Optimising the control mode

The "optimisation steps" given in the table below serve to further optimise the control
behaviour of the servo control and adjust it to the concrete application.
 Detailed information on the individual steps can be found in the following
subchapters.
Generally, the following optimisation steps are recommended:
Optimisation steps
1. Optimise current
• The current controller should always be optimised if a motor of a third-party manufacturer with
unknown motor data is used!
2. Optimise speed
• The setting of the speed controller must be adapted depending on the mechanical path.
3. Optimise response to setpoint changes and determine mass
• For an optimal reference behaviour, the total moment of inertia can be used to make a feedforward
control of the speed setpoint.
Special cases may require further optimisation steps:
Optimisation steps
1. Setting the current setpoint filter (band-stop
• In order to suppress or damp (mechanical) resonant frequencies, a current setpoint filter is integrated in
the speed control loop which is switched off in the default setting but can be parameterised accordingly,
if required.
Then readjust the speed controller:
2. Adapting the max. acceleration change (jerk
3. Optimising the behaviour in the field weakening

Tip!
In order to traverse a typical speed profile for optimisation of motor control, you
can also use the basic function
jog parameters if this basic function is supported by the selected technology
application.
