L_MC1P: QSP application: When activated during standstill, no compensation of the contouring error takes place, contouring error monitoring responds if necessary.

Corrected from:

Library: L_MC1P_MotionControlBasic (FAST Motion) from V03.29.xx (in planning)

(Update via Package Manager)

Response of the new version:

What happens?

A compensation movement to the last target position takes place because the currently pending tracking error is incorrectly not reset when the QSP application is activated.

The distance corresponds to the contouring error present at activation.

If tracking error monitoring is activated (recommended), it responds when the set tolerance (Sub :056) is exceeded.

When does the behaviour occur?

Execution of a quick stop (QSP application) if the standstill has already been reached and
there is still a drag error at the time.

Which products are affected?

Library: L_MC1P_MotionControlBasic (FAST Motion)

Short-term measures / evaluation / recommendations:

In most applications, the tracking error that occurs during movement will already be largely compensated for when standstill is reached.

The effects of the behaviour described will be correspondingly less serious if the tracking error is only small.

At higher values, the tracking error monitoring should respond in order to prevent unwanted movements.

--> The error reaction of the tracking error monitoring must therefore remain set to "Fault QSP".

The QSP function of the inverter intervenes in case of error reaction 'Fault QSP'.
