FR-D700 vs FR-CS80 and why the FR-D700 is superior to FR-CS80.

Introduction

We will be looking at two VFDs for this purposes – both of which are of the compact catagory. The intention is to provide factual clarity to aid in the decision making in the selection of these drives.

It is indicated that the FR-D700 is superior to the FR-CS80, and intentionally so, by design (as being confirmed by the MEU). The following is merely a summarized set of some of the points that is applicable to the comparison of these inverters.

  • FR-D700 is a level up from the FR-CS80 drive function wise  (also the CS80 has limited I/O)
  • FR-D700 is a more robust drive, can handle higher stress and temperature environments (50°C), whereas the CS80 drive is rated for 40°C environments
  • FR-D700 has an official life-time expectancy of 10 years, and a FR-CS80 has an official life-time expectancy of 5 years.

By these points alone – the price difference is already justified in most cases.

So what about the FREQROL drive hierarchy? (if cost wasn’t a factor in the selection process)

Below a rating @ class comparison for the purpose of indicating power output ranges of the selected drives;

In terms of current rating@class:

  • FR-CS80 – 10A@200Vac1ph and 29.5A@400Vac3ph
  • FR-D700 – 58A@200Vac3ph and 29.5A@400Vac3ph
  • FR-E700 – 60A@200Vac3ph and 30A@400Vac3ph

Considerations to be taken in terms or repairs (Compact vs Modular)

In terms of repairability:

  • FR-CS80 – compact – not economically repairable. Requires to be replaced.
  • FR-D700 – compact – not economically repairable. Requires to be replaced.
  • FR-E700 – partially modular – certain components can be replaced.
  • FR-F800 – fully modular – all parts can be replaced
  • FR-A800 – fully modular – all parts can be replaced

It must be pointed that the FR-CS80 drive is by no means a bad drive – and is still an excellent drive for your buck.
