If the backlash compensation setting is different for each axis in an interpolation
operation, during the period that interpolation is being executed for both axes
simultaneously, the axes will wait for the compensation to be completed and
then accelerate.

9-9-1 Outline
In order to prevent damage to external devices due to unexpected positioning
operation when there is a malfunction, in addition to the CW and CCW limit input
signals, the PCU also has a function that monitors the position at a software
level. This function is called the “software limit” function. The range in which the
software limit function monitors the position is determined by the values of two
settings: the CW software limit and the CCW software limit. Normally, position-
ing is only possible within the range determined by these settings.
