9.10 Commissioning
Staff members are forbidden to access the danger zone until the safety
functions have been validated.
Acceptance test
The scope of this section are the machine safety functions that use safety
functions of the drive. An example of this would be an SS1 function that is
demanded when the emergency button is pressed, and that in turn demands
the STO function from the drive. See EXAMPLE 2.
The acceptance test for the safety functions forms part of the machine
validation.
It is the machine designer's responsibility to meet the requirements of EN
ISO 13849-1 for the full validation of the parts related to the safety of the
machine control system.
The validation process is defined by EN ISO 13849-2.
Make sure to:
 Test for each safety function, that each channel executes the function
separately.
 Test the feedback for each channel of each safety function.
 Measure the response times of the safety functions of the machine. See
section RESPONSE TIME OF THE SAFETY FUNCTIONS OF THE MACHINE.
 Document the tests that have been performed.
Partial acceptance test
The machine already passed the acceptance test and was working
satisfactorily. A malfunction that requires the connectors to be unplugged
and/or the drive to be replaced makes it necessary to conduct a partial
acceptance test.
After repairing the malfunction, check that all the connectors
are plugged in
correctly and with the machine doors closed:
 Check that the motor turns satisfactorily in both directions.
 Press the emergency button to check STO and that the feed axis with
the brake does not drop.
 Check that the safety functions have been reset.
Validation of the conventional part of the drive
The · man_qc_60_65_inst.pdf · manual describes the start-up instructions
for the parts not related to functional safety.
