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.
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! Always test the operation of the safety circuit according to its acceptance test procedure at the start-up and after any changes to the safety circuit.
Exclusion of liability ABB is not responsible for the implementation, verification and validation of the overall safety system. It is the responsibility of the system integrator (or other party) who is responsible for the overall system and system safety.

Option description 13 Option description Contents of this chapter This chapter describes the +Q951 emergency stop option and its settings. Overview Option +Q951 corresponds to an uncontrolled stop in accordance with stop category 0 (EN/IEC 60204-1). After the emergency stop command has been given, the drive trips the main contactor/breaker which cuts off the input power of the drive.
Note: Resetting the safety function is not possible, if the reset circuit in the emergency stop safety relay is open. Parameter settings Note: ACS880 primary control program controls the inverter unit by default. There are dedicated control units for the supply and inverter units. The inverter unit parameter settings in ACS880 primary control program: •...
16 Option description • parameter 31.22 STO indication run/stop is set to value Warning/Warning (recommended). The supply unit parameter settings in the ACS880 supply control programs: • parameter 121.04 Emergency stop mode is set to value Stop and warning •...
Electrical installation 17 Electrical installation Contents of this chapter This chapter describes the wiring of the safety option done at the factory and contains guidelines for making user connections (if any). Wiring If option +G331 has been selected, one emergency stop button and one reset button are installed on the cabinet door and wired to the drive at the factory.
■ Customer-installed main breaker in liquid-cooled ACS880 multidrives Liquid-cooled ACS880 multidrives can be delivered without a factory-installed main breaker. In these cases, customer must install and connect the main breaker to the safety circuit as described in the circuit diagrams.
Use of the safety function 19 Use of the safety function Contents of this chapter This chapter describes the use of the safety function with factory default settings. Activating the safety function 1. Push the emergency stop button [S61]. The emergency stop is activated and the button locks in the “ON”...
Start-up and acceptance test 21 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.
Check the parameters that are relevant to the safety function. If necessary, set the parameters as defined in section Parameter settings. Note: ACS880 primary control program controls the inverter unit by default. There are dedicated control units for the supply and inverter units.

Start-up and acceptance test 23 Action We recommend that you monitor these signals with the Drive composer PC tool: • 01.01 Motor speed used (rpm) • 01.02 Motor speed estimated (rpm) • 01.07 Motor current (A) • 01.10 Motor torque (%) •...
If the emergency stop safety relay cannot be reset, check the reset circuit connections. For more fault tracing possibilities, see the hardware and firmware manuals of the drive. Reporting problems and failures related to safety functions Contact ABB.
If you change any wiring or component after the start-up 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. •...
28 Maintenance (high or low demand as defined in IEC 61508, EN/IEC 62061 and EN ISO 13849-1). Regardless of the mode of operation, it is a good practice to check the operation of the safety function at least once a year by doing the start-up and acceptance test of the safety function.
