Appendix 3-1-2 Selection example
(Example 1) Spindle motor : SJ-V18.5-03 30-minute rated output 11kW
Spindle drive unit:
MDS-C1-SPA-220
(1) Selection with rated capacity
Σ(Spindle motor output) = 11kW
→ "MDS-C1-CV-110" that has the selection capacity of 11kW,
or larger unit is required.
(2) Selection with spindle drive unit
According to the table in the previous section, "MDS-C1-CV-150" or larger unit is required for
the power supply unit which can be combined with
"MDS-C1-SPA-220".
(3) Overall selection
Select the power supply unit "MDS-C1-CV-150" that meets the conditions (1) and (2).
(Example 2) Spindle motor: No.1 SJ-V5.5-01 30-minute rated output 5.5kW
No.2 SJ-V18.5-03 30-minute rated output 11kW
Spindle drive unit:
No.1 MDS-C1-SPA-55
No.2 MDS-C1-SPA-220
(1) Selection with rated capacity
Σ(Spindle motor output) = 5.5kW + 11kW = 16.5kW
→"MDS-C1-CV-185" that has the selection
capacity of 16.5kW, or larger unit is
required.
(2) Selection with spindle drive unit
No.1 According to the table in the previous section, "MDS-C1-CV-37" or larger unit is required
for the power supply unit which can be combined with "MDS-C1-SPA-75".
No.2 According to the table in the previous section, "MDS-C1-CV-150" or larger unit is required
for the power supply unit which can be combined with "MDS-C1-SPA-75".
(3) Overall selection
