3.3 Mechanical Specifications of Servomotors
3.3.1 Precautions on Servomotor Installation
Servomotors can be installed either horizontally or vertically.
The service life of the servomotor will be shortened or unexpected problems will occur if the servomotor is
installed incorrectly or in an inappropriate location. Always observe the following installation instructions.
• Do not connect the servomotor directly to a commercial power line. This
will damage the servomotor.
The servomotor cannot operate without the proper SERVOPACK.
CAUTION
Do not connect
Storage
Temperature
and Humidity
Store the servomotor within the following temperature range if it is stored with the power cable discon-
nected.
Surrounding air temperature during storage: -20 to 60
°
C
Ambient humidity during storage: 80%RH or less (with no condensation)
Installation Site
Servomotors are designed for indoor use. Install the servomotor in environments that satisfy the follow-
ing conditions.
• Free of corrosive or explosive gases.
• Well-ventilated and free of dust and moisture.
• Surrounding air temperature of 0 to 40
°
C
• Relative humidity of 20% to 80% with no condensation.
• Facilitates inspection and cleaning
Alignment
Align the shaft of the servomotor with the shaft of the
equipment, and then couple the shafts. Install the servo-
motor so that alignment accuracy falls within the range
described on the left.
Vibration may occur and damage the bearings and the
encoder if the shafts are not correctly aligned.
Connect the servomotor to a machine in a way that pre-
vents the application of concentric loads or rotary unbal-
anced loads on the motor shaft.
When installing, do not hit
the shafts with a hammer
etc., as impacts may result
in malfunction.
Orientation
Servomotors can be installed either horizontally or vertically.
Measure this distance at four
different positions on the
circumference. The difference
between the maximum and
minimum measurements must be
0.06 mm or less.
(Turn together with coupling.)
Alignment Accuracy
Measure this distance at four
different positions on the
circumference. The difference
between the maximum and
minimum measurements must be
0.05 mm or less.
(Turn together with coupling.)
