DO NOT DISASSEMBLE
Do not disassemble the motor unit. There is a risk that the machine can be broken due to abnormal operation.
CAUTION
Never give shocks to the encoder, motor and shaft extension, for example by hitting them with a hammer etc.
In addition, be careful not to apply a load to the encoder during installation.
(5) Mechanical coupling
(a) Motor with flexible coupling
(i) Provide a reference mark on the peripheral surface of the
coupling.
(ii) Connect both halves of the coupling with a single-bolt, in order to
allow them to rotate together.
(iii) Attach a dial gauge securely to one half of the coupling so that
its feeler rests lightly on the other half.
(iv) Bring the reference mark to the top of the coupling and, then,
measure dimension “g” with a thickness gauge and dimension “h”
with a dial gauge.
(v) Turn the coupling and carry out the measurements described in (iv)
above at 90
°
intervals until the reference mark appears at the top
again.
(vi) Conduct adjustments so that the difference between the
maximum and the minimum measurements is held to within
0.03mm. Be sure to bolt the motor and driven machine to the base
prior to marking adjustments.
If a coupling is too small to allow a dial gauge to be attached to it,
attach a stretch (rectangular steel bar) to one half of the coupling
and measure the clearance value of the stretch and the surface of
the other half of the coupling.
(b) Motor for extemal gear drive
If a gear drive is used, the shafts of both machines should be
exactly parallel, to avoid subjecting the gear teeth to an excessive
load at the contact points.
(c) Motor for timing belt connection
When using a timing belt, obtain necessary data from the belt
supplier, and contact Fuji.
(6) Power supply to motor
CAUTION
Do not connect commercial power supply to the motor terminals.
(7) Dimensional tolerances
Tolerances of motor at the time of shipment from the factory are as follows.
The maximum and minimum values throgh one slow revolution of the shaft are then read on the indicator.
The difference between the readings will not exceed the values given in the following table.
(a) Shaft extension run-out
The probe of the indicator is attached to the shaft midway along its length.
(b) Concentricity of spigot and the shaft for flange-mounted motor
The indicator is fitted rigidly on the shaft extension.
