Danfoss FCM 307 [7/106] Fcm series

Integration of frequency converter and motor

The Danfoss VLT frequency converter integrated onto

the asynchronous motor gives infinite speed control in

one unit.

The VLT DriveMotor FCM 300 Series is a very com-

pact alternative to the ordinary solution with VLT fre-

quency converter and motor as separate units. The

frequency converter is attached instead of the motor

terminal box, and it is no higher than the standard ter-

minal box, nor wider or longer than the motor (see

chapter 6).

Installation is made extremely easy. Panel space is not

a problem. There is no need for special details on wir-

ing to meet the EMC directive, since motor cables are

not necessary. The only connections are mains and

control connections.

Factory-set adaption between frequency converter

and motor gives precise and energy efficient control in

addition to eliminating pre-setting on site.

The FC motor can be used in stand alone SYSTEMs

with traditional control signals, such as start/stop sig-

nals, speed references and closed loop process con-

trol or in multiple drive SYSTEMs with control signals

distributed by a field bus.

Combination of fieldbus and traditional control signals

and closed loop PID control is possible.
