(22…12 AWG)Safe torque off connection (XSTO)
Maximum tightening torque 0.45 N·m (4 lbf·in[BCU])
Input voltage range: -3…30 V DC
Logic levels: "0" < 5 V, "1" > 17 V.
Note: For the unit to start, both connections must be “1”. This
applies to all control units (including drive, inverter, supply, brake,
DC/DC converter etc. control units), but SIL/PL classified Safe
torque off functionality is only achieved through the XSTO con-
nector of the drive/inverter control unit.
Current consumption (continuous) per STO channel:
• Frames R1i…R4i: 56 mA
• Frame R5i: 21 mA
• Frames R6i…R7i: 41.5 mA
• Frames R6i…R7i with option +V992: 25 mA
• Frame R8i with BCU control unit: 66 mA per parallel inverter
