Local standardsand regulations should be always followed in the final design.Example 1: OPTBJ board without reset for Safe Torque Off (STO)The figure above shows a connection example of OPTBJ board for Safe Torque Off safety functionwithout reset. The switch S1 is connected with 4 wires to the OPTBJ board as shown above.When the switch S1 is activated (contacts open), the drive goes to STO state and motor (if running)will stop by coasting. If STO fault action is parameterized as "Alarm", the drive indicates: "30 Safetorque off". Regardless of the parameterization, activation of STO function causes a coasting stopfor motor.To allow the returning of the drive to ready state without a reset after S1 is deactivated (contactsclosed), STO Fault action must be parameterized as "Alarm". See application manual for related pa-rameters.To start the motor operation again, the following sequence is performed.• Release the switch S1 (contacts closed). The hardware is now enabled and the drive returns to readystate.• Giving a valid start command starts running the motor.NOTE! According to EN 60204-1 (Safety of machinery - Electrical equipment of machines), the re-setting of the emergency stop request (e.g. releasing of emergency stop button) must not restartthe drive.NOTE! The VACON® 100 default application software uses edge-sensitive start as a default startcommand. With the edge-sensitive start command, disactivating the STO does not cause immediatestart.F1123456L1 L2MAIN CIRCUITL3PEPEL1 L2 L3U V WPE27PEPEPEW1M1M3 ~U11V1 W12PER1SPEED REFERENCESCCWCWW12 1sh 1r 2sh 2p 2sBasic I/O1+10Vref12AI1+23AI13OPTBJSLOT E1STO1+2STO1S1 1112W10 1r 2r1b 2bS6START13144AI2+45AI25624Vout67GND73STO2+4STO22122S7STOP11128DI189DI2910DI31011CM1125RO1 C26RO1 NO28TI1+1224Vout1213GND1314DI41415DI515X23OFF29TI116DI61617CM1718AO1+1819AO/GND1930+24Vin20PESafe torque off+24V0VARS485BRS48521 22AO1RS485UUUON OFFIII AI2AI1Short circuit and earthfault protected supplyON OFF DGNDX10Installed3044B_UK.eps
