Overview

The 57652 is a dedicated Universal Drive Controller module for Reliance Electric AutoMax PLCs or specialized drive systems. It executes high-speed control loops for velocity, current, and coordinated motion, offloading low-level, time-critical tasks from the main PLC CPU. By managing real-time motor drive operations, it ensures precise dynamic performance and reliable operation of DC, AC, or servo drives.

Technical Data: High-Speed Control and Interface

Typical Applications

The 57652 was used in industrial applications requiring tight synchronization and dynamic response of motor drives, including:

• Tension control in web processing (film, paper)

• Flying cutoff and material positioning systems

• Coordinated multi-axis motion control in manufacturing lines

It provided the dedicated processing power necessary to execute complex, real-time drive operations and ensure high-quality, synchronized motion.

FAQ

Q1: What does 'Universal' imply for this drive controller module?
A: It means the module can be configured via software for various drive types—DC, AC inverter, or servo—using standardized control loops programmed in AutoMax.

Q2: Does the 57652 replace the main PLC CPU?
A: No, it acts as a coprocessor. The main CPU manages high-level sequencing, while the 57652 handles fast, real-time motor control tasks.

Q3: Is the 57652 module considered obsolete?
A: Yes, as part of the legacy Reliance Electric AutoMax system, it is no longer manufactured. Maintenance relies on surplus parts or specialized repair vendors.

Q4: How does the 57652 connect to motor feedback devices?
A: It includes dedicated inputs for high-speed feedback from encoders or resolvers, providing real-time position and velocity data for precise control loop closure.
