6 Spindle Adjustment
Execute cycle operation with the
acceleration/deceleration up to the
maximum speed in constant output
Stop the spindle (servo OFF)
[Temperature] on the spindle
monitor is ≦ 80?
Execute cycle operation with the
acceleration/deceleration up to the
maximum speed in constant output
[AFLT gain(dB)] on the
spindle monitor is ≦ 110?
Change SP226(SFNC6) from 0100
to 0000 (display the temperature
compensation adjustment indicator)
Change the current limit
(acceleration) back
CAUTION
1. Carry out the adjustment within the motor's specified ambient temperature range (0 to +40°C).
2. This function is unavailable if the time taken to accelerate to the maximum speed in constant output is shorter than 0.1[s].
Make sure to perform such acceleration/deceleration that reaches the maximum rotation speed in constant output.
3. If you program a command for accelerating up to the maximum speed in constant output, insert a dwell time so that the
spindle motor can reach the maximum speed.
4. Do not use this function for a spindle motor if it has a direct cooling system on the secondary side (rotor).
5. Before starting the adjustment, make sure that [Temperature (°C)] on the spindle monitor is close to the room
temperature.
If [Temperature (°C)] is unchanged or any error is found during the adjustment, do not use this function.
6. Do not change the spindle motor cooling condition after the parameter adjustment for this function is complete.
Also make sure to change SP226(SFNC6)/bit8 back to 0.
IB-1501229-F
Set SP236(WIH)=10
NO
* If it is difficult to increase the actual temperature up to
100°C, check the temperature until it reaches [Upper
YES
limit of temperature in practical use - 20°C].
NO
YES
NO
[AFLT gain(dB)] on the
spindle monitor is ≧ 90?
YES
Finish
Continue until [Temperature (°C)] on the
spindle monitor becomes ≧100.
* 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.
Decrement SP236(WIH) by 2
*The lower limit of setting is 1.
Increment SP236(R2H) by 2
(Note) Turn OFF/ON the NC power after this change.
