What is a servo press?

A servo press uses servo motors for precise force and position control during forming operations.

New Safety Standards for Servo Press Systems

admin

Safety standards for servo press systems have evolved significantly. Here is the current regulatory landscape.

## Key Standards

**ISO 16092-1:2017** — Machine tools safety: Presses. General requirements. Covers all press types including servo presses.

**ISO 16092-3:2017** — Specific requirements for mechanical presses including servo-driven presses. Covers stopping performance, brake monitoring, and speed/position monitoring.

**EN ISO 13849-1** — Safety-related parts of control systems. Servo press safety functions must achieve **Performance Level d (PLd) or e (PLe)**.

## Servo-Specific Safety Requirements

Standards now require:
- **Safe Torque Off (STO)** — IEC 61800-5-2 certified
- **Safe Stop 1 (SS1)** — controlled deceleration before STO
- **Safe Limited Speed (SLS)** — for setup and maintenance modes
- **Safe Position monitoring** — to prevent unexpected motion

## Recent Updates (2023-2024)

The 2023 revision introduced new requirements for:
- Collaborative robot integration with servo presses
- Power and force limiting in setup mode
- **Cybersecurity requirements** for networked press controls (compliance deadline: 2025)

## Practical Compliance Steps

1. Conduct formal risk assessment per ISO 12100
2. Verify safety function performance levels with certified safety engineer
3. Document all safety functions in the safety manual
4. Perform annual safety system validation testing
5. Ensure all operators receive documented safety training

CE compliance is a headache but necessary. We just went through it for a new Aida installation. The biggest cost wasn't the press itself —it was the light curtain and safety PLC integration. Budget an extra $25,000-40,000 for safety system integration on top of the press price.

ISO 16092-4 specifically for servo presses is worth reading carefully. The key difference from mechanical press standards is the requirement for safe torque off (STO) and safe stop 1 (SS1) functions in the drive. Most modern servo drives have these built in but they need to be properly configured and tested.
