5.2.1 General information on acceptance
Why is acceptance required?
The EU machinery directive and ISO 13849-1 stipulate:
● You must test safety-relevant functions and machine parts after commissioning.
See "Acceptance test" below in this section.
For the F-TM ServoDrive Safety Integrated functions (SI functions), this means:
The acceptance test is used to check the functionality of the safety functions used in the
drive. Correct implementation of the defined safety functions is examined for this.
● You must create an "acceptance report" that describes the test results.
See "Documentation" further on in this section.
Note
Purpose of the acceptance test
The measured values (e.g. speed, time) and the system behavior identified (e.g. initiation of
a specif
ic stop) serve to check the plausibility of the configured safety functions. The
objective of an acceptance test is to identify potential configuration errors and/or to
document the correct function of the configuration. The measured values are typical val
ues
worst case values). They represent the behavior of the machine at the time of
measurement. These measurements cannot serve as the basis for deriving real values (e.g.
maximum values for over
-travel distances).
Requirements
The requirements for an acceptance test (configuration test) for safety functions of electric
drives come from EN 61800-5-2, section 7.1, paragraph f). The acceptance test is called
"configuration test" in this standard.
● Description of the application including an image
● Description of the safety-related components (including software versions) that are used
in the application
● List of the utilized safety functions of the PDS(SR) [Power Drive System(Safety Related)]
● Results of all tests of these safety functions using the specified test procedure
Necessity of an acceptance test
An acceptance test is required (again) when the Safety Integrated functionality of a machine
is commissioned or changed. The acceptance tests must be performed for each individual
drive. Safety-related function extensions, transfer of commissioning to other series
machines, hardware changes, software upgrades and the like may allow a partial
performance test to be performed.
The conditions determining the necessity and recommendations for the test depth required in
each case are summarized below.
