Kollmorgen AKD-P00607-NBEC-0000 400/480VAC 4.40KVA Servo Drive.

Safe Torque Off (STO)

Anadditional digital input (STO) releases the poweroutput stageof thedriveas longas a24V signal is appliedto

this input. If the STO input goes open-circuit, then powerwill nolongerbesuppliedtothemotor, andthedrivewill

lose all torque and coast toastop.

Input STO (X1/3)

—Floating, reference groundis GND

—24V±10%,20mA

ThisinputisnotcompatiblewithIEC61131-2.

Youcanthus achievearestart lock-out forpersonnel safety by usingtheSTOinput inconjunctionwithanexter

nal safety circuit.

Advantages of theSTOfunction:

l TheDCbuslink remains charged, sincethemains supply lineremains active.

l Onlylow voltages areswitched, sothereis nocontact wear.

l Verylittle wiring is required.

TheSTOsafety concept is certified. Thesafety circuit concept usedforthesafety function”SafeTorqueOff” in

the drive is suited for SIL 2accordingtoEN 61800-5-2andPLd/ CAT3accordingtoISO13849-1.

TheSTOfunctionis exclusively intendedtoprovidesafety forpersonnel by preventingtherestart of asystem.

Toachievethis personnel safety, thewiringof thesafety circuits must meet thesafety requirements of IEC

60204. ISO12100andISO13849.
