Products of Swiss company ABB in the field of electric motor control are well known to European consumer and on the EU market due to universal series of frequency inverters ABB ACS150, which are widely used for electric motor control in various systems, including pumping and ventilation equipment.
However, it is worth saying that ABB ACS150 frequency inverters are a universal type of equipment and are able to control various loads, but their use for controlling pump and ventilation equipment can not always be called optimal due to the lack of specific settings and operating modes specific to electric motors working in ventilation systems and together with pumps.
For such applications, the company has developed a specialized series of ABB ACS310 frequency inverters, which are designed to control motors with dynamically changing load, respectively variable torque, as well as having additional functions and modes that:
- allow you to select the optimum acceleration and braking curve for the electric motor;
- provide the option of controlling several pump or ventilation motors with a single inverter;
- have built-in PID feedback control of one or more monitored parameters. Typically this is system pressure or flow rate;
- are equipped with built-in economic effect calculation and indication functions, which helps in fine-tuning of the equipment;
- are housed in a sufficiently compact enclosure that can be mounted on a rail or in a switch cabinet.
Virtually any ABB ACS310 frequency inverter is ready for use in such systems and does not require long setup times as it has a built-in assistant or assistant. It allows key parameters to be entered by simply answering a number of control system queries.
These frequency inverters also have an advanced fine tuning system and feedback functions that can be carried out both directly from an in-house or advanced smart control panel as well as via software. For companies that need to install a large number of these frequency inverters on the same type of ventilation or pump equipment, it is possible to transfer the settings through a special additional FlashDrop panel, which is connected to a special connector on the front of the device. Through this panel it is possible to configure the basic parameters of the device, as well as to transfer the settings to another device or to a computer and from the computer after making the necessary changes.
Functional features of ABB ACS310 frequency inverters
Among the unique features that distinguish the equipment of this series from its counterparts are:
- the function of separate control of several pumps or fans from a single frequency inverter;
- smooth control of the equipment, which not only extends the service life of the electric motor, but also of the system it serves;
- built-in motor protection protocols depending on the operating mode of the pump;
- possibility to connect several PID controllers to control various state parameters of the working environment;
- built-in power saving functions at partial load;
- motor protection against incorrect connection, jamming, short-circuit, overheating;
- automatic control of the electric motor cooling fan.
The field of application of specialized frequency inverters of 310 series includes a number of specific tasks, including:
- control of electric motors for ventilation of facilities of various sizes;
- control of irrigation and irrigation system operation;
- cascade water pressure support in tall buildings;
- maintaining the set liquid level in the storage tank;
- use in industrial forced ventilation systems in technological processes, including hot air.
Unlike the ABB ACS310 common industrial compact series, the 310 series can be configured using several methods, including remote control protocols.
The inverter can be connected via several remote control and monitoring interfaces, while not excluding the possibility of direct control via the built-in panel, e.g. during maintenance or in case of emergency situations.
