EMERGENCY STOP category 1; 24 V DC (option L60)

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, bypassing the
electronics by means of a safety combination (to EN 60 204-1).
The operating status is indicated by means of five LEDs (-A120).

contactor safety combination, after which the converter is de-energized.
