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 Instructions for functional safety circuits This manual does not contain the complete safety instructions of the drive. It only includes the instructions related to the scope of this manual. Only a qualified electrical professional who has sufficient knowledge about functional, machine, and process safety is permitted to install, start up and maintain the safety circuit.
Safety instructions 9 Electrical safety precautions These electrical safety precautions are for all personnel who do work on the drive, motor cable or motor. WARNING! Obey these instructions. If you ignore them, injury or death, or damage to the equipment can occur. If you are not a qualified electrical professional, do not do installation or maintenance work.
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.
12 Introduction to the manual Quick reference guide for taking a safety function into use Task Connect the user-defined wiring (if any). See the wiring instructions in this manual and the circuit dia- grams delivered with the drive. Check and/or set the safety function related parameters (as listed in this manual). Do the validation test to make sure that the implemented system meets the safety requirements.
The main contactor/breaker of the drive is not opened. For option +Q964, ABB installs the FIO-01 digital I/O extension module (option +L501) to the drive control unit (Slot 1).
14 Option description For a complete list of related standards and European directives, see section Related standards and directives (page 33). Operation principle The figure shows a simplified operation principle. For a more detailed description, refer to the circuit diagrams delivered with the drive. 24 VDC+ -A62 -A62...
Option description 15 Step Operation Initial status: The drive is in operation and the motor is running. The user activates emergency stop with the emergency stop button [S61]. The emergency stop safety relay [A61] de-energizes the digital input on the digital I/O extension module [A412.X] of the drive.
16 Option description Hardware settings The time delay on the emergency stop safety relay [A61] is adjustable. Set the delay according to the application requirements. Make sure that the delay is slightly longer than the emergency stop deceleration time defined by drive parameters 23.23 Emergency stop time, and 46.01 Speed scaling or 46.02 Frequency scaling.
Note: The safety circuit design can be different when modified according to the customer's safety requirements. Refer to the circuit diagrams delivered with the drive. 3. Use shielded, twisted pair cables. ABB recommends double-shielded cable and gold-plated contacts in the emergency stop button.

You can also install additional reset buttons and indication lamps for the emergency stop circuit on site. ABB recommends gold-plated contacts in the reset button. Connect the buttons to the applicable terminal block inside the drive cabinet. Refer to the circuit diagrams delivered with the drive.
Parameter settings 19 Parameter settings Contents of this chapter This chapter contains the parameter settings related to the safety function. Drive parameter settings This section shows the drive parameter settings related to the safety function in the ACS880 primary control program. The table that follows shows the parameters that are set at the factory.
(STO) signals are switched off or lost. Warn- ing/Warning is the recommended setting. 1) Value set by ABB at the factory for the default design. The table that follows shows the parameters that you must set according to application requirements.
Use of the safety function 21 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 Activation procedure: 1. Push the emergency stop button [S61]. The emergency stop is activated and the button locks in the “ON”...
22 Use of the safety function Resetting the safety function WARNING! Make sure that the drive does not start accidentally. This can occur after the reset of the safety function, if a level-triggered start command and the start enable signal are on at the same time.
Start-up and validation test 23 Start-up and validation test Contents of this chapter This chapter describes the start-up, validation test procedure, and validation of the safety function. Validation of the safety functions You must do a validation test to validate the correct operation of safety functions. Competence ■...
24 Start-up and validation test Validation test reports ■ You must store the signed validation test reports in the logbook of the machine. The report must include, as required by the referred standards: • a description of the safety application (including a figure) •...

Start-up and validation test 25 Action Validation test ABB recommends 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 (%) •...
Fault tracing 27 Fault tracing Contents of this chapter This chapter provides general diagnostics and troubleshooting tips. Fault tracing The emergency stop safety relay [A61] type is DOLD UG 6960. This table gives the indications of the DOLD UG 6960 relay: Color LED is on LED is flashing...
LED is on Power supply is connected. Relay K1 energized. Power supply is connected. Relay K2 energized. 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 the wiring or a 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. • If parameters were restored to the factory default values: Set the parameters related to the safety function.
30 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 done at least every month.
■ This safety data is valid for the default design of the safety circuit described in this manual. If the final design is different from the default, ABB calculates new safety data and delivers it separately to the customer. The safety data calculations are based on the assumption that the emergency stop is used once a month.
