Optimization Of The Closed-Loop Control - Siemens Sinamics s120 Commissioning Manual

If p0306 is changed during quick commissioning (p0010 = 1), then the maximum current
p0640 is appropriately pre-assigned. This is not the case in the motor commissioning
(p0010 = 3)!
The motor data displayed in the STARTER commissioning tool is only valid for one motor
and is only internally interpolated up to N motors connected in parallel.

Optimization of the closed-loop control

When running through the drive configuration, in the step "Calculating the motor/controller
data", drive-specific controller parameters are calculated, see the "Screen form to calculate
motor/controller data (Page 245)" figure. However, to be able to use the optimal performance
of the machine, a subsequent optimization of the controller parameters is required. Higher
positioning/machining accuracy can be achieved and cycle times can be reduced by means
of optimized settings.
Controller optimization may only be performed by experienced specialists.
In the control, for optimizing the controller, there is the possibility of measuring frequency
responses or recording setpoint steps. Especially the frequency response measurement
allows machine-specific natural frequencies that restrict the bandwidth of the closed-loop
control to be taken into account.
You can ask your local Siemens office regarding optimization of the closed-loop control as a
service.
