4.9.10 EMERGENCY STOP category 1; 24 V DC (option L60)
Description
EMERGENCY STOP category 1 for controlled stop to EN 60204-1. This function stops the
drive by means of a quick stop along a deceleration ramp that must be parameterized. The
cabinet unit is then disconnected from the power supply via the line contactor, which
bypasses the electronics by means of a safety combination to EN 60204-1.
The operating status and the function are indicated by means of five LEDs (-K120).

Setting
The time (0.5 to 30 s) set at the contactor safety combination (-K120) should be greater (or
at least identical to) the time that the drive requires to reach standstill via quick stop (OFF3
ramp-down time, p1135), since the converter is disconnected from the power supply after
expiry of the time (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.
