Appendix 4. Explanation of Large Capacity Spindle Unit Specifications
A4 - 2
Appendix 4-1 Explanation of large capacity spindle unit specifications
Appendix 4-1-1 Outline
The MDS-B-SPA Series large capacity spindle unit (37KW, 45KW, 55KW) is an expanded capacity
version of the MDS-C1-SPA Series standard spindle unit (30KW or less).
Additional items related to the increased capacity are explained in this section.

(Note) Use the MDS-C1-CV-370 for the power supply unit 37kW.
Appendix 4-1-3 Selection of AC reactor (B-AL), contactor and NFB
Always mount the AC reactor and contactor shown below on the input side of each power supply unit
(B-CVE-450, 550).
(Note 1) Always mount one contactor for each power supply unit when using the MDS-B-CVE-450 or
550. The power supply unit could be damaged if the contactor is omitted or shared with
another unit.)
(Note 2) Always mount one AC reactor for each power supply unit. The power supply unit could be
damaged if the AC reactor is omitted or shared.
The selection of the NFB when using only one power supply unit is shown below for reference.

(Note) Even when OFF, an earth leakage current of maximum 15mA flows at the coil connection
terminal MC1 for the power supply unit's external contactor. Thus, when using a contactor
other than that recommended above, do not use the contactor that can be turned ON at 15mA
or less or cannot be turned OFF at 15mA. When using a contactor with an internal electronic
circuit, consult with the contactor manufacturer and make sure that the contactor will operate
correctly even if an earth leakage current of 15mA or less flows.
