MITSUBISHI MDS-B-SP-260 CNC Spindle drive unit.

MITSUBISHI Electric MDS-B-SP-260 (MDSBSP260)This is a MITSUBISHI Electric spindle drive unit that permits a CNC Machine-tools drive a MITSUBISHI AC Spindle motor with a max output capacity of 26kW (97A rated output from the spindle drive unit).

MITSUBISHI Electric MDS-B-SP-260 Rated input :

DC270-311V : 97A

AC200-230V : 0.2A

MITSUBISHI Electric MDS-B-SP-260 Rated output : 3AC - 97A

In systems wich use a MITSUBISHI Electric MDS-B-SP-260 Spindle drive unit, the spindle drive unit must be placed next to the power supply as shown in the connection manuals. Each units generates some heat, so leave a space on the top and bottom when installing other equipment or parts. The heating value for the spindle drive unit for during continuous rated output (190W). Buy MITSUBISHI Spindle drive unit MDS-B-SP-260 online.

The power supply unit capacity is determined by the motor output, and the spindle drive unit capacity is determined by the motor characteristics
MDS-B-SP-150 CNC SPINDLE DRIVE UNIT 22KW from MITSUBISHI ELECTRIC.This MITSUBISHI ELECTRIC spindle drive MDS-B-SP-150 is ready to replace your spindle drive and to be mounted on CNC machine tools such as transfer machines, milling machines and turning machines.

MDS-B Series servo and spindle system outline
The MDS-A Series is a drive system that corresponds to the MELDAS M500 Series NC that has been developed to totally connected the servo drive and spindle drive sections. The MDS-B Series is the successor to the MDS-A Series, and has been developed to satisfy European Safety Standards. This Series has the following features.

Compact and lightweight

The converters that were conventionally built in each servo and spindle drive have been integrated into one unit. The drive system volume, installation area and weight have been drastically reduced with the incorporation of high density mounted electronic parts IGBT-IPM (intelligent Power Module) and the high performance heat radiating fin.

Standardization of dimensions

The outline has been standardized to the book end type, and by unifying the height and depth dimensions, installation in cabinets has been made easy. Furthermore, by matching the shape with the NC unit, an integrated appearance with the NC has been realized.

Low heat generation

By incorporating the IPM and using power supply regeneration in the servo drive, the amount of heat generated has been greatly reduced.

High speed and precision processing

A high speed CPU has been mounted on the control PCB, and a 100,000 pulse/rotation sub micron detector has been incorporated as a standard to allow faster and more precise interpolation.

By incorporating the stable position loop control (SHG control) method, having an outstanding response, the positioning time and tracking have been improved and the machine vibration during acceleration/deceleration has been reduced.

The cutting performance and cutting precision during position control have been improved by using the high speed CPU also for the spindle drive.

High speed spindle orientation

Smooth operations and minimum orientation times have been realized by using the high speed orientation method while allows direct orientation from the high speed during the spindle drive.

Features of the MDS-B Series

European Safety Standards compliant

This Series complies with the European Safety Standards (LVD). Refer to the section "Compliance to European EC Directives" for details.

Addition of power supply emergency stop input line

With the B Series, the external contactor can be directly shut off from the power supply even when the emergency stop hot line from the NC does not function for any reason.

(This function is validated with the rotary switch and connected drive parameter settings. Thus, the functions does not change from the conventional functions when used in the same manner as the A Series.)
