Wiring examples
The examples in this chapter show the basic principles for wiring OPTBJ board. Local standards
and 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 function
without reset. The switch S1 is connected with 4 wires to the OPTBJ board as shown above.
The power supply to S1 may come from control board (connector pins 6 & 7 in the above Figure) or
it may also be external.
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.
