MDS-C1-SPA Series spindle drive unit of 5.5kw or smaller are not available. Therefore, when the
spindle drive unit of 3.7kw or smaller is required, use a spindle unit of MDS-B-SPA Series. In this section,
the items about MDS-B-SPA which must be added to C1-SPA are explained. Use MDS-C1-CV for the
power supply unit to be combined.
