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.)
