ALL STOP, coast to stop (option N55)
Description
The mushroom pushbutton with protective collar and interlock is mounted in the door of the
enclosed drive and its contacts are wired to the OFF2 terminal of the Control Unit. After the
pushbutton is actuated, the motor coasts to a stop.
4.9.8
EMERGENCY OFF category 0; 115 V AC or 24 V DC (option N57)
Description
EMERGENCY OFF category 0 for uncontrolled stop according to IEC 60204-1. This function
includes the interruption of the energy supply of the enclosed drive via the line contactor by
bypassing the electronics by means of a safety relay according to IEC 60204-1. The motor
coasts down. To prevent the input contactor from switching under load, an OFF2 is triggered
simultaneously.
No additional wiring is needed when using the EMERGENCY OFF pushbutton.
The operational status and the function are indicated by three LEDs (-K120).
In the factory state, the type with 115 V AC button circuit is set.
Note
Pressing the EMERGENCY OFF button
When the EMERGENCY OFF pushbutton is pressed, an uncontrolled stop of the motor
takes place and the main motor voltage is disconnected in accordance with IEC 60204-1.
Auxiliary voltages (e.g., for separately-driven fans or anti-condensation heating) may still be
present. Certain sections of the converter (e.g., the closed-loop controller or any auxiliary
equipment) also remain live. If all the voltages have to be completely disconnected, the
EMERGENCY OFF pushbutton must be integrated in a protection concept, which must be
implemented on the line side. A normally closed contact is available at terminal -X120 for this
purpose.
