Electrification and Controls Manufacturers Association (ECMA) members are the Industry’s leading suppliers of electrification and controlling devices. They supply solutions worldwide and in virtually every major manufacturing and distribution sector.
Devices that control, service and enhance productivity of industrial handling including:
The Mission of Electrification and Controls Manufacturers Association is to develop and promote safe and reliable control systems for use in material handling equipment of all types and sizes.
To be recognized as the guiding authority of electrical control systems for the material handling industry.
This standard applies to AC Inverters for use on electric overhead, monorail, and gantry traveling cranes. AC Inverters are also referred to as variable frequency drives, adjustable frequency drives, or variable speed drives.
This standard provides minimum requirements and guidelines for alternating current (AC) and direct current (DC) electrification systems for electric overhead, monorail, and gantry traveling cranes. Electrification systems include conductor bars, festoon systems, cable chains, spring driven reels, and motor driven reels.
This standard provides the minimum requirements and guidelines for cable-less controls of electric overhead traveling cranes. A cable-less control device as referenced in this standard uses radio
frequency signals to control the movements and actions of said cranes for applications such as material handling. This standard is referenced in
CMAA Specification #70,
Specifications for Top Running & Gantry Type Multiple Girder Electric Overhead Traveling Cranes, and
CMAA Specification #74,
Specifications for Top Running & Under Running Single Girder Electric Traveling Cranes Utilizing Under Running Trolley Hoist.
These specifications contain information and references specific to electric overhead traveling (EOT) cranes.
The question of Variable-Frequency Drive (VFD) shelf life is actually a question of capacitor shelf life. There is a point at which that spare drive on the shelf will require maintenance prior to applying rated line voltage. This white paper summarizes the issues and the solutions.
