Technical information

version 04.05

General information

The controllers have an integrated PLC, field bus systems
and multi-axis control with a maximum of 11 controlled
axes (max 3 with ± 10 V and max. 8 with CAN bus). 64 axes
altogether can be controlled via the CAN bus (without
feedback). Additional inputs and outputs permit several
CAN REMOTE I/Os with up to 64 inputs or outputs per
node and up to 64 node addresses.
The standard CoDeSys programming environment runs in
parallel with the multi-axis control and offers full
transparency for all parameters. Parametrization of all 7
axes is effected by a PC tool and offers menu-guidance for
comfortable setting of the usual parameters.
The standard programming environment in acc. with IEC
61131-3 includes a library of ready-made and powerful
technology functions for terminal programming and
automatic motion control.
Up to four different communication channels are available
with one interface enabling all conventional field bus
systems (PROFIBUS-DP, DeviceNet,...) to be used.
The field bus modules can be retrofitted or replaced at any
time without the need to modify the PLC program.
The MotionPLCs differ only in design (see below).

PLC programming environment

PLC programming environment

IEC 1131-3 is an international standard for programming
languages adapted to stored-program control units. The
programming languages realized in CoDeSys are in
conformity with the requirements of the standard. They
can be mixed whenever needed and are partially
convertible.

Instruction list (IL)

An instruction list (IL) is composed of a sequence of
instructions. Each instruction begins in a new line and
consists of an operator and - depending on the type of
operation - of one or several operands separated by
commas.

Ladder diagram (LD)

The ladder diagram, too, is a graphics-oriented program­ming language which is basically similar to an electrical
circuit.
It consists of a series of networks. A network is limited on
the right and left side of the plan by a vertical current path.
In between, there is a circuit comprising contacts,
inductances and connecting lines.

Function block diagram (FBD)

The function block diagram is another graphics-oriented
programming language. It is organized by lines and uses a
list of networks, each containing a structure representing
respectively a logical or an arithmetical expression, the
recall of a function block, a jump or a return instruction.

Structured text (ST)

The structured text is a series of instructions which can be
executed - as in the higher programming languages ­depending on a condition („IF..THEN..ELSE“) or iteratively
(WHILE..DO).

Sequential function chart (SFC)

The sequential function chart is a graphics-oriented
language to describe the sequential execution of different
actions in a program.

DS22-824x(04.05)

Continuous Function Chart Editor (CFC)

The essential difference with regard to the FBD is the free
arrangement of function blocks. CFC is a useful
enlargement of the IEC 1131-3 standard.

Operating software

Technological cam-plate function

• Curve modification without set-up times

• Reduced jerking during movements due to harmonic

and cycloid curve shapes

• Engagement and disengagement of the slave axis

• Virtual master function:

permits displacement of the curve drive

• Dynamic adaptation of curve shapes:
lengthening, shortening, etc.

within the scope of supply

BB2100K operating software (curve editor)

The BB2100K operating software can be used to define
the desired curve characteristics on a PC. The PC is
connected to the MotionCard via the serial interface. The
parameter editor for the servo-converter LD 2000 can also
be started out of this program. Other program
characteristics:

− System parameter editor

− Oscilloscope function

− Setting of range signals via mouse-click

− Individual programming due to free editing of program

texts

− Assistance with the analysis of curves (position,
speed, acceleration and torque)

− Graphics-aided editing of parameters for special
applications (e.g. rotating cutter and flying saw)

Application example

Application of adhesive on a car door

An glue dispenser with a three-axis portal equipped with servo drives and amplifiers is controlled by the MotionPLC in
such a way that the tool follows a trajectory in three dimensions which has been fixed beforehand by a small number of
essential tool center points in the teach-in mode.
