Mitsubishi Electric MELDAS MDS-B-SVJ2 Series - Power Supply Connection

Chapter 2 Wiring and Connection
2-21
2-5 Connection of power supply
CAUTION
1. Make sure that the power supply voltage is within the specified range of the
servo amplifier. Failure to observe this could lead to damage or faults.
2. For safety purposes, always install a circuit protector, and make sure that
the circuit is cut off when an error occurs or during inspections. Refer to
Chapter 7 and select the circuit protector.
3. The wire size will differ according to the amplifier capacity. Refer to Chapter
7 and select the size.
4. For safety purposes, always install a contactor (magnetic contactor) on the
main circuit power supply input. Large rush currents will flow when the
power is turned ON. Refer to Chapter 7 and select the correct contactor.
2-5-1 Example of connection when using converter unit
When there is a converter unit in the system, use the contactor control output (MC1) of the converter.
The MDS-C1-CV can directly drive the contactor.

Sharing of the circuit protector
is limited to when using a smal
capacity converter.
(Refer to "7-2 Selection of
circuit protectors".)
CAUTION
1. The MDS-C1-CV is a power supply regenerative type converter; an AC
reactor is required in the power supply line.
Connect the MDS-B-SVJ2 main circuit power supply on the power supply
side of the AC reactor.
2. A circuit protector and contactor cannot be shared when the rated current of
the circuit protector exceeds 60A.
