■ Oil and Water Countermeasures
It is possible to take protective measures for motor operation in areas where water or oil
may drip. However, use a motor with an oil seal attached when needed to set through to
the shaft section
1
. In addition, mount the motor with the connectors facing downward.
■ Cable Stress
Do not bend or stretch the power line.
In particular, be careful to wire the signal cable so that they are not subject to stress
because its core is very thin (0.2, 0.3mm).
