P20 Group--Encoders - INVT Goodrive3000 Series Operation Manual

Goodrive3000 series medium voltage VFD
P20 group––Encoders
Function
code
P20.00
The function code is used to select an encoder type.
Note: An expansion card is required.
Function
code
P20.01 Encoder pulse count 0–60000
The function code is used to set the encoder pulse number per rotation.
Function
code
P20.02
Note: Please set the encoder pulse number correctly under the closed 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).
Function
code
P20.03
encoder offline fault
P20.04
encoder reversal fault
P20.05
encoder detection
P20.03 defines encoder offline detection time. When the offline time exceeds the set time, the VFD will alarm encoder
offline fault (ENCIO).
P20.04 defines encoder reverse detection time. When the reverse detection time exceeds the set time, the VFD 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.
Function
code
Speed ratio between
P20.06
motor and encoder
The function code is used to set the speed ratio between motor and encoder. Set the value according to the actual
conditions.
