Hi, Help me! I have applied to operate using analog drive FX3U-4DA, but I do not know how to use positioning. Could you please tell me, indicating that the instruction command has Positioning with analog output? Have any examples? I never did with analog application. Thanks Edited by mr.Nilson-Brasil

What programming software do you use? GX Developer? GX IEC Developer? GX Works 2?

I do not know what you mean, a command to do positioning via analog. Analog is simply storing a number to a register, it has nothing to do with positioning. And if you are using an analog output to run a servo or VFD in analog mode, there is no dedicated commands in the PLC for this.

You can only use this for speed or torque control but not for actual positioning. You would need a F3U-20SSC-H special function module for using a servo in position control. But if you only want to have speed control and not position control than you can by analog output.
