Direct Drive Motor Specifications and Instruction Manual
5 Selection
5.1 Selection of the Power Supply Unit
(Only MDS-E-V1/V2 and MDS-D2-V1/V2)
For the power supply unit, calculate the spindle motor output, servo motor output and direct-drive motor output each, and
select the capacity satisfying the required rated capacity and the maximum momentary output. For details on the
calculation method of motor output and selecting method for motors other than a direct-drive motor, refer to "MDS-E/EH
Series Specifications Manual (IB-1501226(ENG))" or "MDS-D2/DH2 Series Specifications Manual (IB-1501124(ENG))".
5.1.1 Calculation of Direct-drive Motor Output
(1) Selection with rated output
(2) Selection with maximum momentary output
For the rated output and maximum momentary at the maximum speed of the direct-drive motor, calculate from the output
characteristics of each motor.
