ASIMA II
![../../fileadmin/user upload/LD Didactic/Bilder/Neuheiten BQ 2016/Elektrotechnik ASIMA II 02](fileadmin/_processed_/csm_Elektrotechnik_ASIMA_II_02_af9aace96c.jpg)
ASIMA II (Advanced Plant Simulator) is the optimal Simulator for Systems for LOGO! S7–1200 and S7-1500. LD DIDACTIC has completely reworked the ASIMA II.
There are still 33 various systems available. These can be set up via a code switch and illustrated via the coloured masks. The spectrum ranges from "Testing PLC Functions" to "more complex systems with regulators". The latest integrated interfaces for USB/Ethernet make it possible to expand the ASIMA II for new tasks.
The device is designed for apprentice and student experiments. Practical tasks
challenge the student to solve this control or regulating problem with his or her own programme. A solution approach is supplied as a file.
The ASIMA II can be combined with COM3LAB Teaching Software.

Fault localisation in contactor circuits. Compact device with integrated fault simulation.
The device has been reworked by LD DIDACTIC so that the highest safety requirements have been fulfilled. The core of the device is the front containing a large number of lead-throughs behind which the measuring and connecting points for the contactor circuits are located.
By applying various masks, only the measuring and connection points remain available that are relevant to the circuit depicted on the mask. All points not required remain behind the mask.

The Machinery System 4.0 has been developed for the latest demands for modern drive units.
The electrical machine is now always considered to be more than just a stand alone units. Two cause variables force the ongoing development of machinery:
ENERGY EFFICIENCY
An increase in efficiency can no longer be achieved by the machine on its own today. The drive unit, in principle the conjunction of the electrical power components with the machine, considerably increases the whole efficiency.
AUTOMATION
An increasing number of drive units require increased dynamics at increased torque and, simultaneously, a reduction in design volumes. These demands can only be achieved with optimised drive units. The necessity for examining a complete drive unit system in the school and during studies has increased considerably.
Modern drive unit systems also create an large integral hazard potential. In order to contain such hazards, many standards for these drive units have been created or supplemented such as e.g.:
- Hazards from leakage current in machinery and controlling
- Hazards from circuit feedback
- Hazards from interference signals from machinery and controlling
Topics (in extracts):
- Design and mode of operation from machinery
- Behaviour of a machine as a motor
- Behaviour of a machine as a generator
- Possibilities for setting the rpms
- Energy turnover

More safety with electrical machines
Machine bench and locking system
The safety for the machine is increased by securing the machinery on a bench.
Mechanical impulses which occur from friction from IPM and synchronised motors are absorbed on both sides by the bench and the mechanical locking. The new bench enables the design of the machinery sets in both directions.
Machinery testing system
The actual measuring for the pupils and students is visible due to the new design of the drive unit. The measuring system can now be harmonised for improving the measuring of the torque. In addition there is a mechanical zero point setting as well as the possibility to inspect and calibrate the measurements with weights.
Protection against rotating parts
The shaft is connected via a hood, which is positioned on its own plinth, with the plinth of the machine and pendulum machine. The drive unit shaft can only be touched after dismantling the drive unit system. In addition, the locking system for the plinth is electronically monitored i.e. as soon as the plinth is separated, then the system will be switched off.
Equipotential bonding
The supplementary equipotential bonding is necessary for protecting people and systems. A break in the protective earth will energise the machine or even the complete system as the leakage current can be conducted directly via the stator to the motor and the system or plant. A hazard can then only be prevented when the complete system in designed with a very low resistance earth potential.
EMV
All the motors are isolated against the plinth so that unnecessary slipping cannot increase the interference signals and that wayward leakage current cannot affect the measuring sensors. This is a prerequisite for Industry 4.0 capable frequency converters and servo-assisted drive units as well as the associated rpm-revolution angle and position sensors.
Machinery
All the machines will only be designed with one shaft end. The terminal block will be positioned on the top for flexible setting up of experiments.
