7. INSTALLATION AND WIRING If the AC SERVOMOTOR is subject to excessive
water or oil droplets, protect the motor with a cover.
7.1 RECEIVING The motor can withstand a small amount of splashed
This motor has been put through severe tests at the water or oil.
factory prior to shipment. After unpacking, however
check, and see the following. (3) Environmental conditions
• Its nameplate ratings meet your requirements. Ambient Temperature: 0°(2 to +40°(2
It has sustained no damage during transportation. Storage Temperature: -20°(2 to +60°C
• The output shaft should be hand-rotated freely. Humidity: 20% to 80% RH (non-condensing)
However, motors with holding brake do not rotate.
(4) Load coupling
• Fastening bolts and screws are not loose. True alignment of motor and driven machine is essen-
tial to prevent vibration, reduced bearing and coupling
If any part of the motor is damaged or lost, immedi- life, or shaft and bearing failures.
ately notify us giving full details and nameplate Use flexible couplings for direct drives. The align-
data. ment should be made in accordance with Fig. 7.2.
7.2 INSTALLATION
SE VO OZO
AC SERVOMOTOR can be installed either horizontally
or vertically.
(1) Before mounting
Wash out anticorrosive paint on shaft extension and
flange surface with thinner before connecting the motor
D to the driven machine. See Fig. 7.1.
ANTICORROSIVE
PAINT
(_) Measure the gap between a straight edge end coupling halves
at four equidistant points of the coupling. Each reading should
not exceed O.03mrn.
(_)Align the shafts.
(_Measure the gap between the coupling faces et four equidistant
points around the coupling rim with e thickness gage. The maxi-
mum variation between any two readings should not exceed
0.03mm.

Avoid shock to the motor shaft when mounting gear
(2) Location box, coupling or pulley• Don't exceed thrust and radial
loads specified in Table 4.1 to 4.3.
Use the motor under the following conditions.
• Indoors "
• Free from corrosive and/or explosive gases or liquids
• Ambient temperature: -10 to +40
• Accessible for inspection and cleaning
