4.3.5 Star/Delta Starter or Soft Starter not Required
When larger motors are started, it is necessary in many countries to use equipment that limits the start-up current. In more tradi-
tional systems, a star/delta starter or soft starter is widely used. Such motor starters are not required if a drive is used.
As shown in the following illustration, a drive does not consume more than rated current.

4.4 Power Drive Systems
4.4.1 Ecodesign for Power Drive Systems
The Ecodesign Directive is the legislative framework that sets requirements on all energy-related products in the domestic, commer-
cial, and industrial sectors throughout Europe.
The Ecodesign requirements are only mandatory within the European Union. These requirements are like the legislative require-
ments for energy-related products which apply in North America and Australia.
Terms like Complete Drive Module (CDM) and Power Drive Systems (PDS) are used to dene the elements in the design. The objec-
tive is to make more ecient and fewer energy consuming designs.
The CDM contains the drive controller as well as auxiliary devices and input components.
