Frequently Asked Questions about 20-750-S
Question: How does the Safe Torque Off (STO) feature work in the 20-750-S module?
Date Update:02/06/2025
Answer:

The STO feature in the 20-750-S module disables the drive’s output power devices, ensuring that no torque is produced at the motor shaft. This is achieved without completely shutting down the drive, which means the system can be quickly restarted after maintenance. The STO functionality provides a reliable method of de-energizing the motor in case of an emergency. It also helps meet international safety regulations such as SIL 3 (IEC 61508) and PLe (ISO 13849-1). This functionality ensures the protection of both personnel and equipment during maintenance operations.

Question: What are the input voltage and current specifications for the 20-750-S module
Date Update:02/06/2025
Answer:

The 20-750-S operates at a 24 VDC input voltage, which is standard for many industrial control systems. This allows for easy integration into existing safety circuits. The module supports a maximum current of 90 Amps, enabling it to handle significant loads while maintaining safety compliance. This combination of voltage and current ratings ensures reliable operation in a variety of applications. It also supports the quick de-energizing of the drive’s output power devices to achieve the STO function.

Question: How is the 20-750-S module installed in a system?
Date Update:02/06/2025
Answer:

The module can be installed using a DIN rail or panel mounting, depending on the available space and enclosure configuration. This flexibility allows for easy integration into new and existing drive systems. It is designed specifically to interface with PowerFlex 750-Series drives, ensuring mechanical and electrical compatibility. Proper installation ensures that the STO feature can be easily accessed and triggered when necessary.

Question: What are some key benefits of integrating the 20-750-S module in a drive system?
Date Update:02/06/2025
Answer:
  • Provides a reliable Safe Torque Off feature that enhances worker safety during maintenance.
  • Complies with international safety standards, including SIL 3 and PLe, ensuring high levels of safety integrity.
  • Offers easy integration with PowerFlex 750-Series drives, reducing installation complexity.
  • Supports diagnostics to aid in troubleshooting and system monitoring.
Question: Is the 20-750-S module still in production?
Date Update:02/06/2025
Answer:

Yes, the 20-750-S Safe Torque Off (STO) option module is currently active and available for purchase. This means it remains fully supported by Rockwell Automation and can be integrated into new or existing systems without concerns about obsolescence. It continues to be a best-selling safety module designed for the PowerFlex 750-Series AC drives.
