13.5.3 Application 2
Fig.: 27: Application 2
The safety device(s) transmit(s) a +24 V signal for activating the digital servo
amplifier to the input Enable1 and Enable2 individually. At calling up the safety
function, both contacts open and thus block the enabling signal. In case of an error,
it is sufficient that at least one of those two contacts opens, in order to switch off the
motor safely (dual-channel switch-off). Deactivating the inputs leads to immediate
switching off the motor (Stop Category 0). By means of the wiring technology, a
short, both between the contacts of the emergency stop device, and between the two
lines, can be precluded.
As this application is not self-testing, proper function must be tested regularly. These
tests are to prove freedom from faults of the entire system.
Following this example, "Safe Standstill" (according to EN 954-1 Category 2) with
Stop Category 0 (according to EN 60204) can be set up, if all safety devices involved
also meet the requirements of Category 2.
