Setting Axis Units

Figure 4-14: Setting Axis Units

Some guidelines for suitable settings advises for a good choice is given below:

The unit is adapted for the machine
The unit must be meaningful for the user
The same unit must be used for all related axes, for reasons of simplicity
The unit must be set as soon as possible and must not be changed during the program lifetime, for reasons of consistency
Speed is defined in User Units for position / second
Acceleration in User Units for position / second²
The unit must be related to the final moving object, instead of any intermediate part (e.g. the driven belt rather than the motor or axis shaft, which are intermediate parts)
