MC4N-ECAT and sanyo denki following error

Good day,
i have used MC4N-ECAT to control sanyo denki servo thru ethercat. i facing a problem on the actual postion feedback issue. My sanyo denki servo motor is an absolute encoder. I facing the feedback following error. the due to the servo motor is absolute encoder, when the motor turn 1 round the encoder will reset to 0. when the encoder reset to 0 the target position and the actual encoder feedback will become not same then following error alarm will come out. what can i do to resolve this problem?
