IEC 60204-1:2021: Safety of machinery - Electrical equipment of machines - Part 1: General requirements

1. Power Supply and Protection

• Servo drives must be supplied within the rated voltage and frequency limits defined in the standard (≤1000 V AC or ≤1500 V DC).
• Overcurrent, short-circuit, and overvoltage protection must be provided.
• Protective bonding/grounding conductors are required to ensure safety against electric shock.

2. Protection Against Electric Shock

• Live parts of servo drives and motors must be enclosed or insulated.
• Protective extra-low voltage (PELV, typically ≤50 V AC or 120 V DC) should be used for control circuits where operator access is possible.

3. Control Circuits and Functions

• Servo systems must integrate with the machine’s emergency stop (E-stop) system; E-stop must override all motion.
• Prevention of unexpected start-up: servo drives must not energize motors automatically after power restoration unless explicitly intended.
• Enable devices, interlocks, and functional stop categories (Stop 0, Stop 1, Stop 2) must be considered in drive control design.

4. Wiring and EMC

• Motor and feedback cables must be routed and shielded to minimize electromagnetic interference (EMC).
• Separation of power cables and control/signal cables is recommended.
• Cables must be mechanically protected against stress, bending, or vibration.

5. Drive and Motor Components

• Servo drives and motors must comply with thermal protection requirements (overheating prevention).
• Proper selection of circuit breakers or fuses for servo drives according to manufacturer’s data.
• Components must be marked with identification consistent with circuit diagrams.

6. Functional Safety Integration

• Where servo drives perform safety-related functions (e.g., safe torque off, safe stop, speed monitoring), they must comply with IEC 61508 / IEC 61800-5-2 in addition to IEC 60204-1.
• Safety functions must be clearly documented and tested.

7. Documentation and Marking

• Electrical diagrams must show servo drives, feedback loops, protective devices, and control functions.
• Cables, terminals, and devices must be identified with durable markings.
• Manuals must include installation, maintenance, and safety information for the servo system.

8. Verification and Testing

• Insulation resistance and protective bonding continuity tests must be performed on servo drive systems.
• Verification of correct stop functions (including E-stop integration).
• EMC compliance tests where required.

IEC 61010-1:2017: Safety requirements for electrical equipment for measurement, control, and laboratory use - Part 1: General requirements

1. Scope and Basic Principles

• Applies to electrical equipment for measurement, control, and laboratory use, rated up to 1000 V AC or 1500 V DC.
• Covers stand-alone instruments, modular devices, and cabinet systems.
• Defines safety-related terms and application conditions.

2. Fundamental Protection

• Aims to protect against electric shock, fire, mechanical hazards, radiation, and chemical risks.
• Equipment must remain safe both in normal operation and under single-fault conditions.

3. Protection Against Electric Shock

• Requires protection from direct and indirect contact.
• Protective methods: insulation, grounding (protective earthing), isolation, and enclosures.
• Specific requirements for hand-held equipment, test probes, connectors, and terminals.

4. Insulation and Spacings

• Specifies minimum clearances, creepage distances, and solid insulation.
• Requirements vary by pollution degree (1–3) and overvoltage category (I–IV).

5. Overcurrent and Overtemperature Protection

• Mandatory use of protective devices (fuses, circuit breakers, PTCs, etc.).
• Limits for temperature rise of accessible surfaces and internal parts.
• Prevents fire hazards from abnormal heating or overloads.

6. Mechanical Hazards

• Protection against moving parts, rotating shafts, sharp edges, and crushing points.
• Enclosures must provide sufficient mechanical strength and stability.

7. Radiation and Chemical Hazards

• Limits for exposure to laser, UV, X-ray, acoustic energy and other emissions.
• Measures against risks from hazardous substances (toxic, flammable, or corrosive materials).

8. Marking and Documentation

• Equipment must have clear labels for ratings, warnings, and terminal identification.
• Documentation must include installation, operation, maintenance, and calibration instructions, with safety information.

9. Testing and Verification

• Type tests required, including:
• Dielectric strength (hipot) test
• Insulation resistance test
• Leakage current measurement
• Temperature rise test
• Mechanical strength test
• Verification of fire and radiation safety
• Ensures safety under worst-case conditions.
