A.7 Mains filters
The following tables provide an initial estimation of which mains filter will probably meet
the EMC requirements for a given requirement. The selection is to be checked by the
installer/operator. Under certain conditions it is possible to change to a smaller filter, or a
larger filter must be used.
Step Action Comment
1.
Select the table that corresponds to the rated current for your application.
2.
Add together the motor cable lengths for your application and go to the related
column or the next larger column.
3.
Select the corresponding environment for your application (residential C2 or
industrial C3).
4.
Select the maximum motor power stage clock frequency that occurs in your
application.
5.
Read off the article designation for the mains filter.
6.
For systems with a larger number of axes or long motor cables, check the mains
filter selected according to appendix A7.2.
7.
Demonstrate compliance with EMC requirements by measurement.
Example
The system on which the interference is to be suppressed consists of six axes each
with a motor cable length of 4 m and is operated with an automatically switching clock
frequency with a maximum of 8 kHz also in residential areas. The mains-side rated
current is 18 A.
y
Based on the rated current, the Table "Mains input current I
IN
≤ 25 A" is to be
selected.
y The sum of the motor cable lengths is 6 x 4 m = 24 m, the column "30" is to be
selected.
y
Residential environment = category C2
y
Maximum clock frequency = 8 kHz
y
The recommendation for the mains filter is EMC25.240-UR

A.6 Accessories
We have supplemented the ServoOne CM system with comprehensive accessories.
Important components are, e.g.:
y
Synchronous servomotors from the product ranges LSN/LST and LSP with
− Encoders of type resolver, hiperface © multiturn and hiperface © singleturn
y
Pre-assembled motor cable
y
Pre-assembled encoder cable
y
DriveManager 5 PC user software
y
Mains filter - reduces the cable-borne high-frequency interference from the drive
controller
(for use on the supply unit ServoOne CM-P)
y
Mains choke - reduces the distortion (THD) in the system and prolongs the life
of the axis controller (for usage on the ServoOne CM-P supply unit).
y
Braking resistor - converts surplus regenerated energy into heat and in this way
permits an even more dynamic movement process (for usage on the ServoOne
CM-P supply unit).
