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

Description
EMERGENCY STOP category 1 for controlled stopping according 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, while bypassing the electronics by means of a safety combination (according to
EN 60204-1).
The operating state and the function are indicated by eight LEDs (-K120, -K121).
Connecting
Table 4- 47

Max. connectable cross-section: 4 mm²
Setting
The time (0.5 to 30 s) set for the contactor safety combination (-K121) should be longer than
(or at least equal to) the time that the drive requires to reach a standstill via the quick stop
(OFF3 ramp-down time, p1135), as the converter is disconnected from the power supply
when the time expires (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.
