Title: Variable velocity jogging with AXJOG?
Post by: JasonO on June 11, 2026, 12:45:35 PM

I'm retrofitting a control that includes 2 servo axes, which I will control with step and direction outputs from a BRX. I need to be able to move the axes to preset positions, which is easy enough. I also need to be able to jog them manually with analog joystick, with the target velocity scaled from the analog input. In other words, the axis velocity needs to be dynamically updated based on the analog input signal, while the jog is in process. I don't think I've ever done this particular sort of thing before, so I wanted to see if someone can verify that this can work, and how.

Thanks!

Looks like maybe I need to use AXVEL to achieve this, with the .TargetVelocity dynamically update from the scaled analog value, as log as the instruction is active?
