Circuit diagram
This diagram is an example circuit diagram without the safety encoder interface. For more
information, see the circuit diagrams of the delivery.
Initial status: The drive is in operation and the motor is running.
Step Operation
1. The user activates the emergency stop function by pushing the emergency stop button [S61]. This
activates the safety function in the FSO module.
2. The drive decelerates/coasts the motor to zero speed using the user-defined stop category (0 or 1).
The STO circuit in the drive/inverter unit is opened.
3. The emergency stop indication lamp [P62] illuminates as described in section Operation principle
on page 18 .
4. Normal operation resumes after the user:
• releases the emergency stop button [S61] to normal (up) position
• resets emergency stop circuit by pushing the emergency stop reset button [S62]
• switches the external start signal of drive off and on (only in external control mode)
• resets the drive if a fault is generated (see FSO parameter
FSOGEN.61 STO indication ext
request on page 37 and drive parameter 31.22 STO indication run/stop on page 44 ).
