Note, TRAServer consists of 6 daisy chained SMC100 controllers.
After some troubleshooting, it was found that setting the backlash variable using the standard command set via the labview driver does not actually set the backlash on the hardware. It also does not provide any error.
The backlash can be set directly through the SMC100 configuration software (provided by newport). The settings are saved and can even be read by labview.
