Programmable Logic Control --> Speicherprogrammierbare
Steuerung. Component of the --> NC: Programmable controller for
processing the control logic on the machine tool.
• SINUMERIK FM--NC: The PLC user program, the user data and
the basic PLC program are stored together in the PLC user
memory of the CPU 314.
S7--CPU314 has a user memory of 24 KB for this purpose.
• SINUMERIK 840D: The PLC user program, the user data and
the basic PLC program are stored together in the PLC user
memory. The PLC user memory can be expanded up to 128 KB.
• SINUMERIK 810D: The PLC user program, the user data and
the basic PLC program are stored together in the PLC user
memory of the CPU 314. The basic
version of the S7--CPU314 has a user memory of
64 KB which can be optionally expanded up to 128 KB.
The PLC is programmed with the STEP 7 software. The STEP 7
programming software is based on the standard WINDOWS
operating system and incorporates the functionality of STEP 5
programming with innovative expansions and developments.
A coordinate system which defines the position of a point on a plane
in terms of its distance from the origin and the angle formed by the
radius vector with a defined axis.
Polynomial interpolation provides a means of generating a very wide
range of curves, including straight- -line, parabolic and
exponential functions (SINUMERIK 840D/810D).
An axis which performs an auxiliary movement on a machine tool
(e.g. tool magazine, pallet transport). Positioning axes are axes that
do not interpolate with the --> path axes.
The action of switching the control off and then on again.
