If the connected Model 430 has a ramp rate timebase of minutes selected, the commanded ramp rates from the Multi-Axis Operation application are a factor of 60x too low as the value sent is assumed to be in units of A/s.
The present workaround is to set the ramp rate timebase to seconds in all connected Model 430 units.
This issue was addressed in version 0.93 by forcing all Model 430 devices to use ramp units of A/s when connected. Working with the Multi-Axis Operation app in ramping units of minutes is not currently supported.
