Operating Manual
4.9.9 EMERGENCY OFF Category 1; 24 V DC (Option L60)
Description
EMERGENCY OFF category 1 for controlled stop to EN 60 204. This function
involves stopping the drive by means of a rapid stop using a deceleration ramp that
can be parameterized by the user. The cabinet unit is then disconnected from the
supply via the line contactor bypassing the electronics by means of a safety
combination to EN 60 204-1. A braking unit may be necessary to achieve the
required shutdown times.
The operational status is indicated by means of five LEDs.

Setting
When the emergency 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 combination, after which the converter is de-
energized.
Diagnostics
Messages output during operation and in the event of faults (meaning of LEDs) are
described in “Additional Operating Instructions” in the operating manual.
