Sigma II User’s Manual Chapter 2: Installation
2 - 6
2.1.7 Vibration Class
The vibration class for SGMH servomotors operating at rated speed is 15μm
(maximum).
2.1.8 Handling Oil and Water
Install a protective cover over the servomotor if it is used in a location that is subject
to water or oil mist. Also use a servomotor with an oil seal when needed to seal the
through-shaft section.
Install the servomotor with the connector facing down.
Note: Through sections of the shaft: This refers to the gap where the shaft protrudes from the end of the
motor
2.1.9 Cable Stress
Make sure that the power lines are free from bends and tension.
Be especially careful to wire signal line cables so that they are not subject to stress
because the core wires are very thin, measuring only 0.0079 to 0.012in (0.2 to
0.3mm).
