11.3 Quick stop

In contrast to Stop, the purpose of quick stop (QSP) is a stop in case of error. If quick stop is activated,

the drive is brought to standstill within the deceleration time set irrespective of the setpoint that is

preselected.

 Tip!

Quick stop can also be set as error response for many monitoring functions ("quick stop by

trouble"). Detailed information can be found in the chapter "Diagnostics & fault analysis

".

The source from which the quick stop was activated is shown in a bit coded manner in

11.3.1 Internal interfaces | "LS_Quickstop" system block"

The LS_Quickstop system block provides the internal interfaces for the basic function "Stop" in the

function block editor.

 Note!

Through this, superimposed controls (e.g. synchronous or position control) may produce

following errors. If several drives execute a coordinated motion, the quick stop function

should only be used for the motion master (master drive) in order to maintain the

coordination.

When the basic function is activated, a start acceleration is considered. Start

acceleration/acceleration reduction when the basic function changes ( 380)

 Note!

Ensure that the system block is called in a cyclic application task.

Basically, projects which only contain an unsolicited task and no cyclic task are not

permissible!
