The standard receptacle connectors for models β1 to β6 do not
exactly satisfy the MS standard in that the connectors are waterproof
as single units, and their exterior color is black. However, their sizes
and shapes are compatible with the conventional round-type
connectors conforming to the MS standard.
Accordingly, in addition to the products recommended below, plug
connectors conforming to the MS standard can also be used. (When
the water-resistance of the system is of prime importance, the
waterproof plug connectors recommended.
WARNING
Direct motor connectors downwards whenever
possible. When a motor connector must be
directed horizontally, provide sufficient cable slack
to prevent, for example, the connector from being
wetted by liquid such as coolant. The connectors
on the βM0.2 to βM0.3 motors are not water-proof.
The machine tool builder is requested to make
some provision to protect the connectors from
water and moisture. In any case, if a motor
connector is exposed to liquid, protection by means
of a cover, for example, must be provided.
CAUTION
If the motor in not grounded via the machine
(cabinet) on which it is mounted, connect a wire
between the terminal to which the motor ground
cable is connected and that to which the amplifier
ground cable is connected, to suppress noise. In
such a case, use a wire of at least 1.25mm
2
,
independently of the ground wire within the power
cable, and route it as far away from the power
cable as possible.
