Parker Hannifin S.p.A. Divisione S.B.C. user’s manual TWIN-N and SPD-N
189
17.6 Example
The following diagram shows an example of safety disable and it is a general reference. Every
specific configuration of the machine must be verified in relation to the application.
17.7 Test and maintenance
The user must carry out a periodical functional test for the whole safety systems of the
machine/application. The functionality must specifically be verified at commissioning, after
any kind of maintenance operation on the machine (wiring, replacement of parts etc...) and
before any potentially dangerous circumstance for personnel (need to access machine
dangerous zones).
It must be verified that, using the safe disable function on each single drive unit, it is
impossible to move/rotate all the motors included in the machine safety system, and that this
safe standstill state is correctly detected through the feedback system from the drive unit (both
hardware feedback SC-A/SC-B and software feedback b90.6).
