Example 2: OPTBJ board with reset for Safe Torque Off or EN 60204-1 stop category 0.
The figure above presents a connection example of OPTBJ board for STO safety function with reset.
The switch S1 is connected with 4 wires to the OPTBJ board as shown above. The digital input 3
(DIN3), for example, is wired for the fault reset function. The reset function (not part of any safety
function) can be programmed to any of the available digital inputs.
The power supply to S1 may come from control board (connector pins 6 & 7 in Figure above) or it
may also be external, if earth fault and short circuit protected.
When the switch S1 is activated (contacts open), the drive will go to STO state and motor (if running)
will stop by coasting. The drive will indicate: "30 SafeTorqueOff".
To start the motor operation again, the following sequence is performed.
• Release the switch S1 (contacts closed). The hardware is now enabled but the drive continues to dis-
play the fault "30 SafeTorqueOff".
• Acknowledge the releasing of switch by edge sensitive reset function. The drive returns to the ready
state.
• Giving a valid start command will start running the motor.
NOTE! The Vacon 100 default application software uses edge-sensitive start as default start com-
mand, for preventing unexpected startup from STO state.
NOTE! For EN 60204-1 emergency stop according to stop category 0, use the emergency stop but-
ton.
