OperationStep
Initial status: The drive is in operation and the motor is running.
The user activates emergency stop with the emergency stop button [S61]. This activates the safety
function in the FSO module.
1
Emergency stop, stop category 0: The FSO module [A68] activates the drive STO function and opens
the main contactor/breaker [Qx]. If the emergency stop is activated during charging, the charging
contactor [Q4] is also opened. The motor coasts to a stop.
2
Emergency stop, stop category 1: The drive decelerates the motor to zero speed. The FSO module
[A68] then activates the drive STO function and opens the main contactor/breaker [Qx]. If the emer-
gency stop is activated during charging, the charging contactor [Q4] is also opened.
The emergency stop reset button indicator light [S62] comes on.3
The DIIL input of the supply control [A51] is de-energized. This gives the emergency stop command
to the supply unit.
4
Normal operation resumes after the user:
5
• releases the emergency stop button [S61] to normal (up) position
• pushes the emergency stop reset button [S62], which resets the emergency stop circuit and closes
the main contactor/breaker [Qx]
• switches the external start signal of the drive off and on (only in external control mode)
•
resets the drive/inverter unit if a fault was generated (see FSO parameter FSOGEN.61 STO indic-
ation ext request, and drive parameter 31.22 STO indication run/stop).
