dation must have been successfully completed. To meet the requirements of
any application, the axis may be validated in four ways:
●
Drive-internal command value provision and drive-internal enable
● Drive-internal command value provision and external drive enable
● External command value provision and external drive enable
● Manual movement
8.4.3 Machine acceptance
From the drive’s point of view, accepting a machine is required whenever the
safety technology of a self-contained servo-hydraulic linear axis is parameter‐
ized for the first time (initial commissioning) or is modified.
Definition of “modified": Safety technology parameters were
changed or extended serial commissioning was carried out (copy
of a self-contained servo-hydraulic linear axis as template with
new axis identifier and different parameterization).
In the application of the safety functions of a self-contained servo-hydraulic
linear axis it is not sufficient to carry out acceptances according to the above
documentation. In the following the deviations/extensions are described,
which are relevant for the machine acceptance and illustrate the specific in‐
terrelationships in a self-contained servo-hydraulic linear axis with safety
functions.
Selection For the accepting the selection the description according to the documenta‐
tion above may be applied without any restrictions.
Global monitoring functions If global monitoring functions are activated, they can be accepted according
to the documentation mentioned above.
Please note that the monitoring functions refer to the externally
connected, safety-capable linear encoder, since it provides the
feedback in the case of a hazardous situation of the self-con‐
tained servo-hydraulic linear axis.
The following checks must be carried out, if the monitoring functions are acti‐
vated:
●
Check the safe maximum linear velocity
● Check the linear velocity threshold for "safe standstill"
Monitoring during normal opera‐
tion
If monitoring functions are activated during normal operation, they can be ac‐
cepted according to the documentation mentioned above.
Please note that the monitoring functions refer to the externally
connected, safety-capable linear encoder, since it provides the
feedback in the case of a hazardous situation of the self-con‐
tained servo-hydraulic linear axis.
Special mode "EMERGENCY
STOP" and “Safe standstill"
The special mode "EMERGENCY STOP" and “Safe standstill” can be accep‐
ted according to the above documentation.
Please note that the monitoring functions refer to the externally
connected, safety-capable linear encoder, since it provides the
feedback in the case of a hazardous situation of the self-con‐
tained servo-hydraulic linear axis.
