Schneider Electric TSXCAY21 Overview

The TSXCAY21 is a motion control module manufactured by Schneider Electric. It is designed for use with servomotors and serves as a controller for precise motion control applications. The module comes with a warranty period of 2 years, ensuring its reliability and performance. These products are manufactured in France and are designed for Material handling, packaging, and textile machines usage. They come with a 2-year warranty from MRO Electric. We also carry Controllers from other manufacturers such as Modicon and ABB.


In terms of power requirements, the TSXCAY21 has a current consumption of 200 mA at 5 V DC and 300 mA at 24 V DC. This ensures efficient power usage and compatibility with various power sources.


As a motion control module, the TSXCAY21 is responsible for controlling and monitoring servomotor movements. It incorporates a servo loop that utilizes proportional overshoot compensation and gains switching with a response time of 2 ms. This allows for accurate and precise control over the servomotors.


To ensure the proper functioning of the system, the TSXCAY21 performs various checks. These include checking the presence of voltage and sensor feedback, counting input signals, validating parameters, verifying the sensor power supply, executing movements correctly, checking encoder coupling, servo drive presence, and emergency stop functionality. These checks guarantee the reliability and safety of the motion control system.


The TSXCAY21 supports different speed profile paths, including trapezoidal and parabolic profiles. It also offers flexibility in terms of resolution, supporting position units per point of up to 1000 or greater than 0.5. This allows for precise control over the motion trajectory.

The module supports limited axis types and can be used as a follower or in automatic, direct drive, or manual operating modes. It also offers I/O modularity for up to 2 axes, providing flexibility in system configuration.


In terms of input compatibility, the TSXCAY21 supports various types of encoders, including absolute encoders with parallel output, 2-wire/3-wire sensors with 24 DC auxiliary inputs, and incremental encoders with different voltage specifications. This wide compatibility enables integration with a range of encoders commonly used in motion control applications.


The TSXCAY21 provides outputs for servo drive validation, reflex outputs, and analog outputs. These outputs offer flexibility for system integration and control. The module supports different voltage ranges, resolutions, and current limits to accommodate various application requirements.


For protection and safety, the TSXCAY21 includes features such as short-circuit protection, thermal tripping and reverse polarity protection. These features safeguard the module and connected devices from potential damage due to faults or incorrect connections.


The module includes LED indicators for diagnostics, internal and external fault indications, and operational status. These indicators assist in troubleshooting and monitoring the module's performance.


In terms of electrical connections, the TSXCAY21 utilizes various connectors, including SUB-D 15 for incremental or absolute encoders, SUB-D 9 for analog output, and HE-10 20-pin connectors for servo drive control inputs, auxiliary inputs, reflex outputs, and power supplies. These connectors provide a reliable and secure interface for connecting the module to other components in the motion control system.

Overall, the TSXCAY21 from Schneider Electric is a versatile motion control module that offers precise control, compatibility with various encoders, and a range of input and output options. Its robust design, reliability, and comprehensive set of features make it suitable for a wide range of motion control applications.
