ABB ACS880-17 - Start-Up Including Acceptance Test

The Safe torque off function 205
4. The control program generates an indication as defined by parameter 31.22 (refer to
the firmware manual of the motor-side converter).
5. Motor coasts to a stop (if running). The drive cannot restart while the activation switch
or safety relay contacts are open. After the contacts close, a new start command is
required to start the drive.
Start-up including acceptance test
To ensure the safe operation of a safety function, validation is required. The final
assembler of the machine must validate the function by performing an acceptance test.
The acceptance test must be performed
• at initial start-up of the safety function
• after any changes related to the safety function (circuit boards, wiring, components,
settings, etc.)
• after any maintenance work related to the safety function.
 Competence
The acceptance test of the safety function must be carried out by a competent person with
adequate expertise and knowledge of the safety function as well as functional safety, as
required by IEC 61508-1 clause 6. The test procedures and report must be documented
and signed by this person.
 Acceptance test reports
Signed acceptance test reports must be stored in the logbook of the machine. The report
shall include documentation of start-up activities and test results, references to failure
reports and resolution of failures. Any new acceptance tests performed due to changes or
maintenance shall be logged into the logbook.
 Acceptance test procedure
After wiring the Safe torque off function, validate its operation as follows.
Note: If the drive is equipped with safety option +Q950, +Q951, +Q952, +Q957, +Q963,
+Q964, +Q978 or +Q979, do the procedure shown in the documentation of the option. If
the drive is equipped with safety option +Q972 or Q973, do the procedure shown in the
FSO module documentation. If an FSO-xx safety functions module or an FPTC-0x module
is installed, refer to its documentation.
Action
WARNING! Follow the safety instructions given in chapter Safety instructions (page 13). If
you ignore the instructions physical injury or death, or damage to the equipment can occur.
Ensure that the drive can be run and stopped freely during start-up.
Stop the drive (if running), switch the input power off and isolate the drive from the power line by a
disconnector.
Check the Safe torque off circuit connections against the wiring diagram.
Close the disconnector and switch the power on.
