EMERGENCY STOP category 1; 115 V AC (option N59)
Description
EMERGENCY OFF category 1 for controlled stop according to IEC 60204-1. The function
includes the stopping of the drive via an emergency stop according to an assigned ramp-
down. This is followed by 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 operational status and function are indicated by a total of eight LEDs (-K120, -K121).

Setting
The time (0.5 to 30 s) set for the contactor safety combination (-K121) should be greater
than (or at least equal to) the time that the drive requires to reach a standstill via the quick
stop (OFF3 ramp-down time, p1135), because the converter is disconnected from the energy
supply when the time runs out (at -K121).
Diagnostics
Messages output during operation and in the event of faults (meaning of LEDs on -K120,
-K121) are described in the operating instructions included on the customer DVD supplied
with the device.
