EMC filter SED2
3-Phase
Motor
Figure 46. Typical Power Wiring for SED2 with EMC Filter.
Connecting Multiple Motors
The SED2 can control several motors in
parallel as long as all of the motors
have the same power rating. When
multiple motors connect to the SED2 in
parallel, the motors cannot operate
individually.
NOTES:
1. When determining the required
power, take into account the total
current from all the motors (or the
sum total of all ratings).
2. The sum of all individual motor
cable lengths must not exceed the
maximum motor cable length. (See
the Motor Cable Length section in
this manual.)
