Single-Phase, 200 VAC
*1. If you use the SGD7W-5R5A with a single-phase 200-VAC power supply input, derate the load ratio to 65%. An
example is given below. If the load ratio of the first axis is 90%, use a load ratio of 40% for the second axis so
that average load ratio for both axes is 65%.
((90% + 40%)/2 = 65%)
*2. This is the net value at the rated load. However, a load ratio of 65% was used for the SGD7W-5R5A.
270 VDC
* This is the net value at the rated load.
