Connection Example When Controlling The Electromagnetic Switch With The Mds-B-Cv/Cr; Output Circuit Of The Electromagnetic Switch Control Signal (Mcon∗) - Mitsubishi Electric MDS-B-SPJ2 Series Specification Manual

5.4.3 Connection example when controlling the electromagnetic switch
with the MDS-B-CV/CR
The following is a connection example when there is a convertor unit MDS-B-CV/CR is the system.
The electromagnetic switch control signal (MC1) of the MDS-B-CV/CR can directly drive the
electromagnetic switch.

• Refer to the "MDS-B Series Specification Manual BNP-B3759" for details about the convertor unit
MDS-B-CV/CR.
Always install a convertor unit AC reactor MDS-B-AL. Always wire the MSD-B-SPJ2 main circuit (L1,
L2, L3), control power (L11, L21) and spindle amplifier, etc., control power (L11, L21) to the primary
side of the MDS-B-AL.
5.4.4 Output circuit of the electromagnetic switch control signal (MCON∗)
A relay or photocoupler can be driven.
Install a diode for inductive loads.
