why the incermental encoder give speed feed back but not give the direction feed back when connected to DCS800
I am tried to commission a DCS800 DC Drive.
The motor feedback is taken from incremental encoder 1024 ppr, 9-30 VDC.
After the tuning the Encoder gives good speed feedback, but not direction feedback.
I try every connection configuration; direction feedback is not measured by the drive.

I do find the answer to my question !!
it is the Jumpers settings (S4)
using jumpers conifuration to select the power to be applied to the Enconder , and the type of encoder .
for the detailed information kindly see Page 58 in ABB document (3ADW000194R0601 DCS800 Hardware Manual f e)
