This Tech Tip is a follow on from parts 1 and 2 of previous titles ‘Connect Via Modbus with Red Lion and ABB’, and ‘Connect via Modbus – Part 2’.
We will be looking at creating a sample program to extract information from your ABB drive to your Red Lion device, that will include looking at the actual value references from your main drive such as frequency, motor speed, torque and current.
ABB have a wide range of Variable Speed Drives, most of which have a handy control panel for programming and displaying information. Due to the number of drives available, it can sometimes be confusing which control panels are compatible with certain models, so this Tech Tip will help you select the right control panel for the job.
With such a large operation, there is a reliance on consistent efficient power to keep costs low and running as efficiently as possible. The mine investigated solutions to replace its existing VSD to rectify issues related to harmonics, including noise and increased power usage and surges.
These days devices are coming out with all kinds of handy features, but sometimes you just want a basic unit for a basic job. The ACS480 is a new range of variable frequency drives from ABB and their claim is “efficiency and simplicity in a small package, delivered as effortlessly as possible”. In this quick road test we’ll look at these and see how it stacks up against their stated goals and their previous history of quality drives.
Australian and New Zealand Standard: Electrical Installations “Wiring Rules” (AS/NZS 3000:2018) has now been published, superseding all previous versions: AS/NZS 3000:2007. It’s a complete revision of the 2007 edition to improve the work methods and installation practices, that constitutes the minimum regulatory requirements for a safe electrical installation. Updates now reflect new technologies, equipment and improved installation practices for electrical installers and design engineers across the country.
Harsh environments similar to those found in water and wastewater facilities can affect the ability of an electrical enclosure to protect the controls contained within, leading to a multitude of problems. Problems can include dangerous system collapses, production downtime, personal injury, and increased long-term maintenance costs and losses in customers.
The sensor and metering technology – along with data analytics -- has made steady progress during recent decades. New, smarter devices and integrated systems are entering the market. Their ability to pick up, log, transmit and distribute data relevant for maintenance purposes is about to bring great efficiencies to plant…
In most HVAC applications the ACH550 is only used with a simple start/stop and a speed reference but for those more unique installs this drive is jam packed with features and here is just a few. Timed Functions Some applications may require a motor to run only between specific hours…
