Hello 

İ have g130 and cu320-2 . i  used analog input for main setpoint via tb30 optional module.

if analog input gives negative voltage motor run backward . it should run forward all time. how can i

inhibit negative direction.

also i have 2 jog speed via  using jog bits 1 is 300 rpm 2. is -300 rpm .

hello

if i activate 1110 inhibit negative direction how can i run jog speed negative(-300).

By setting P1110 = 1 inhabit negative direction & activate P1055 & P1056 JOG can be activated. 

hello

if i activate 1110 inhibit negative direction how can i run jog speed negative(-300).

Please refer the attached FD. JOG set point is fed after  main set point processing.

 hello

parameter 1110 inhibit negative direction is after jog and main setpoint.

please  look at attachment

any other answer?

Have you checked p1086?

If necessary you can work with datasets.

Or you work with a offset at the analogue input and / or with the absolute value generation (on TB30: p4066)

 no p1086 and offset are not  a solution for my problem. what p4066  is doing?

... it keep the value always positive - so -1V would be +1V

But you can use a offset too - it´s a question of normalization.

 hello,

After p4066=1 ;

analog signal -5v ---> 5v 

analog signal  5v---->5v  

right?
