MD30130 = 0) is no longer supported.
• The known restrictions relating to the technology card function are no longer applicable.
