2.SPECIFICATIONS FANUC AC SPINDLE MOTOR αiL SERIES B-65272EN/04
- 212 -
Cautions and limitations
(*1) The power wire switching method is Y-Y switching. Refer to
FANUC SERVO AMPLIFIER αi series DESCRIPTIONS (B-
65282EN) for explanations about output switching control.
(*2) The rated output is guaranteed at the rated voltage.
(Amplifier input: 200 to 230VAC)
If the input voltage fluctuates, it is possible that the rated output
cannot be obtained even when such fluctuations are within the
allowable fluctuation range.
(*3) The cycle time is 10 minutes, S3 60%: ON 6 minutes, OFF 4
minutes, S3 40%: ON 4 minutes, OFF 6 minutes, S3 25%: ON
2.5 minutes, OFF 7.5 minutes
(*4) The rated current is the maximum current for each rated output.
(*5) IC code conforms to IEC 34-6. Apply cooling conditions
stipulated elsewhere.
(*6) IM code conforms to IEC 34-7.
(*7) This is not a guaranteed value but a guideline for the maximum
motor output at a rated supply voltage.
(*8) Type conforms to IEC 34-11.
(*9) When assembling a motor with the machine, align the motor
shaft with the spindle so that the vibration acceleration of the
motor does not exceed 0.5 G (at maximum speed).
(Before shipping machines, check that the vibration acceleration
is 0.5 G or less for all motors.)
(*10)Select a coupling that does not apply a thrust load onto the
motor shaft for a cause such as coolant pressure when the
temperature rises.
Note that in the direction in which the motor shaft is pushed
toward the inside of the motor, the allowable load is 0 kgf.
(If a gear coupling or Oldham coupling is used, the motor shaft
can be left pushed into the inside of the motor when the motor
shaft is inserted into the spindle. So, measure the distance
between the mounting face for a rotation joint support housing
and the flinger rear end face before and after insertion, and check
that the two measured values are identical.
For details, see Section 9.4 "COUPLING SELECTION" in Part
IV.)
(*11)These values are to be used only as guidance for selecting a
power supply module and are not guaranteed.
(*12)The protection grade (IEC34-5) is IP40. However, the grade is
IP54 when the labyrinth seal on the front side of the output axis
and the flinger seal on the rear side are excluded.
Ensure that the labyrinth seal and flinger seal are not directly
exposed to coolant and mist.
