ABB ACS800-U1 - Acceptance Test Reports; Acceptance Test Procedure

30 Start-up and use
 Acceptance test reports
You must store the signed acceptance test reports in the logbook of the machine. The
report must include, as required by the referred standards:
• description of the safety application (including a figure)
• a description and revisions of safety components that are used in the safety
application (STO and other components)
• a list of all safety functions using STO that are used in the safety application
• a list of all safety related parameters and their values (STO has no safety-related
parameters)
• documentation of start-up activities, references to failure reports and resolution of
failures
• the test results for each safety function, checksums (not relevant for the STO safety
component), date of the tests and confirmation by the test personnel.
You must store any new acceptance tests performed due to changes or maintenance in
the logbook of the machine.
 Acceptance test procedure
After wiring the Safe torque off function, validate its operation as follows.
Action
WARNING! Obey the safety instructions given in the relevant hardware manual and ACS800
Multidrive and Multidrive modules Safety Instructions (3AFE64760432 [English]). If you
ignore them, it can cause physical injury or death, or damage to the equipment.
Ensure that the drive/inverter can be run and stopped freely during start-up.
Stop the drive/inverter (if running), switch the input power off and isolate the drive/inverter 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.
Test the operation of the STO function when the motor is stopped.
• Give a stop command for the drive/inverter (if running) and wait until the motor shaft is at a
standstill.
Ensure that the drive/inverter operates as follows:
• Open the STO circuit. The drive/inverter generates a "START INHIBI" warning.
• Give a start command to verify that the STO function blocks the operation of the drive/inverter. The
motor should not start.
• Close the STO circuit.
• Reset any active faults. Restart the drive/inverter and check that the motor runs normally.
Test the operation of the STO function when the motor is running.
• Start the drive/inverter and ensure the motor is running.
• Open the STO circuit. The motor should stop. The drive/inverter generates a "START INHIBI" fault.
• Reset any active faults and try to start the drive/inverter.
• Ensure that the motor stays at a standstill and the drive/inverter operates as described above in
testing the operation when the motor is stopped.
• Close the STO circuit.
• Reset any active faults. Restart the drive/inverter and check that the motor runs normally.
Document and sign the acceptance test report which verifies that the safety function is safe and
accepted for operation.
