16.3.8 Optimizing the integral factor
MP7290: "0" (display step = 1 µm)
Machine stands in position, under servo control.
↓
MP1080 integral factor (for X axis):
raise entry value 1) , until the
Servo positioning becomes noticeably unstable
(observe the actual value display).
↓
MP1080: reduce the entry value in small steps
until the servo positioning is steady again 2).
↓
Repeat adjustment for Y axis, Z, and IV.
Whether or not an integral factor is possible in connection with the automatic offset adjustment with
MP 1220 can only be judged when observing the complete machine.
The optimum solution must be found during the commissioning procedure.
1) First entry value 100, raise subsequent values in steps of 100.
2) For drives which are not quite free of backlash the entry value should be "0".
