Step Operation
Initial status: The drive is in operation and the motor is running.
1 The user pushes the emergency stop button [S61]. This activates the emergency stop function.
2 The emergency stop safety relay [A640] de-energizes XSTO inputs IN1 and IN2 of the inverter
control unit [A41]. This activates the inverter unit Safe torque off function.
The emergency stop safety relay [A640] de-energizes the DIIL input on the supply control unit [A51].
This gives the emergency stop command to the supply unit.
The emergency stop safety relay [A640] de-energizes the safety relay [K640].
The safety relay [K640] opens the main contactor/breaker [Qx], which disconnects the input power
from the supply unit [T01].
The charging contactor [Q4] is opened, if the emergency stop is activated during charging.
