OVERVIEW

The MMC120 Motion Control Module is a complete two-axis position control subsystem for the Modicon TSX
Quantum Automation Series

family of Programmable Controllers. An onboard processor controls the axes,

providing complete independent PID motion control loops and allowing on-the-fly motion profile changes.
The module has two optically isolated magnetostrictive transducer interfaces and two optically isolated ±10
volt outputs.

The MMC120 occupies one slot of the Quantum rack. The MMC120 and the Programmable Controller
communicate over the backplane through four output and four input registers. The onboard 80C188EB
20MHz processor relieves the Programmable Controller of the overhead needed for servo control. The Motion
Control Module updates the axis position and drive output 1000 times each second, assuring precise
positioning even at high speeds.

If more than two axes of control are needed, additional MMC120 modules can be installed.
