Start the adjustment
Change SP153(TMLD*) and SP185(TMLDL*) to
[original setting x 0.8] respectively.
(Note) Turn OFF/ON the NC power after this change.
[Cycle counter] on the
spindle monitor is ≠0?
Stop the spindle (servo OFF)
Set the temperature compensation
parameters to the initial settings:
SP235(R2H)=150, SP236(WIH)=0
Change the current limit (acceleration)
Forward-run the spindle
(command speed at approx. 60r/min)
For the initial operation after setting SP226/bit8 = 1,
make sure to perform acceleration/deceleration that
reaches the maximum rotation speed in constant output.
If the acceleration/deceleration has not reached
the maximum speed, set SP226/bit8=0 once,
and then SP226/bit8=1. This resets the display.
[AFLT gain(dB)] on the
spindle monitor is
110?
Decrement SP235(R2H) by 5
* The lower limit of setting is 100.
[AFLT gain(dB)] on the
spindle monitor is
90?
[Temperature] on the spindle
monitor is
100?
* If you reduce SP235(R2H) too much, excessive
compensation will result and [AFLT gain (dB)] will be too
high. In this case increment the setting by 5.
Increment SP235(R2H) by 5
Stop the spindle (servo OFF)
* If it is difficult to increase the actual temperature up to
100
°C
, check the temperature until it reaches the upper
limit of temperature in practical use.
Adjusting SP235(R2H) is complete.
Change SP226(SFNC6) from 0000 to
0100 (display the temperature
compensation adjustment indicator)
Execute cycle operation with the
acceleration/deceleration up to the
maximum speed in constant output
