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.

10 Safety instructions DC voltage charging due to leakage capacitances of the motor circuit. This voltage can remain charged for a long time after the drive power-off. The measurement discharges the voltage. • Make sure that the voltage between the drive DC terminals (UDC+ and UDC-) and the grounding (PE) terminal is zero.
This chapter also contains a quick reference guide for implementing a safety system. Applicability This manual is applicable to ACS580-07, ACH580-07 and ACQ580-07 drives which have the option: Emergency stop, stop category 0 with STO, with safety relays (option +Q963).
12 Introduction to the manual 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 15 Option description Contents of this chapter This chapter describes the +Q963 emergency stop option and its settings. Overview Option +Q963 corresponds to an uncontrolled stop in accordance with stop category 0 (IEC/EN 60204-1). When the user gives the emergency stop command, the drive activates the Safe torque off (STO) function.
Option description 17 Fault reaction function Definition: A safety function requires a “fault reaction function” that tries to initiate a safe state if it detects a failure in the safety system. The fault reaction function of the emergency stop safety relay trips the system, if it detects a failure in the safety circuit (for example, short circuit between signals, open circuit, or redundancy fault).
Electrical installation 19 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. Wiring WARNING! Obey the safety instructions of the drive. If you ignore them, injury or death, or damage to the equipment can occur.

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.
Name Description Default value 31.22 STO indication Warning/Warning Selects which indications are given when the Safe torque run/stop off (STO) function is activated. Warning/Warning is the recommended setting. 1) Value set by ABB at the factory for the default design.
Use of the safety function 23 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: Push the emergency stop button [S61]. The emergency stop is activated and the button locks in the “ON”...

24 Use of the safety function Make sure that the drive receives the start signal. You can now restart the drive. For more information, refer to the hardware and firmware manuals.
Start-up and validation test 25 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 make sure that the safety function operates correctly and according to the safety requirements.
26 Start-up and validation test The validation test must include at least the following steps: • you must have a validation test plan • you must test all commissioned functions for correct operation, from each operation location • you must document all validation tests •...

Make sure that the parameter settings related to the safety functions are correct. Refer to chapter Parameter settings. Validation test ABB recommends that you monitor at least 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) •...
Fault tracing 29 Fault tracing Contents of this chapter This chapter provides general diagnostics and troubleshooting tips. Fault tracing The emergency stop safety relay [A61] type is Phoenix Contact PSR-MC34. This table gives the indications of the Phoenix Contact PSR-MC34 relay: PWR LED IN1/2 LED K1 LED...
30 Fault tracing For more fault tracing possibilities, refer to 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, replace a power unit or its circuit boards, 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.
The remaining mission time of the whole circuit is however determined by its oldest component. Contact your local ABB service representative for more information. Competence The person who does the maintenance and proof test activities of the safety function must be a competent person with expertise and knowledge of the safety function and functional safety, as required by IEC 61508-1 clause 6.
Maintenance 33 Decommissioning When you decommission an emergency stop circuit or a drive, make sure that the functional safety of the machine is maintained by other means until the decommissioning is completed.
The 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 and the customer has ordered safety data calculations (option +P947), ABB calculates new safety data and delivers it separately to the customer.
