P20.00 Encoder type
Select the encoder type.
Note: It is necessary to select the optional card.

P20.02 Encoder direction
Note: Please set the encoder pulse number correctly under the close loop vector control mode
(P20.01); otherwise, the motor will not run properly. If it still cannot run properly after parameter
setting of the encoder, change the encoder direction (P20.02).

filter times
P20.03 defines encoder offline detection time. When the offline time exceeds the set time, the inverter
will alarm encoder offline fault (ENCIO). P20.04 defines encoder reverse detection time. When the
reverse detection time exceeds the set time, the inverter will alarm encoder reverse fault (ENCID).
Note: Adjusting above parameters will influence the flexibility of encoder fault protection and
sometimes abnormal actions may occur, so adjust carefully.
