Product Details

Modicon CGP31-R is a high-performance brushless servo motor and reliable motion drive motor designed for classic Modicon motion control systems. This legacy servo unit works together with matching servo drives to deliver precise speed, torque and closed-loop positioning for automated machinery. Equipped with an integrated high-resolution encoder, the brushless servo motor feeds real-time position data back to the drive, correcting positioning deviation continuously during operation. It adopts brushless construction to cut down wear and extend service life, making this motion drive motor a preferred replacement option when original motors fail. As a discontinued spare, this legacy servo unit helps ageing production equipment retain its original motion accuracy without redesigning the whole mechanical structure.

Supported Functions

This brushless servo motor supports closed-loop positioning, constant-speed running and adjustable torque output under drive command. The motion drive motor provides real-time encoder feedback for position tracking and error compensation. This legacy servo unit supports cyclic continuous operation and can execute homing, point-to-point movement and synchronous axis tasks for multi-axis automation equipment. It also sends fault signals when overload or stall conditions occur for rapid maintenance response.

Core Functions

As the core motion drive motor, this brushless servo motor converts electrical control signals into accurate rotary mechanical power. Its encoder maintains closed-loop feedback to guarantee positioning repeatability. This legacy servo unit serves as a direct drop-in replacement to restore precise motion performance for old Modicon automated control racks.
