L_CT1P: Autotuning function: Exception occurring when parameterising the gain Vp=0 (corrected from V03.24.00)

Corrected from:

Library: L_CT1P_ControlToolbox (FAST Motion) from V03.24.00.40

(Update via Package Manager)

Response of the new version:

The case of gains parameterised to zero is now intercepted by the software, so that the exception described no longer occurs.

What happens?

AutoTuning: At the end of the AutoTuning process, an exception occurs with certain parameterisation.

When does the behaviour occur?

AutoTuning function AND
At the beginning, the gain of the position controller and/or the speed controller is parameterised as zero:
Position controller gain Vpp = 0
Speed controller gain Vpn = 0

Which products are affected?

Library: L_MC1P_MotionControlBasic (FAST Motion)

L_CT1P_ControlToolbox (FAST Motion)

Short-term measures / Evaluation / recommendations:

Before starting the AutoTuning function, do not parameterise the controller settings to zero.

It is recommended to start AutoTuning with the default values of the engine used. The default values are rather soft, so that they are sufficient as initial values. As a result of the optimisation, higher amplification values are usually determined.
