Product description
The AX5801 Safety Card from Beckhoff is used to realize the safe stop functions "STO or SS1 according to IEC 61800-5-2". STO stands for SafeTorqueOff, SS1 for SafeStop1.
Thanks to the integrated two-channel monitoring of the AX5000, you can realize stop category 0 or 1 according to IEC 60204-1 with minimum effort and further TwinSAFE blocks from Beckhoff, thereby achieving category 4, PL e according to ISO 13849-1:2006.
Two-channel monitoring is achieved through certified relays (Rel1 and Rel2). The relays are equipped with positively driven contacts including feedback contacts (K1 and K2). The feedback contacts are connected in series and potential-free with terminals (5) and (6) of the 6-pin connector.
The two coils (S1 and S2) have to be supplied with 24 V DC via terminals 1 and 2 or 3 and 4 of the 6-pin or 4-pin connector. Terminals 1-1, 2-2, 3-3 and 4-4 of the two connectors are bridged internally. If a relay releases, the de-energizing circuit of the AX5000 servo drive range ensures that the connected motors (both channels) become torque-free.
