BDM: Base-Drive-Module
Basic drive unit consisting of the power part and the control electronic. i.e. frequency inverter -
build-in unit
CDM: Complete
-Drive-Module
Drive module consisting of: BDM (basic unit) and possible extensions i.e. cubicle including RFI-Filter,
AMF, line contactor, ...)
PDS
: Power-Drive-System
Drive system consisting of CDM (drive module), the motor, motor cable on site controlling, mains
transformer, ..... i.e. the complete electrical drive of a machine
The main differences for the use of frequency inverters result in difference regarding to the sales
methode and the area of duty:
1.) Use in domestic premises where the sales is generally done (unrestricted to every person)
For drives < 25 A the allowed interference limits are likely the same as to the standard
EN 55011 class B, that means: 66-56/56/60 dB(µV) quasi-peak and 30/37 dB(µV/m) at
10 m distance.
For drives ≥ 25 A the limits are related to the class A, that means: 79/73/73 dB(µV) quasi-peak
and 30/37 dB(µV/m) at 30 m distance.
2.) Use in domestic premises where the sales is restricted to qualified and trained EMC resellers
All drives must keep the interference limit of the so far used class A,
that means: 79/73/73 dB(µV) quasi-peak and 30/37 dB(µV/m) at 30 m distance
3.) Use in industrial premises with quiet enough noise supression
