Motor control system for controlling the operations of a plurality of servo motors

A motor control system comprising:

• main circuit power source means for converting AC power supplied from a power source into DC power;
• motor drive means for converting said DC power into AC power, and supplying said AC power thus converted to a plurality of servomotors, said motor drive means being in correspondence in number to said servomotor;
• control means for controlling the operation of said motor drive means,
• functional element units which are classified into a main circuit power unit including said main circuit power means, motor driving inverter units which includes said motor drive means, and which are accommodated in one and the same casing for every at least two of said plurality of servomotors, and a control unit for generally controlling said motor drive means, said units being accommodated in respective casings, and having electrical wiring unit-side connectors;
• and
• a circuit board on which a wiring circuit required for connecting said units to one another have been formed, and which has base-board side connectors which are engageable with said unit-side connectors,
• wherein when said functional element units being fixedly mounted on said circuit board as required, said unit-side connectors are engaged with said base-board side connectors, so that said functional element units are electrically connected to one another through said circuit board, thus forming said motor control system.
