2.2 Installation

Installation sites:

The servomotor SGMj type is designed for indoor use.
Install servomotor in an environment which meets the following conditions:

a) Free from corrosive and explosive gases

b) Well-ventilated and free from dust and moisture

c) Ambient temperature of 0 to 40°C

d) Relative humidity of 20% to 80% (non-condensing)

e) Inspection and cleaning can be performed easily

If the servomotor is used in a location subject to water or oil mist, the motor can be pro-
tected by taking necessary precautions on the motor side. However, if the shaft opening
is to be sealed, specify the motor with oil seal. Install with the electrical connector facing
downward.

Alignment

Align the shaft of the servomotor with that of the equipment to be controlled, then connect
the shafts with couplings. Install the servomotor so that alignment accuracy falls within
the range shown below.

Measure this distance at four different positions in the circumference. The

difference between the maximum and minimum measurements must be

0.03 mm or less. (Turn together with couplings)

NOTE

If the shafts are not aligned properly, vibration will occur, resulting in damage to the bearings.
When using a pinion gear mounted directly to the motor output shaft, contact your YASKAWA
representative.
