• The motor and driver should be firmly secured on the metallic plate in order to prevent personal injury and
damage to the equipment.
• The rotating part (output shaft) of the motor (gearhead) should be provided with a cover. Otherwise, injury
may occur.
• Do not allow your finger to be caught between the equipment and motor or gearhead when installing the
motor with or without gearhead on the equipment. Otherwise, injury may occur.
Operation
• Use the motor and driver in it‘s specified combination. This is to prevent fire.
• Provide an emergency-stop device or emergency-stop circuit external to the equipment so that the entire
equipment will operate safely in the event of a system failure or malfunction. Failure to do so may result in
injury.
• To prevent bodily injury, do not touch the rotating parts (output shaft) of the motor during operation.
• Immediately when trouble has occurred, stop running and turn off the driver power. Failure to do so may
result in fire, electric shock or injury.
• To prevent electric shock, use only an insulated screwdriver to adjust the internal switches.
• The motor’s surface temperature may exceed 70 °C (158 °F), even under normal
operating conditions. If a motor is accessible during operation, post a warning label
shown in the figure in a conspicuous position to prevent the risk of skin burn(s).

3 Precautions for use
−6 −
3 Precautions for use
This section covers limitations and requirements the user should consider when using the BX series.
 Connect protective devices to the power line
Connect a circuit breaker or earth leakage breaker to the driver’s power line to protect the primary circuit. If
an earth leakage breaker is to be installed, use one incorporating high-frequency noise elimination measures.
Refer to 10.2, “Recommended peripherals” on page 46 for the selection of appropriate protective devices.
 Use an electromagnetic brake motor for an application involving
up/down travel.
When the motor is used in an application involving up/down travel, use an electromagnetic brake motor to
hold the load in position. To hold the load in position, apply the electromagnetic brake only after the motor
has stopped. Do not use the brake to bring the moving motor to a halt. Repeated braking for such a purpose
will wear the brake hub excessively, causing its holding ability to drop.
Since the electromagnetic brake is of the non-excitation type, it can also be used to hold the load in position
upon the occurrence of a power failure. However, this is not a secure means of holding the load. Do not use
the electromagnetic brake as a safety brake.
 Use a regeneration unit (sold separately) for vertical drive
applications and those involving high inertial loads.
The driver may be damaged if the energy that is regenerated during a vertical (gravitational) operation or due
to an abrupt start/stop involving a large inertial load exceeds the maximum level that can be absorbed by the
driver. The optional regeneration unit (sold separately) is designed to discharge the regenerated energy,
thereby protecting the driver.
 Do not use a solid-state relay (SSR) to turn on/off the power
A circuit that turns on/off the power via a solid-state relay (SSR) may damage the motor and driver.
 Conduct the insulation resistance measurement or withstand voltage
test separately on the motor and the driver.
Conducting the insulation resistance measurement or withstand voltage test with the motor and driver
connected may result in injury or damage to equipment.
 Do not conduct insulation resistance test or withstand voltage test
on the encoder.
These tests may damage the encoder.
 Grease measures
On rare occasions, a small amount of grease may ooze out from the geared motor. If there is concern over
possible environmental damage resulting from the leakage of grease, check for grease stains during regular
inspections. Alternatively, install an oil pen or other device to prevent leakage from causing further damage.
Oil leakage may lead to problems in the customer’s equipment or products.
 Apply grease on the hollow-shaft flat gearhead output shaft
If you are using a hollow-shaft flat gearhead, apply grease (molybdenum disulfide grease, etc.) on the surface
of the load shaft and inner walls of the hollow output shaft to prevent seizure.

3 Precautions for use
−7 −
 Measures against noise
To prevent possible driver and motor operation errors due to external noise, take the following measures
against noise:
• Electrical connection of the motor
For electrical connection of the driver and motor, use an optional extension cable.
• Electrical connection of input/output signal cable
• Connect the input/output signal cable in the shortest possible distance.
• Connect the input/output signal cable 100 mm (4 in.) or more away from the induction load such as
electromagnetic relay and current carrying cables (for power supply, motor, etc.). Do not connect it together
with the current carrying cable, for example, by routing them together through the same duct or conduit.
• Furthermore, use the braided-screen cable as the input/output signal cable. When the braided-screen cable
cannot be used, it will be effective to install a Ferrite core on each of the controller and driver sides.
• Connection of mains filter for power supply line
To prevent external noise from being transferred through the power line, connect a mains filter to the driver
AC power supply line input section. Ground the mains filter ground terminal using a cable with a diameter of
equivalent to AWG18 (0.75 mm2) or greater.

5.6 Installing a load on the combination-type parallel gearhead or
round-shaft type
When installing a load on the motor (gearhead), align the center of the motor output shaft (gearhead output
shaft) with the center of the load shaft.
Note • When coupling the motor (gearhead) with a load, pay attention to centering, belt
tension, parallelism of pulleys, etc. Also, securely affix the tightening screws of the
coupling or pulleys.
• When installing a load, do not damage the motor output shaft (gearhead output shaft) or
bearing. Forcing in the load by driving it with a hammer, etc., may break the bearing. Do
not apply any excessive force to the output shaft.
• Do not modify or machine the motor (gearhead) output shaft. The bearing may be
damaged or motor (gearhead) may break.
 Output shaft shape
• Combination-type parallel-shaft gearhead
A key groove is provided on the output shaft of each combination-type parallel-shaft gearhead. Form a key

On the GFS6G, the parallel key is affixed to the gearhead output shaft.
• Round-shaft type
A flat section is provided on the motor output shaft of each round-shaft motor. Apply a double-point screw,
etc., at the flat section to securely affix the load and prevent it from spinning.
 How to install a load
• Using a coupling
Align the centerline of the motor (gearhead) output shaft with the centerline of the load shaft.
• Using a belt
Adjust the motor (gearhead) output shaft to lie parallel with the load shaft and form right angles between the
output shaft/load shaft and the line connecting the centers of both pulleys.
• Using a gear
Adjust the motor (gearhead) output shaft to lie parallel with the gear shaft and allow the output shaft to mesh
correctly with the centers of the gear teeth.
• Using the output axis tip screw hole of a gearhead
Use a screw hole provided at the tip of the output shaft as an auxiliary means for preventing the transfer
mechanism from disengaging. (GFS2Gtype have no output shaft tip screw hole.)

5.7 Installing a load on the combination-type hollow-shaft flat gearhead
If the motor is subject to a strong impact upon instantaneous stop or receives a large overhung load, use a
stepped load shaft.
Note • Apply grease (molybdenum disulfide grease, etc.) on the surface of the load shaft and
inner walls of the hollow output shaft to prevent seizure.
• When installing the load shaft using an end plate, the safety cover (supplied) cannot be
attached due to contact between the safety cover and hexagonal socket head screw.
Take safety measures against rotating part.
