MOTION CONTROL FOR INDUSTRIAL AUTOMATION
The term MOTION CONTROL is used to define the set of electrical drives for speed control of AC, DC and brushless motors.
The systems we develop are used in the most modern industrial automation systems.
HVAC&R stands for “HEATING, VENTILATION, AIR CONDITIONING AND REFRIGERATION” and includes all heating, ventilation, air conditioning and cooling systems.
HVAC&R systems aim to ensure comfort in the tertiary and residential sectors (e.g. homes, hotels, offices and stores) or in contexts with high manufacturing standards (e.g. paper production industries, chemical processes).
In the context of heat pumps, the use of our inverters ensures particularly high seasonal performance, both in hot and cold.
RENEWABLE AND ALTERNATIVE ENERGIES.
Every day, the carbon dioxide we produce is released into the earth’s atmosphere, causing the so-called “global warming effect”.
An answer to this problem is to replace today’s technologies with alternatives that have equal or better performance, without emitting carbon dioxide: THE SO-CALLED ALTERNATIVE ENERGY
Super compact booster units: Motor-Pump-Inverter.
Simple and easy installation, pump intercommunication via MODBUS.
Efficient algorithm for pressure, flow and level control.
Various options are available: fieldbus integration, W-LAN, SMS alert.
⦁ Current is proportional to motor speed.
⦁ Pressure is proportional to the square of the motor speed.
⦁ Power is proportional to the cube of the motor speed.
⦁ The current variation is obtained by the variation of the motor speed: in this way the power absorbed by the motor is much reduced.
⦁ Energy expenditure is reduced by approximately 60% depending on the load conditions.
⦁ Savings on installed energy
⦁ Reduction in peak current and voltage drop.
⦁ Elimination of water hammering
⦁ Noise reduction
⦁ Load rephasing
⦁ V/Hz control for AC motors
⦁ Sensorless control for brushless motors
⦁ Sensorless vector control for AC motors
⦁ Differential pressure sensor
⦁ 10 V/ 4- 20 mA
⦁ Air velocity sensor
⦁ CO2 sensor – Humidity sensor
⦁ Air current control
⦁ Master-slave operation
We develop technologies that allow the modulation of the speed of the compressor motor and, consequently, allow to regulate the cooling capacity of the machine, managing at best the load variations.
We take advantage of the versatility of drives, using PLC applications to provide precision control and maximum dynamic performance and thus obtain the best possible control of speed, voltage or positioning depending on the activity required.
LOGIC LAB programming software allows the company to perform its own programming reducing start-up and project times.
Last but not least, COST (reduced programming, wiring and assembling times) and ENERGY SAVING.
Examples of control modes:
Drives provide servo control in press feed units and cut-to-length lines;
-drive in closed loop AC mode in cut-to-length lines
-in open loop AC control in a variety of applications from conveyors to other material handling tasks.
The control unit is the same for Afe and Inverter (only the software is different).
Possibility to obtain only the single units (power and regulation).
The system complies with the SAFETY TORQUE OFF standard.
TEXTILE MACHINES FOR YARN FINISHING AND SPINNING
A tunnel system with common power bus has been realized for the control of textile machines.
The rotating motor frame is fully automatic to ensure high flexibility, energy saving and allow frequent machine reconfigurations for dynamic production change.
The machine uses different types of motors:
-Synchronous with or without speed sensor
System specially designed for injection molding machines.
The guidance system controls the flow and pressure limit with PID function.
The hybrid solution: pump and screw control.
The driving system controls the management of speed profiles: the digital network between servo pumps, drivers and proportional distributor offers a high efficiency of communication with the IMM control and also allows monitoring and configuration of components directly from the control system.

The source must be equipped to be able to generate, transform, and distribute voltage to meet peak demand, whenever the need arises.
The demand charge, i.e., the user’s demand for power, would be reduced through the use of storage systems thus reducing their cost.
