Motor Module: Known problems with Release 6-8
Although there are a number of improvements with R6-8's support of soft-travel
limits (LVIO), there are also two problems that will remain "Known Problems"
until at least the next bug-fix release. These limitation are as follows:
Tweaking (TWF/TWR) very small increments with UEIP = Yes while in the invalid
range of the soft-travel limits may put the motor record in a state where the
user cannot tweak in either direction. The solution is to either jog the motor
towards the valid range or increase the tweak increment value (TWV field).
Tapping the Jog button can cause the motor to move past the soft-travel limit
when backlash is nonzero.
