MotionPLC GEL 8240

motion_line

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.

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.


action_pos1 action_pos2 action_pos3 action_pos4 action_pos6 action_pos5
Instruction list (IL)

An instruction list (German: Anweisungsliste AWL) 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

Ladder diagram (LD)

The ladder diagram (German: Kontaktplan KOP), 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 (German Funktionsplan FUP) 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 (German: Ablaufsprache AS) is a graphics-oriented language to describe the sequential execution of different actions in a program.

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.

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
noname

Curve editor example


  • 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.
