Lock speed I Not active (H) I component of the speed regulator is enabled
Active (L) I component of the speed regulator is disabled
Aux spd fun sel Selection of the Speed up or Inertia/loss cp (see chapter 6.7.3. Speed up function and
chapter 6.7.5. Inertia/loss cp for more details).
Prop filter Time constant of the filter belonging to the circuit of the speed feedback. Filtering of
the high frequency components of speed feedback signal is useful in case of elastic
coupling between motor and load (joint or belts).
The speed regulator must be enabled with the Enable spd reg parameter in order for it to be used.
The reference value for the speed regulator consists of the signed addition of Speed ref 1 and Speed ref 2.
The speed feedback is supplied by an encoder or a tachometer that are mounted to the motor shaft. The higher
the resolution of the encoder, the better the control accuracy of the regulator.
The regulator parameters can be set separately.
For the speed PI regulator diagram block, please refer to diagram on chapter 9.
