230 VAC, 3 Ph 3.32
A three-axis system comprising of two SEC-SDDR2/4-SA drives and one SEC-SDDR8/14-SA drive, all operating on 115 VAC single-phase.
– Line filter required: One SEC-SDD-LF15
[0.29 x 2 + 0.58 = 1.16 kVA]
In the case of a system using multiple SEC-SDD ServoWire drives, they may share one line filter per cabinet. When selecting the line filter size,
the fact that all drives/motors will not be operating at the same time needs to be taken into account.
Suitable for typical point-to-point motion
Suitable for continuous regenerative and overhauling loads

System Examples
Example #1
Example #2
An eight-axis system comprising of eight SEC-SDDR14/24-SA drives operating on 230 VAC, three-phase.
– Line filter required: SEC-SDD-LF30X (one filter would be required if 4 drives are operating at a time).
[3.32 x 8 x 1.7321 = 46 kVA assuming all 8 drives operate simultaneously.
If 4 drives operate at a time, the power dissipation would be 11.5 kVA]
