Installation
This section explains the installation method of a load in addition to the
installation location and installation method of the product.
■
Installation location
Install the product in a well-ventilated location that provides easy access for
inspection.
Indoors
Operating ambient temperature: 0 to +40 °C (+32 to +104 °F) (non-freezing)
Operating ambient humidity: 85% or less (non-condensing)
Area that is free of explosive atmosphere or toxic gas (such as sulfuric gas) or
liquid
Area not exposed to direct sun
Area free of excessive amount of dust, iron particles or the like
Area free of excessive salt
Area not subject to continuous vibration or excessive shocks
Area free of excessive electromagnetic noise (from welders, power machinery,
etc.)
Area free of radioactive materials, magnetic elds or vacuum
Altitude: Up to 1000 m (3300 ft.) above sea level
Not exposed to oil (oil droplets) or chemicals.
The motor can be used in an environment that is splashed with water
(excluding the part of the connectors for driver connection and the mounting
surface of the round shaft type). Not available for use under high pressure jets
of water or immersion in water.

The gear ratio of the
BLM6300S
is 5:1 to 100:1.
The gear ratio of the
BLM6400S
is 5:1 to 50:1.
Removing and assembling the gearhead
See the following steps to replace the gearhead or to change the position of
the connector for cable connection.
Removing the gearhead from the motor
Remove the hexagonal socket head screws
(2 places) assembling the motor and
gearhead, and detach the gearhead from
the motor.
Hexagonal socket
Assembling the gearhead to the motor
1.
Keep the pilot sections of the motor and gearhead in parallel, and
assemble the gearhead with the motor while slowly rotating it
clockwise/counterclockwise. At this time, note so that the pinion of the
motor output shaft does not hit the side panel or gears of the gearhead
strongly.
Assemble the gearhead to the motor in a
condition where the motor output shaft is
in an upward direction.

2.
Check that there is no gap between the motor and gearhead, and secure
them with hexagonal socket head screws for assembling (2 pieces).

Note
Do not forcibly assemble the motor and gearhead. Also, do not
let metal objects or other foreign matter enter the gearhead.
The pinion of the motor output shaft or gear may be damaged,
resulting in noise or shorter service life.
Do not allow dust to attach to the pilot sections of the motor and
gearhead. Also, assemble the motor and gearhead carefully by
not pinching the O-ring at the motor pilot section. If the O-ring is
crushed or severed, grease may leak from the gearhead.
