Compax3 device description
192-120100 N16 C3I10T10 - December 2010
3.10.2.4 STO application example (= safe torque off)
In this chapter you can read about:
..................................................................................................... 83
The application example described here corresponds to Stop Category 1 as
defined by EN60204-1.
Together with the external safety switching device, the "Safe Stop 1ā(SS1) safety
function can also be implemented.
A Stop Category 0 in accordance with EN 60204-1 can be implemented, for
example by setting the delay time on the Emergency power-off module as well as
on the Compax3 (delay time for āswitch to currentlessā) to 0. The Compax3M will
then be turned off immediately in 2 channels and will therefore not be able to
generate any more torque. Please take into consideration that the motor will not
brake and a coasting down of the motor may result in hazards. If this is the case,
the STO function in stop category 0 is not permitted.
Circuit layout overview
ļµ 2 Compax3 devices (the circuit example is also valid for one or multiple devices,
if it is adapted accordingly)
ļµ 1 Emergency Power-off module (UE410-MU3T5 manufactured by Sick)
With adjustable delayed deactivation of the Compax3 enable input ENAin.
The time must be set so that all axes are at a standstill before the Compax3
controllers are deactivated.
ļµ The operating instructions of the UE410-MU3T5 safety switching device must be
observed.
ļµ 1 emergency power-off switch
ļµ Hazardous area accessible via a safety door with safety door switch S6.
ļµ 1 pushbutton per Compax3
ļµ For the Energize input on Compax3, a debouncing time > 3 ms must be
configured
ļµ 1 relay per Compax3
The relay must be dimensioned so that it has a lifetime of at least 20 years, taking
the cycle time into consideration. If this is not the case, the relays must be
exchanged for new relays after expiration of the lifetime.
