6 Spindle Adjustment
< How to adjust the spindle motor temperature compensation function >
Start the adjustment
Set the temperature compensation
parameters to the initial settings:
SP235(R2H)=150, SP236(WIH)=0
Change the current limit (acceleration)
[Cycle counter] on the
spindle monitor is ≠0?
Stop the spindle (servo OFF)
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
[AFLT gain(dB)] on the
spindle monitor is ≦ 110?
[AFLT gain(dB)] on the
spindle monitor is ≧ 90?
[Temperature] on the spindle
monitor is ≧ 100?
Stop the spindle (servo OFF)
Change SP153 and SP185 to [original setting x 0.8]
respectively.
(Note) Turn OFF/ON the NC power after this change.
Forward-run the spindle
(command speed at approx. 60r/min)
NO
YES
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.
Decrement SP235(R2H) by 5
* The lower limit of setting is 100.
NO
* If you reduce SP235(R2H) too much, excessive
compensation will result and [AFLT gain (dB)] will be too
YES high. In this case increment the setting by 5.
Increment SP235(R2H) by 5
NO
YES
NO
* If it is difficult to increase the actual temperature up to
100°C, check the temperature until it reaches the upper
YES
limit of temperature in practical use.
Adjusting SP235(R2H) is complete.
