PowerFlex 700s for the Feedback speed of motor

[nguyenmauhien08118]

Hi everyone
I need connect encoder with PowerFlex 700S for the feedback speed of motor.
Power supply of encoder is 5 V, so i used internal power of PowerFlex 700S by turning on and of switch in jump 5.
When i change mode from sensorless into encoder 0 or encoder 1 in parameter 222, it warm that not encoder is connected although i checked A channel of encoder by opsolocope and it is OK.
Plesase help me how configure parameters and hadwares to receive the feedback pulse?

What type of encoder are you using and how have you wired it ?
How have you configured P230(for encoder 0) P243(for encoder 1)
