Oriented spindle stop
Stops the workpiece spindle with a specified orientation angle, e.g., to perform an additional
machining operation at a specific position.
Oriented tool retraction
RETTOOL: If machining is interrupted (because of tool breakage, for example), a program
command can be used retract the tool with a defined orientation by a defined path.
Overall reset
During a general reset the following memories of the -> CPU are deleted:
• the -> working memory
• the read/write area of the -> load memory
• the -> system memory
• the -> backup memory
Override
Manual or programmable control feature, which enables the user to override programmed
feedrates or speeds in order to adapt them to a specific workpiece or material.
Parameters
• S7-300: A distinction is made between 2 type of parameter:
– Parameters of a STEP 7 instruction
A parameter of a STEP 7 instruction is the address of the operand to be processed or
a constant.
– Parameters of a -> parameter block
A parameter of a parameter block determines the behavior of a module.
• 840D:
– Control operating area
– Arithmetic parameter, for which the programmer of the parts program can assign or
request values as required in the program.
Parts program management
Part programs can be organized according to -> workpieces. The size of the user memory
determines the number of programs and the amount of data that can be managed. Each file
(programs and data) can be assigned a name comprising up to 24 alphanumeric characters.
Path axis
Path axes are all the machining axes in the -> channel, which are controlled by the ->
interpolator so that they start, accelerate, stop, and reach their end positions simultaneously.
