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

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.

(Note 1) Connect the L11, L21 and MC1 external connections without removing the conductors connected between L21 and L22, L22 and MC2, and L11 and L12 of the MDS-B-CVE-450,
550.
(L12, L22 and MC2 are for special specifications, and normally, the external connection is not required.)
(Note 2) Always connect the contactor to MC1 so that it can be controlled with the drive unit's internal signal. The power supply unit could be damaged if the contactor is turned ON and OFF with a separate user-prepared sequence.
(Note 3) One end of the contactor coil is connected to the MC1 terminal and the other end is connected to the power supply. The phase on the side connected to the power supply must be different from the phase connected to the power supply unit's L21.

Appendix 4. Explanation of Large Capacity Spindle Unit Specifications
Appendix 4-1-11 Restrictions
(1) Mounting
Always mount the MDS-B-SP-370,450, 550 on the left of the power supply unit.
When using MDS-B-CVE-450, 550, always use the enclosed link bar to connect L+ and L- on the
MDS-B-SP-370, 450, 550.
(a) Layout when connecting only one spindle drive unit to power supply unit.
Mount the power supply on the right and the spindle drive unit on the left.
Always cut the panel according to the panel cut dimension drawings shown in Appendix 5-1-5.
<Example 1>
MDS-B-SP-450 MDS-B-CVE-450
(b) Layout when connecting multiple drive units to a large capacity power supply unit
The following number of servo/spindle drive units can be additionally connected.
•
When MDS-B-CVE-450 and MDS-B-SP-370 are combined, 9kW (=45kW–37kW+1kW)
worth of units.
•
When MDS-B-CVE-550 and MDS-B-SP-450 are combined, 11kW (=55kW–45kW+1kW)
worth of units.
•
When MDS-B-CVE-450 and MDS-B-SP-370 are combined, 19kW (=55kW–37kW+1kW)
worth of units.
In this case, arrange the MDS-B-SP-370, 450 to the left of MDS-B-CVE-450, 550 as shown in the panel cut dimension drawings in Appendix 5-1-5. Mount the additional drive units to the right of the MDS-B-CVE-450, 550.
If the spindle motor output differs from the spindle drive unit output, the above, excluding the layout, may not always apply. (This is because the power supply unit's output is determined by the motor output.)

Only one MDS-B-SP-370, 450, 550 can be connected to one MDS-B-CVE-450, 550.
(b) When using MDS-B-SP-370, 450 or 550, the following power supply unit must be selected.
•
When using MDS-B-SP-370: Select MDS-C1-CV-260 or more or MDS-B-CVE-450 or 550
•
When using MDS-B-SP-450: Select MDS-C1-CV-300 or more or MDS-B-CVE-450 or 550
•
When using MDS-B-SP-550: Select MDS-C1-CV-370 or more or MDS-B-CVE-450 or 550
Note that if the total of the servo/spindle motor output corresponds to the above power supply unit with the normal selection method, that capacity power supply unit can be selected.
When total of servo/spindle motor output is 23kW or less: Select MDS-C1-CV-260
When total of servo/spindle motor output is 23.1kW or more: Select power supply unit with normal selection method.
When total of servo/spindle motor output is 27kW or less: Select MDS-C1-CV-300
When total of servo/spindle motor output is 27.1kW or more: Select power supply unit with normal selection method.
When total of servo/spindle motor output is 31kW or less: Select MDS-C1-CV-370
When total of servo/spindle motor output is 31.1kW or more: Select power supply unit with normal selection method.
