Function
The secondary part conducts linear movements across the indicated stroke length.
The motor of the machine is controlled via servo amplifier. A high level of positional accu-
racy and repeat accuracy are achieved through the integrated measuring system.
The positional accuracy describes the acceptable tolerance of the linear unit for an ope-
rating command involving movement to a specified position. It is determined by mechani-
cal tolerances and the accuracy of the measurement system. Furthermore, the positional
accuracy is influenced by external and internal temperature changes. The specified posi-
tional accuracy is attained for temperatures within a range of +/-15°C.
The repeat accuracy describes the deviation of the linear unit, which is permissible for
the repeated movement to the same position - even after repeated switch on and off. It is
influenced by external and internal temperature changes as well as the condition of the
mechanical stops for the referencing. The specified repeat accuracy only applies at a
constant temperature of +20°C and without any external strain.
