    Safety instructions 7 Safety instructions Contents of this chapter This chapter contains the safety instructions which you must obey when you install, operate and do maintenance on the safety functions of a drive. Use of warnings and notes Warnings tell you about conditions which can cause injury or death, or damage to the equipment.

  • Page 8: Electrical Safety Precautions

    8 Safety instructions Only a qualified electrician who has appropriate knowledge on functional, machine, and process safety is allowed to install, start up and maintain the safety circuit. All user-made changes are on the user's responsibility. WARNING! This safety function does not disconnect the voltage of the main and auxiliary circuits from the drive.
  • Page 9 Safety instructions 9 • Make sure that the voltage between the drive output terminals (T1/U, T2/V, T3/W) and the grounding (PE) busbar is close to 0 V. 6. Ask the person in control of the electrical installation work for a permit to work.

  • Page 11: Introduction To The Manual

    Applicability The manual applies to ACS880-07/17/17LC/37/37LC drives which have the option +Q965: Safely-limited speed with the encoder interface. For the option +Q965, ABB installs the FSO-21 safety functions module (option +Q972) and the FSE-31 pulse encoder interface module (option +L521) to the drive.

Classification of the safety-related parts of a control system in respect of their resistance to faults and their subsequent behavior in the fault condition, and which is achieved by the structural arrangement of the parts, fault detection and/or by their reliability. The categories are: B, 1, 2, 3 and 4.

  • Page 15: Option Description

    The option +Q965 requires that the FSO-21 safety functions module(s) (option +Q972) and the FSE-31 pulse encoder interface module(s) (option +L521) are installed in the drive. ABB installs the FSO and FSE-31 modules to the drive and sets the delivery configuration for the cabinet safety option at the factory.

  • Page 16: Summary Of Wirings And Setting

    The digital output of the FSO module to which the SLS indication signal is connected, is selected as the output for the SLS output. This is an FSO module parameter that ABB sets at the factory by default and the user must check at the start-up.

  • Page 17: Operation Principle

    SLS function except that it can only be configured to be continuously on or off. ABB activates the SMS function (Version 1) at the factory. This is an FSO module parameter that the user must check/set at the start-up.

  • Page 18: Sls With Speed Below The Monitored Speed

    18 Option description the SSE function activates the drive Safe torque off (STO) function either immediately or after a deceleration ramp. The motor coasts to a stop or decelerates to zero speed. There are four separate SLS functions in the FSO module with different parameter settings. The SLS1 function is used as an example and in the delivered default settings of the +Q965 option.

  • Page 19: Sls With Speed Above The Monitored Speed - Time Monitoring

    Option description 19 3. The user or a PLC deactivates the SLS request of the FSO module, that is, switches the digital input of the FSO module from 0 to 1. The FSO module acknowledges the SLS1 function automatically. This is set to be automatic by an FSO parameter (SLSx.02), and no external acknowledgement input is in use.

  • Page 20: Sls With Speed Above The Monitored Speed - Ramp Monitoring

    20 Option description (3b) Time B has elapsed. The FSO module starts SLS monitoring (if not already started). Note: If the motor speed is above the SLS monitoring limit after time B has elapsed, the FSO module activates the SSE function. Depending on SSE function parameter settings, the motor either coasts to a stop (“Immediate STO”) or ramps down to zero speed (“Emergency ramp”).

Obey the instructions of the encoder manufacturer as well as the following rules: •...

  • Page 48: Sls Function

    Note: If you change the input and the parameter settings in the FSO module into a one-channel implementation, it affects the safety integrity of the safety function. The safety data that ABB has calculated for the function is not valid. 2. Use a shielded, twisted pair cable. We recommend a double-shielded cable.

  • Page 49: Use Of The Safety Function

    Use of the safety function 49 Use of the safety function Contents of this chapter This chapter describes the use of the safety function with factory default settings. Activating and deactivating the SLS function To activate the SLS function, de-energize (24 V -> 0 V) the appropriate digital input of the FSO module.

  • Page 50: Activating And Deactivating The Ssm Function

    50 Use of the safety function • the FSO module generates a fault (see parameter FSOGEN.62) • the drive generates an event according to parameter 31.22 STO indication run/stop (see section Parameter settings). The indications that the FSO module generates are configurable. For more information, see section Parameter settings and chapter Fault tracing in FSO module user’s manual.

  • Page 51: Start-Up And Acceptance Test

    Start-up and acceptance test 51 Start-up and acceptance test Contents of this chapter This chapter describes the start-up, acceptance test procedure, and validation of the safety function. Validation of the safety functions You must do an acceptance test (validation) to validate the correct operation of safety functions.

  • Page 52: Acceptance Test Reports

    Note: The SLS acceptance test procedure described in this chapter does not test the trip limits, because the SLS function limits the motor reference speed to the SLS limit. ABB has validated the functionality of trip limits in the verification tests.
  • Page 53 Start-up and acceptance test 53 Action WARNING! Obey the safety instructions. If you ignore them, injury or death, or damage to the equipment can occur. Checks and settings with no voltage connected Stop the drive and do the steps in section Electrical safety precautions (page 8) before you start the work.
  • Page 54 54 Start-up and acceptance test Action Start the drive and make sure that the motor is running. For SLS function: Increase the motor speed close to the maximum speed of the application (above the SLS limit). For SMS function: Increase the motor speed above the speed defined in parameter SMS trip limit pos- itive.

  • Page 55: Maintenance

    If you change any wiring or component after the start-up, replace the FSO or FSE-31 module, modify FSO module parameters, or restore parameters to their factory default values: • Use only ABB-approved spare parts. • Register the change to the change log for the safety circuit.

  • Page 56: Competence

    56 Maintenance The person responsible for the design of the complete safety system should also note the Recommendation of Use CNB/M/11.050 published by the European co-ordination of Notified Bodies for Machinery concerning dual-channel safety-related systems with electromechanical outputs: • When the safety integrity requirement for the safety function is SIL 3 or PL e (cat. 3 or 4), the proof test for the function must be performed at least every month.
