2.1 General description
AX5801 – TwinSAFE drive option card for the AX5000 servo drive series
The AX5801 TwinSAFE drive option card is an optional extension of the Beckhoff AX5000 servo drive
series. The following safety functions can be implemented by the installation of the AX5801 in the
AX5000:
•
Stop functions (STO, SS1)
The time delay for the SS1 function must take place in the higher-level safety controller.
The AX5801 drive option card has two relays (Rel1 and Rel2). The relays are equipped with positively
driven contacts including feedback contacts (K1 and K2). These feedback contacts are connected in
series and also have a potential-free connection to pins (5) and (6) of the six-pin plug. The NO contacts of
the two relays are connected in series and switch the AX5000 on two-channels according to STO.
The two coils (S1 and S2) must be supplied with 24 V DC via pins 1 and 2 or 3 and 4 of the six-pin or
four-pin plug. Terminals1-1, 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) are switched torque-free.
