3. Encoder Settings:
If the ‘Control Strategy’ is set to ‘Vector Control’, and the ‘Control Type’ is set to ‘Encoder Feedback’
(Induction Motor only), the encoder mounted on the motor will also need to be set up.
If only one Encoder Feedback option card is fitted, the AC20 will automatically detect which slot the
Encoder Feedback card is fitted to.
If two Encoder Feedback option cards are fitted, the ‘Encoder Feedback’ parameter (0033) in the ‘Control
and Type’ menu needs to be set to indicate which slot is to be used for the speed feedback.
Note: See Section 6.3.3 for wiring example.
