4. PARAMETERS FOR POSITIONING CONTROL
4 − 2
4.2 Fixed Parameters
(1) The fixed parameters are set for each axis and their data is fixed in accordance
with the mechanical system or other factors.
(2) The fixed parameters are set with a peripheral device.
(3) The fixed parameters to be set are shown in Table 4.1.
