RESET commands
The following Reset commands are available:
• Interface signal DB11, ... DBX0.7 ("Mode group reset")
• Interface signal DB21, ... DBX7.7 ("Reset")
For a further explanation of the individual signals, refer to the data lists.
A RESET command can be used to interrupt an active part program or a part program block
(in MDA).
After execution of the Reset command, interface signal DB21, ... DBX35.7 ("Channel status
Reset") is set.

• Axes and, if they exist, spindles in the channel are decelerated along a braking ramp.
• Any auxiliary functions that have not yet been output at this point are not longer output.
• The block indicator is reset to the beginning of the part program.
• All Reset alarms (channelspecific, axisspecific, spindlespecific) are cleared from the
