Advantages with ASTAT®:

• Fewer and better components result in more up-time.

• Operational diagnostics will speed-up fault tracing.

• Multipurpose spares will reduce parts in stock.

• The PC-program for maintenance can be installed in

a ground level computer. Nobody has to visit the crane

first to find the problem.

Digital ASTAT motion control is superior to other

techniques and it increases the operational results to the

limits of the crane itself. For you as a user it will create:

• Increased productivity. The operator moves the

crane without jogging, i.e. with one single movement.

• Prolonged lifetime. Smooth acceleration and

retardation decreases torque peaks.

• Special functions reduce rope and brake wear.

• Satisfied operators. Motion control is possible down

to increments of only one cm. Try to do such a small step

without the ASTAT system!

• Excellent control features permit higher speed

during automatic control.

When to select ASTAT® ?

ASTAT is suitable for crane control in demanding

environments, when larger motor powers must be

handled, for retrofits or when automating one or more

cranes.

The ASTAT Digital Crane Motion Controller has

better control and information properties

compared to earlier controllers. Equally

important is the focus on quality of hardware

components. The digital controller can be

mounted on a steel plant crane in hot countries

such as India without extra cooling or air

conditioning. This capability provides additional

benefits to worldwide industrial crane users.

i.e. The crane control system must withstand

dirty, hot and cold environments in addition to

difficult power supply systems. This has forced

us to integrate functions like brake control, time

relays, logic control and thermistor relays into

the ASTAT controller. Generic products with the

same robustness as the ASTAT controller are

difficult to find. With this level of integration we

offer a complete, fully tested motion control system.

Slip-ring motors may be produced with small

internal rotor losses. This is important in crane

applications with multiple motors and a high

demand for good motion control. As well as

being ideal for crane applications, slip-ring

motors are low on maintenance with brushes

being exchanged only every 5 to 10 years.

ASTAT uses the slip-rings for measurement of

the rotor frequency and from this calculates the

speed. In most cases no tachometer or pulse

encoder is necessary.

The operator controls the crane motion, while

all rotor contactors are optimized by ASTAT, as

an integrated part of the current control. This

results in dramatically reduced wear of

contactors and crane mechanical parts. Crane

maintenance costs will therefore be reduced.

Powerful, responsive and accurate control of

industrial cranes in all types of environment.

For both new and retrofit installations.

ASTAT® for industry!

ASTAT, with slip-ring motors, has become the

leading technology for new heavy industrial

cranes in the growth regions of the world.

In Europe, ASTAT is mostly used for retrofit

installations or when normal industrial drives

are unable to fulfil the requirements.

We supply ASTAT solutions for applications up

to 4000 A or 4700 kVA.

If the protection against direct contact according to DIN

VDE 0160 is required, this has to be ensured by the user

(e.g. by incorporating the elements in a switch-gear cabinet). The devices are designed for pollution severity 2 in

accordance with DIN VDE 0110 Part 1. If higher pollution

is expected, the devices must be installed in appropriate

housings.

The user has to guarantee that the devices and the components belonging to them are mounted following these

regulations. For operating the machines and installations,

other national and international relevant regulations, concerning prevention of accidents and using technical working means, also have to be met.

Devices of Advant Controller 31 Series (AC31) are designed according to IEC 1131 Part 2. Meeting this regulation, they are classified in overvoltage category II which is

in conformance with DIN VDE 0110 Part 2.

For the direct connection of AC31 devices, which are powered with or coupled to AC line voltages of overvoltage

category III, appropriate protection measures corresponding to overvoltage category II according to IEC-Report 664/

1980 and DIN VDE 0100 Part 1 are to install.

Regulations

Concerning the Setting up of Installations

Apart from the basic “Regulations of the Setting up of

Power Installations” DIN VDE*0100 and for “The Rating

of Creepage Distances and Clearances” DIN VDE 0110

Part 1 and Part 2 the regulations “The Equipment of Power Installations with Electrical Components” DIN VDE 0160

in conjunction with DIN VDE 0660 Part 500 have to be

taken into due consideration.

Further attention has to be paid to DIN VDE 0113 Part 1

and Part 200 in case of the control of working and processing machines. If operating elements are to be mounted near parts with dangerous contact voltage DIN VDE

0106 Part 100 is additionally relevant.

If the protection against direct contact according to DIN

VDE 0160 is required, this has to be ensured by the user

(e.g. by incorporating the elements in a switch-gear cabinet). The devices are designed for pollution severity 2 in

accordance with DIN VDE 0110 Part 1. If higher pollution

is expected, the devices must be installed in appropriate housings.

Program execution

The central unit microprocessor ensures the cyclic execution of the system as shown in

Figure 1-4.

The internal processing:

– PLC monitoring and control

– and processing requests from the terminal operator,

is executed in parallel with the previously described cycle.

The main program is processed sequentially. It may call up to a maximum of 12 sub-programs.

Each sub-program may be called numerous times in the main program.

Three types of interruptions may be executed parallel to the main program:

– A cyclic interruption

– A warning interruption triggered by an event on the I 62.03 input

– A warning interruption triggered by an event on the I 62.02 input

The interruptions have priority over the main program execution. If all three interruptions are

triggered simultaneously then the interruption triggered by I 62.03 has priority over the I 62.02

input interruption which in turn has priority over the cyclic interruption. Once an interruption has

been launched it cannot be interrupted by another (Figure 1-5).

The execution duration of a cycle (bus cycle + program cycle) is controlled by the central unit.

Any excess of the cycle time defined by the user in AC31GRAF is signaled by the ERR Led, at

the front of the central unit, as of the first program cycle.

Functional diagram

The 40 and 50 series central units memory is composed of two distinct areas:

– A SRAM memory where the user program and data is loaded.

– A Flash EPROM memory which contains:

– a backup of the user program with the program constants,

– the configuration data,

– and the system program protected against access from the user program.

An incorporated battery, which is available only in the 50 series, also enables the backup of

internal variables.

The user program is a set of universal functions conceived by the constructor to cover all

applications and ensure all the basic PLC functions. It is developed with the AC31GRAF

software. After being translated into instructions understable by the central unit it is loaded in

RUN or STOP mode into the SRAM and then saved from the SRAM to the Flash EPROM.

Thereby, at each program launch the user program, saved in the Flash EPROM, is copied to

the SRAM for processing by the microprocessor (Figure 1-3).

The structure of the system program memory, the user program, the inputs / outputs and

internal variables are described in the annex (mapping).
