EMERGENCY STOP category 1; 24 V DC (option L60)
Description
EMERGENCY STOP category 1 for controlled stop according to EN 60204-1. The function
includes rapid shutdown of the drive via fast stop at a ramp-down ramp to be parameterized.
Then the cabinet unit is disconnected from the power supply via the line contactor, while
bypassing the electronics by means of a safety combination according to EN 60204-1.
The operational status and function are indicated by five LEDs (-K120).

Setting
The time (0.5 to 30 s) set for the contactor safety combination (-K120) should be longer 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), as the converter is disconnected from the power supply
when the time expires (at -K120).
Diagnostics
Messages output during operation and in the event of faults (meaning of LEDs on -K120) are
described in the "Additional Operating Instructions" of the Operating Instructions.
