how do i change to stepper

[sdkpark]

i guess i am a bit confused of how these motors actually work. i'm sure i have stepper motors (MFA, UTM, MFN) by asking the xxQM? query, it replies 3. however, whenever i move the motor it goes by the resolution determined by xxFR, and xxSU, which in the manual clearly says encoder full step resolution.

how do i use the stepper motor to read/move the motor? i don't see any commands to set the stepper resolution and etc. any help is appreciated. thanks in advance!

Sam,

Are you trying to communicate with the motor in LabVIEW or some other system? Also, can you post the manual that you are referring to?

[sdkpark]

yes, i am trying to communicate with the motor using LabVIEW

here are the manuals

ESP300

If you don't mind, could you post your VI so we can see exactly what you're doing in LabVIEW?

i dont think the labview codes are relevant?

i'm just moving the motors by the AP (absolute position) commands. i believe using stepper or encoder is a setting in the motion controller, which i now think stepper is not an option for the ESP300...

can anyone confirm?

You can try through  LabVIEW or some other system? Consider to try munauylly, Thanks

Section 4.3 and 5.7 of the ESP300 User Manual discusses Stepper motors and how they are used in conjunction with the ESP300. So it is, in fact, an option for the ESP300.
