Standard optimization parameters
The above figure shows the parameters for the standard group. With the aid of
these parameters, you can optimize the standard cascade structure.
Control signal limitations
In this chapter you can read about:
Limitation of hte setpoint velocity.....................................................................................................153
Limitation of the setpoint current......................................................................................................153
Limitation of the control voltage .......................................................................................................153
The cascade structure shows that a limitation block is available in the control signal
sector of each controller. The limitations of the position and velocity loops are
calculated from the set limitations in the configuration and the motor parameters of
the selected motor.
