Design

The GEL 8110 / 15 EcoController is designed for both single and double axis control. Up to 6 axes can be controlled via the CAN bus. The controller is suitable for controlling all AC/ DC motors and hydraulic drives. The controller offers a fast and economical solution to both simple and complex automation tasks.

The EcoController is designed for installation in a switchgear cabinet. It can be operated individually or cross-linked. At the core of the EcoController hardware is a fast 16-bit microprocessor and a powerful peripheral ASIC developed especially for the demands of motion automation. The housing is constructed of sheet metal (Zincor).

Inputs / Outputs
In the basic version, the controller has

• digital inputs (terminal strip G, J)
• digital outputs (terminal strip H, K) and
• combined inputs / outputs (terminal strip F)

Each output can drive a current of 300 mA. Groups of 8 outputs each can carry a current of 600 mA together and simultaneously. Available as options are:

• 48 digital inputs (connectors E2, E3) and
• 48 digital outputs (connectors A2, A3)

All digital outputs operate with 24 V levels common in industry. All digital outputs are short-circuit proof and protected against polarity reversal. One can choose between displaying the input status of 24 inputs or the output status of 24 outputs via 24 (programmable) LEDs.

Actual value acquisition
There are various encoder inputs available to record the actual values of rotation, distance, or angle

• up to two counting inputs for 5 V or 24 V incremental encoders
• up to two serial SSI inputs for absolute encoders in gray code (13 bits/25 bits)
• CAN bus
• and all combinations of the aforementioned actual value acquisitions

Communications interfaces
The controllers can easily be cross-linked with the aid of two shunt-connected, 9-pin D-subminiature connectors. Available are:

• two RS 485 and one RS 422/485 communications interfaces independent of one another (connector B1, B2)
• PROFIBUS DP (connector P) not shown in front view, explained in the section PROFIBUS DP
• one RS 232 interface and the CAN bus (connector C)
• InterBus-S (connector I)

PROFIBUS DP (plug P1 and P2)
The controller communicates as a DP-SLAVE with DP masters of category 1 and 2 and offers the services for cyclic data exchange (DataExchange), the Global_Control commands “Clear_Data”, “Freeze” and “Sync”, Read_Input, Read_Output as well as the Watchdog function. The max. transmission rate is 1.5 MBaud.

InterBus-S (plug I1 and I2)
The controller works as a remote bus participant with InterBus-S-Slave functionality for communication with a bus master. The InterBus-S can replace all parallel and digital I/O . Process data can be read and written via process data channel. The data I/O module can be replaced by the PROFIBUS DP or InterBus-S module.

Programming

A controller programme always is comprised of one or more sentences that can easily be modified, duplicated or expanded. The sentence structure is set down by the users themselves and can therefore be adapted to all the various requirements. Inputting the sentences is carried out via the GEL 8810 operator terminal.

Still more convenient is using the BB 8100 „Operating + Observing“ PC programme to edit, store and load the sentences into the controllers or to read them out from the controllers. Of course the controllers can also be configured via this programme. At the same time, input masks of the BB 8100 nominal value editor also automatically adapt themselves to the selected sentence structures.

The „Operating + Observing“ PC programme also allows you to carry out communication with an individually operated controller or with a complex controller network. An automatic backup function reads the data and configurations of all the controllers that are cross-linked and independently generates the files necessary for system management. The option of saving data onto storage media allows for a better overview of the diverse controller files. A flexible printer driver assists in documenting the site data.

System requirements for the BB 8100 PC programme

• 80386 PC or higher (MS-DOS 3.30 or higher)
• 3.5" floppy disk drive and hard disk
• RS 232 interface

If you are cross-linking several controllers, your PC requires an RS 485 interface. If your PC does not have such an interface, then we can offer you the following solutions:

• GEL 89010 V 24 / RS 485 converter incl. power supply unit
• GEL 89011 V 24 / RS 485 converter with electrical signal isolation incl. power supply unit, GEL 8810 operator terminal

GEL 8810 operator terminal

The GEL 8810 operator terminal with its front dimensions of 160 mm x 160 mm is designed for operating and observing in close proximity to the controller. The 18 mm x 18 mm quick stroke keys can be labelled with user-specific insertion strips.

The high-illumination, high-contrast display has an alphanumeric LCD dot matrix display ( 4 x 20 characters, 8 mm high) with LED background lighting. The self-explanatory display text (bilingual) uses menus to guide the user through the programming of functions and operating values. In addition, there are also convenient editing features such as:

• inserting sentences
• copying sentences, even beyond programme limits
• deleting sentences, programmes, units and the entire memory
• scrolling through memory contents, etc. With the EcoControllers machine parameters and nominal value programmes can be edited or actual and nominal values can be visualized.

The selection of and communication with up to 31 EcoControllers is carried out via the RS 485 interface.

Further information about the GEL 8810 operator terminal is available on a separate technical information.

General information

Nominal values
The sentence-oriented programming allows for programme processes to be entered quickly and simply. For this purpose, users have available to them 6416 nominal value storage locations that can be divided up into 99 programmes with up to 999 sentences per programme. A sentence can consist of the following nominal values:

• position / length
• quantity
• machinery functions
• speed
• autostarting time

Programme process control
In order to make programme structuring flexible, 4 commands can be be preset in the sentence in place of position values:

• CALL Pr. - subroutine call
• Jump Pr. - programme branch
• JMP Sentence - sentence in the programme
• IF E/A - branch depending on a signal

Drive control
The control of variable speed drives is carried out via up to 2 analogue outputs with a voltage spread of 0 to + 10 V and 0 to ± 10 V and a resolution of 1.22 mV. In addition, the following signals are transmitted:

• forwards / backwards
• release controller inhibit
• release brake

For the control of e.g. pole-changing motors, there are 2 x 4 range signals available with the following controlling functions:

• slow run/fast run
• forwards / backwards

The CAN bus interface controls our Series ND 31 servoconverter. All controlled variables for up to 8 axes are transmitted via the bus. Wiring thus becomes easier (encoder and analogue outputs are not connected).

Machine parameters (selection)

• power failure protection
• choice of encoder inputs (incremental / absolute)
• multipliers for nominal value, display, and nominal speed value
• zero-point adaption for absolute encoders
• correction value (e.g. for saw blade width)
• absolute / relative measure system / 2 reference measures
• residual value settlement
• control parameters (speed, acceleration / braking / jerk time)
• circular table positioning
• passwords for nominal values and machine parameters

Special functions

• linear path control
• change as desired between absolute / relative measure system during inputting of nominal values
• continuous sentence processing
• parking position
• range signals
• software limit switch
• trailing error control BH1

Control principle GEL 8110/8115
With the control principle used, a new, calculated nominal position value is cyclically specified for the drive and the resulting difference between actual and nominal values is evaluated by a programmable factor that is responsible for the control dynamics. In order to minimize the contouring distance, a calculated value for the speed is additionally added up (r.p.m. precontrol). Thus one has a very effective and individually adaptable control for the drives.

Acceleration and braking curve
The acceleration and braking curve for the drive is separately set down for each axis over the parameters to be specified:

• maximum and operating speed
• acceleration and braking in both forward and backward directions
• jerk (time)

The jerk is the size by which the acceleration changes, i.e. a measure for the steepness of acceleration and braking. By prescribing these values for the specific plant, the commissioning of the device and the optimization of the control response are considerably simplified. The positioning characteristic for the drive (e.g. soft start ) is set down simply by the suitable selection of the jerk parameter (see diagram „jerk-dependent positioning curves“).
