When online with FM 354, at start - up window , i just can read the actual value from my encoder but the setpoint and speed value is shown at zero value! I dont know why ! I followed all the preconditions in manual as following : +The FM 354 has been initialized. +The mode has been selected and acknowledged. +Drive Enable [AF] = 1 (control signal in user DB, DBX15.7) +Stop [STP] = 0 (control signal in user DB, DBX15.1) +Servo Enable (RF) = 1 (user DB, DBX34.0) +Speed levels have been transferred. then transfered value to SET_POS variable, DBD 322 ! So i am really worried,... Can you suggest any idea ? Thank you in advance :)

TrungPh Posts: 2 Rating: (0)	Hi apliedes, I tried DBD 156 but i think it is a parameter for Incr. mode, however it doesnt work anyway!!! I am now really confusing about setpoint value because i found very little infomation on setpoint value in manual tech. doc. so can anybody explain for me where and how i can parameterize the setpoint value in jogging mode or incr. mode , please ?! Urgent, I read the example for FM354 included in software package, but i couldnt find the setpoint value ,too!
