I want to move my servo from S7-1200 via TIA portal but I have "7496 : EPOS enable not possible" error. Cause: It is not possible to enable the basic positioner because at least one signal is missing. Alarm value (r2124, interpret decimal): 1: EPOS enable missing (BI: p2656). 2: Position actual value, valid feedback signal missing (BI: p2658). See also: p2656 (EPOS enable basic positioner), p2658 (EPOS pos. actual value valid feedback signal) Remedy: Check the appropriate binector inputs and signals. p2656 = Drive_1 : r2526.3 CO/BO : LR status word : Cloaed-loop position control active (1 yes/ 0 no) p2658 = Drive_1 : r2526.0 CO/BO : LR status word : Position actual value valid (1 yes/ 0 no) This explanation is not clear for me. I think it is about P840 ON/OFF OFF1" = r2090.0 parameter on the attachment or maybe about actual position value. Whah should I do? Attachment EPOS.jpg (577 Downloads)
