General safety instructions and information on use The chapter "General safety instructions and information on use" contains general safety instructions for the Operator and the Operating Staff. At the beginning of certain main chapters, some safety in- structions are included which apply to all work described in the relevant chapter. Special work-specific safety instructions are provided before each safety-relevant work step.
Designated use The frequency inverter is designed according to the state of the art and recognized safety regulations. The frequency inverters are electrical drive components intended for installation in industrial plants or machines. Commissioning and start of operation is not allowed until it has been verified that the ma- chine meets the requirements of the EC Machinery Directive 2006/42/EC and DIN EN 60204-1.
Residual risks Residual risks are special hazards involved in handling of the frequency inverter which cannot be elim- inated despite the safety-compliant design of the device. Residual risks are not obviously identifiable and can be a potential source of injury or health hazard. Typical residual hazards include: Electrical hazard Danger of contact with energized components due to a defect, opened covers or enclosures or im-...

2.10.5.1 The five safety rules When working on/in electrical plants, always follow the five safety rules: 1. Isolate 2. Secure to prevent restarting 3. Check isolation 4. Earth and short-circuit, 5. Cover or shield neighboring live parts. 2.10.6 Safe operation •...
2.10.7 Maintenance and service/troubleshooting Visually inspect the frequency inverter when carrying out the required maintenance work and • inspections at the machine/plant. • Perform the maintenance work and inspections prescribed for the machine carefully, including the specifications on parts/equipment replacement. •...
Check the safety function at regular intervals according to the results of your risk assessment. BONFIGLIOLI VECTRON recommends that the check is performed after one year, at the latest.
Warning! Dangerous voltage! After disconnection of an external DC 24 V power supply, the DC link of the frequency inverter is still connected to mains supply. Even if the motor control is deactivated and the motor is coasting to a standstill or has already stopped, high voltages may still be present on the motor terminals.
Information of Risk Analysis and Risk Assessment According to the Directive on Machinery 98/37/EC, the manufacturer of a machine is obliged to carry out a risk analysis in order to identify the hazards related to the machine. The Standard EN 14121-1 – Safety of machinery - Risk assessment – Principles – describes the infor- mation required for risk assessment.
General Description of Safety Function Integrated Safety Function Electronic protection systems are integrated in the drive control system and perform safety functions in order to minimize or eliminate hazards caused by functional errors of machines. The integrated safety functions replace time-consuming and expensive installation of external safety components.
Description of ACTIVE Cube Safety Function The frequency inverters of the ACU series of devices feature the integrated safety function „Safe torque off, STO“. In the case of an error or if requested, the power semiconductors of the frequency inverter will be switched off.
Triggering of function “Safe Torque Off” Safe Torque Off can be achieved by: − Intentional triggering during operation in order to stop a drive and safely prevent restarting, e.g. for maintenance work on a machine. − Triggering by actuation of an emergency stop switch or monitoring of protective systems, e.g. safety door.

Stop paths Mains S1IND (STOA) S7IND (STOB) µC Diagnosis and monitoring Control unit Power unit The test required for monitoring is performed by the frequency inverter automatically. If the test re- sults negative, the frequency inverter cannot be switched on anymore. Starting is possible again only after the error has been repaired and the next test has been completed successfully.

Select the dimensions of the safety application such that 14 mA input current is available for each of the inputs STOA and STOB. If more than one ACTIVE Cube frequency inverters are connected to one safety control device, the safety control device must provide sufficient power for all of them.
External Safety Control Equipment Safety control equipment, upon request (e.g. actuation of emergency stop or access to hazard area, must trigger appropriate responses in order to protect people, the machine and the environment. They evaluate sensor signals or safely switch off dangerous states. External safety control devices must meet the following requirements: −...
DC 24 V Power supply by ACU You can use terminal X210A.1 in order to supply a safety control device. Only use the power supply for the device connected to the frequency inverter. Other safety control devices must not be con- nected.
Application Examples The following examples illustrate how the “Safe Torque Off” function works. According to EN 60204, stop functions are divided in different categories. By suitable safety control devices, stop categories 0 and 1 can be realized in combination with the frequency inverter ACU. Stop category 0: Stop by immediate disconnection of energy supply to the machine drive elements, i.e.
If the emergency stop device with two stop channels according to EN ISO 13849-1 PL d, IEC 61508 SIL 2 or EN954-1 Category 3 is actuated, both stop paths STOA and STOB of the ACTIVE Cube fre- quency inverter are interrupted and the integrated safety function with safe pulse block with SIL 2 according to EN-61800-5-2 is activated.
10.2 Direct Stop with Feedback to PLC, Stop Category 0 The application circuit shows a drive control system according to EN ISO 13849-1 PL d, IEC 61508 SIL 2 or EN 954-1 category 3 with PLC and safety module. A PLC performs the process control of the fre- quency inverter and can start the drive profiles via commands.
10.3 Direct Stop, Stop Category 1 The application example shows the minimum circuitry for ACTIVE cube frequency inverters for realiza- tion of the safety function STO “Safe Torque Off” with an emergency stop device in a common electri- cal cabinet.
10.4 Direct Stop with Feedback to PLC, Stop Category 1 The application circuit shows a drive control system according to EN ISO 13849-1 PL d, IEC 61508 SIL 2 or EN 954-1 category 3 with PLC and safety module. A PLC performs the process control of the fre- quency inverter and can start the drive profiles via commands.
Internal DC 24 V Supply, Stop Category 1 The application example shows the minimum circuitry for ACTIVE cube frequency inverters for realiza- tion of the safety function STO “Safe Torque Off” with an emergency stop switch in a common electri- cal cabinet.
10.6 Group Stop, Stop Category 1 The application circuit shows a drive control system according to EN ISO 13849-1 PL d, IEC 61508 SIL 2 or EN 954-1 category 3 with a PLC connected via the field bus and safety module. A PLC performs the process control of the frequency inverter and can start the drive profiles via commands which are communicated through the field bus.
10.7 Error exclusion “short circuit” in the cabinet The application circuit shows a drive control system according to EN ISO 13849 PL d, IEC 61508 SIL 2 or EN 954-1 category 3 with PLC and safety control equipment. Safety control equipment with one enable path and interconnection line is implemented instead of safety control equipment with two enable paths.
- SIL 2 (or smaller) according to IEC 61508 - Category 3 (or smaller) according to EN 954-1 − considers the stopping behavior of the ACTIVE Cube frequency inverter − permits coasting of the drive to a standstill or requires the installation of a mechanical brake.
