VFD Drives System

Today, manufacturers like Gozuk offer a well defined life cycle management plan which ensures that any VFD is maintained to the highest standards, thereby ensuring that the risk of failure is minimized. The life cycle management plan looks after all likely areas of VFD failure and makes sure there is a plan in place to combat any risk.
For example, inadequate cooling is a common source of failure. If VFDs are not maintained according to the manufacturer`s maintenance schedules - such as regular replacement of air filters and annual checking and cleaning of heat sink fins - then insufficient air flows through the VFD, causing failure.
However, there comes a point in any product`s life cycle when it has to be phased out as newer models with the latest technology just make the support of existing technology counter-productive.
It is at this point that taking out the old VFD and fitting a new VFD becomes the most economical option. Some manufacturers are developing services in anticipation of their legacy products being retrofitted.
In a retrofit project, existing cabling, motors and cabinets often remain in use, while the VFD or VFD system is replaced either completely or partly. Retrofitting is typically carried out during planned production shutdowns, without causing extra production downtime.
For example, if a plant is using an early ABB VFD such as the SAMI STAR, then a retrofit could not be easier. ABB has developed a specific retrofit service that comprises engineering expertise and a VFDs retrofit kit. ABB engineers assess the current VFD installation and recommend the appropriately dimensioned retrofit kit. more from VFDs.in
