System Design
Servomotor Installation Conditions
Environment Operating Conditions
The environment in which the motor is operated must meet the following conditions. Operating the
motor out of the following ranges may result in malfunction of the motor.
Operating ambient temperature: 0 to
40
C
*1
Operating humidity: 85% RH max. (with no condensation)
Operating atmosphere: No corrosive gases.
*1. The operating ambient temperature is the temperature at a point 5 cm from the motor.
Impact and Load
The motor is resistant to impacts of up to 98 m/
s
2
. Do not apply heavy impacts or loads during
transport, installation, or removal of the motor.
When transporting, hold the motor body
itself. And do not hold the encoder, cable, or
connector areas. Failure to follow this
guideline may result in damaging the motor.
Always use a pulley remover to remove pulleys,
couplings, or other objects from the shaft.
After assembly, secure cables so that there
is no impact or load placed on the cable
outlet.
Connecting to Mechanical Systems
For the allowable axial loads for motors,
refer to "Characteristics"(P.3-2). If an axial
load greater than that specified is applied to
a motor, it may reduce the limit of the motor
bearings and may break the motor shaft.
When connecting to a load, use couplings
that can sufficiently absorb mechanical
eccentricity and declination.
For spur gears, an extremely large radial load
may be applied depending on the gear precision.
Use spur gears with a high degree of precision
(for example, JIS class 2: normal line pitch error
of 6
m max. for a pitch circle diameter of 50 mm).
If the gear precision is not adequate, allow
backlash to ensure that no radial load is
placed on the motor shaft.
When using bevel gears, a load is applied in the
thrust direction depending on the structural
precision, the gear precision, and temperature
changes. Provide appropriate backlash or take
other measures to ensure that a thrust load
larger than the specified level is not applied.
Do not put rubber packing on the flange
surface. If the flange is mounted with rubber
packing, the motor flange may crack under
the tightening force.
Set a movable structure.
Bevel gear
Set a structure in which
the distance between
axes can be adjusted.
