Precise stopping with Quick Stop – even at a high speed

Quick and reproducible response to process states, saving of distributed I/O

The motor and thus the conveyed material can be stopped via the integrated Quick Stop functionality irrespective of the PLC cycle time and reproducibly.

For this purpose, the sensor is wired directly to the motor starter / inverter.

The Quick Stop function is activated or deactivated, when conveying is to be continued, non-time-critically by the PLC. The sensor status is transmitted to the PLC.

Application example:

Stop light barrier of a conveyor element


 

This is an integrated function of the following motor starters / frequency inverters:

A quick stop functionality can be implemented in the converter via the basic PLC functionalities (free function blocks) of the following devices (s. example):
