5.5.3 Optimising the control mode

A manual optimisation of the controller settings may be required for very dynamic applications and

in the field weakening range.

Based on the typical controller settings which are listed in the chapter "Parameterising speed and

torque controller" in table [5-8], first the field feedforward control and the speed controller are

optimised in the base speed range. Afterwards, the torque controller is optimised in the field

weakening range.

For optimisation, a suitable speed ramp must be selected for the drive and the acceleration must be

recorded, e.g. using the Oscilloscope

function in »Engineer«. ( 579)

Short overview: Parameters for controller settings

 Note!

The processes for optimising the controller settings described in the following

subchapters can only be executed while the drive is rotating and never when being at

standstill!

For all optimisation processes the magnetisation phase has to be completed!
