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.
To prevent starting the motor without reset, STO fault action has to be parameterized as "Fault".
See application manual for related parameters.
When the switch S1 is activated (contacts open), the drive goes to STO state and motor (if running)
stops by coasting. The drive indicates: "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 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 restart
the drive.
NOTE! The VACON
®
100 default application software uses edge-sensitive start as a default start
command. With the edge-sensitive start command, disactivating the STO does not cause immediate
start.
NOTE! For EN 60204-1 emergency stop according to stop category 0, use the emergency stop but-
ton.
