The MITSUBISHI ELECTRIC manual number is BNP-B3937. This MITSUBISHI ELECTRIC MDS-B-SVJ2-20 servo drive unit is ready to replace your defective drive and comes with a warranty.
Higher servo gain addresses the first three issues. Higher servo gain in MITSUBISHI ELECTRIC model MDS was achieved by a combination of hardware and software improvements, along with shorter lag times for each of the control loops that help improves suppression of mechanical resonances.

Features of MDS-B-SVJ2

The MDS-B-SVJ2 Series servo drive unit is for NC,which was developed as the successor model to the MDS-A-SVJ Series. It has such features as below compared with SVJ.

1. CE Marking compliant (Compliant to European Safety Standard)

2. Installation convertibility with all the capacities of the SVJ series

3. New model, HC motor supported

4. 100,000 pulse ENC supported (OSA104,OSE104)

5. Standard regenerative resistor is integrated in drive unit (All capacities other than 100W)

6. Possible to integrate the battery for the absolute positioning system (MR-BAT) in drive unit (Battery unit is also possible to use.

7. By wiring the control power supply separately, possible to break the power supply for the main circuit by contactor

8. New functions added (External observer, overshoot compensation, adoptive filter, etc)

9. Motor brake and contactor control sequence output (DO output)

The MDS-B-SVJ2-01 does not have a built-in regenerative resistor. If the load inertia is small, there will be no problem with the capacitor regeneration (regenerative resistance is not required as the circuit is charged with the capacitor in the amplifier). However, the over voltage alarm (ALM33) will occur if the load inertia is large. In this case, connect the external option regenerative resistor.

When driving contactors with the MDS-B-SVJ2-01, always externally install a regenerative resistor. If there is no regenerative resistor installed, the contactor fusion alarm will be incorrectly detected.

General Precaution It takes 10 minutes to discharge the bus capacitor. (The capacitor discharge time is one minute for MDS-B-SVJ2-01, 03, 04; two minutes for MDS-B-SVJ2-06 and three minutes for MDS-B-SVJ2-07, 10, 20.) When starting wiring or inspection, shut the power off and wait for more than 15 minutes to avoid a hazard of electrical shock.

Installation MDS-B-SVJ2, MDS-B-SPJ2 and MR-J2-CT Series have been approved as the products which have been installed in the electrical enclosure. The minimum enclosure size is based on 150 percent of each MDS-B-SVJ2, SPJ2 and MR-J2-CT Series combination. And also, design the enclosure so that the ambient temperature in the enclosure is 55°C (131°F) or less, refer to the specifications manual. (MDS-B-SVJ2: BNP-B3937, MDS-B-SPJ2: BNP-B2164, MR-J2-CT: BNP-B3944) "The user must include the use of a 100 cfm fan spaced 4 in. above the drive."
