EMERGENCY STOP category 1; 230 V AC (option L59)

Description
EMERGENCY STOP category 1 for controlled stop to EN 60 204. 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 60 204-1).
The operating status is indicated by means of eight LEDs (-A120, -A121).

Setting
When the quick stop function (OFF3 ramp-down time, p1135) is used to shut down the drive,
the ramp-down time should be less than (or at the most equal to) the time set on the
contactor safety combination, after which the converter is de-energized.
Diagnosis
Messages output during operation and in the event of faults (meaning of LEDs on -A120, -
A121) are described in "Additional Operating Instructions" in the operating manual.
