4-1 Installation Conditions

Servomotors

 Operating Environment
 The environment in which the Servomotor is operated must meet the following conditions.
Operating the Servomotor outside of the following ranges may result in malfunction of the
Servomotor.
Note The ambient temperature is the temperature at a point 5 cm from the Servomotor.
4
 Impact and Load
 The Servomotor is resistant to impacts of up
to 98 m/s
loads during transport, installation, or
removal.
 When transporting, hold the Servomotor
body itself, and do not hold the encoder,
cable, or connector areas. Doing so may
damage the Servomotor.
 Always use a pulley remover to remove
pulleys, couplings, or other objects from the
shaft.
 Secure cables so that there is no impact or
load placed on the cable connector areas.
 Connecting to Mechanical Systems
 The axial loads for Servomotors are
specified in Characteristics on page 3-18. If
an axial load greater than that specified is
applied to a Servomotor, it will reduce the
service life 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.
 Bevel gears will cause a load to be 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.
