Motor control (MCTRL)
Sensorless control for synchronous motors (SLPSM)
Using the ramp response for setting the speed controller
If the mechanical components cannot be operated at the stability limit, the ramp response
can also be used for setting the speed controller.
Stop!
If the controller parameters are preset unfavourably, the control can tend to
heavy overshoots up to instability!
• Following and speed errors can adopt very high values.
• If the mechanics are sensitive, the corresponding monitoring functions are to
be activated.
Note!
For an optimal setting, we recommend to determine the mass inertia (optimal
response to setpoint changes) first.
