4.9.9 EMERGENCY STOP category 1; 230 V AC (option L59)
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 eight LEDs (-K120, -K121).

Setting
The time (0.5 to 30 s) set at the contactor safety combination (-K121) 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 -K121).
Diagnostics
Messages output during operation and in the event of faults (meaning of LEDs on -K120, -
K121) are described in the "Additional Operating Instructions" of the Operating Instructions.
