Motion Architecture and Control Capabilities

The TSXCAY21 uses a dedicated DSP processor for motion calculations. This processor generates step and direction signals for external drives. The Schneider TSXCAY21 controls one axis with 32-bit position resolution. It supports both stepper motors and servo drives with step/direction input. The module generates step frequencies up to 200 kHz for high-speed positioning. It provides trapezoidal or S-curve acceleration profiles for smooth motion.

Feedback and Registration Functions

This motion control module accepts incremental encoder feedback from RS-422 signals. The encoder input reads up to 200 kHz for precise position verification. The TSXCAY21 includes electronic gearing for slave axis synchronization. A registration input captures exact position at a sensor trigger. The module compares commanded and actual positions continuously. It generates a following error if the discrepancy exceeds programmed limits.

Inputs, Outputs, and Limit Handling

The Schneider TSXCAY21 features four dedicated 24 V DC digital inputs. These inputs connect to positive limit, negative limit, home, and general sensors. Four digital outputs provide 24 V DC signals for drive enable and brake control. The module automatically stops motion when a limit switch activates. It uses the home input to establish a machine reference position. Five status LEDs show power, running, communication, limit, and error status.

Physical Dimensions and Installation Guidelines

The Schneider TSXCAY21 weighs only 0.200 kilograms for lightweight mounting. Its height measures 103.7mm, width 33.5mm, and depth 118.5mm. Install this module in any Modicon Premium rack slot. The TSXCAY21 consumes 85 mA at 5 V DC and 120 mA at 24 V DC. It operates reliably from 0°C to +60°C ambient temperature. Use shielded twisted-pair cables for step/direction and encoder connections.

Energy Storage and Electrical Characteristics

The TSXCAY21 includes a 100 µF capacitor for power supply filtering. This capacitor stabilizes the internal 5 V and 24 V DC rails. It also protects against voltage dips during heavy motor acceleration. The Schneider TSXCAY21 requires no battery for normal motion control operation. It stores configuration parameters in non-volatile flash memory. You will never perform battery replacement on this motion module.
