Is droop oscillation
0.045°p-p or less?
Note that the maximum setting value is as follows:
SP005(max) ≤ 150 × inertia ratio
(Inertia ratio total inertia/motor inertia
(Example)
When inertia rate is double and the determined gain is
350, the setting value for SP005 is 315, which is 90%
of the determined gain, however,the setting value for
SP005 should be 300, because the maximum setting
value is 150×2(inertia rate)=300.
Executes acceleration/deceleration operation in phase
up to maximum rotation speed from 0.
(Note)
When the maximum speed is 10000r/min, executes in
approx. 1000r/min increments, divided by 10.
(Note)
NC analyzer cannot create a program when acquiring a
spindle waveform. The program is created on the NC
side.
< NC Analyzer setting (Time-series data measurement) >
Set the "Time-series data
measurement" with NC Analyzer
as shown on the right.
