EMERGENCY OFF Category 1; 230 V AC (Option L59)
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 a total of eight LEDs.

the time set on the contactor combination, after which the converter is de-
energized.
