3 Precautions for use
This section covers restrictions and requirements the user should consider when using the product.
Wiring
zConnecting a motor and a driver
Use the dedicated connection cable (sold separately) when extending the wiring distance between the motor and the
driver.
zNotes when the cable is used
Note the following points when the cable is used.
How to x the cable
Fix the cable at the positions near the connector so that no stress due to the bending or self-weight of the cable is
applied on the connector.
Also, do not excessively bend the cable near the connection part of the connector. Applying stress on the cable may
cause poor contact or disconnection, leading to malfunction or heat generation.

•Fixing at two places on each side •Fixing at one place on each side
A wide clamp is also
available to use.
Connector
Banding band, etc
.
Connector
Banding band, etc.
Fix using two cable ties or a wide clamp. When the cable is moved, it causes the connectors to
move, causing stress to apply on the connector part.
When bending the cable
Do not excessively bend the cable.
Applying stress on the cable may cause poor contact or disconnection, leading to
malfunction or heat generation.
Do not bend ex
cessively
zNote when connecting a power supply whose positive terminal is grounded
The USB connector on the driver is not electrically insulated. When grounding the positive terminal of the power
supply, do not connect any equipment (PC, etc.) whose negative terminal is grounded. Doing so may cause the driver
and these equipment to short, damaging both.
zNoise elimination measures
Refer to p.33 for noise elimination measures.

Precautions for use
7
Installation
zGrease measures
On rare occasions, grease may ooze out from the gearhead. If there is concern over possible environmental
contamination resulting from the leakage of grease, check for grease stains during regular inspections. Alternatively,
install an oil pan or other device to prevent damage resulting from contamination. Grease leakage may lead to
problems in the user’s equipment or products.
zWhen using in low temperature environment
When an ambient temperature is low, a load torque may increase due to the oil seal or viscosity increment of grease
used in the gearhead, and the output torque may decrease or the overload alarm may be generated. However, as time
passes, the oil seal or grease is warmed up, and the motor can be operated without generating the overload alarm.
zApply grease to the hollow output shaft of a hollow shaft at gearhead.
When using a hollow shaft at gearhead, apply grease (molybdenum disulde grease, etc.) on the surface of the load
shaft and inner walls of the hollow output shaft to prevent seizure.
Insulation resistance measurement and dielectric strength test
zDo not conduct the insulation resistance measurement or the dielectric strength test with the motor
and driver connected.
Conducting the insulation resistance measurement or dielectric strength test with the motor and driver connected
may result in damage to the product.
Operations
zRegeneration energy
When the motor is used in operation such as rapid acceleration/deceleration of an inertia body or vertical drive
(elevating equipment), regeneration energy may generate. Since the driver has no function to consume regeneration
energy, if the output capacity or overvoltage allowance of the DC power supply is small, the protective function for
the power supply or driver may be activated to stop the motor. When performing these operations, use a DC power
supply or battery that has a large output capacity or overvoltage allowance.
If the protective function for the power supply or driver is activated, contact your nearest Oriental Motor sales oce.
zUse an electromagnetic brake motor in an application of vertical drive such as elevating equipment.
When the motor is used in an application of vertical drive such as elevating equipment (lifting and lowering device),
use an electromagnetic brake motor so that the load can be held in position.
zThe electromagnetic brake of the motor is used for holding the motor shaft. Actuating the
electromagnetic brake to hold the motor shaft while the motor is rotating may result in damage to
equipment.
zRotation direction of the gearhead output shaft
Combination type-parallel shaft gearhead
The rotation direction of the gearhead output shaft may vary with that of the motor output shaft depending on the
gear ratio of the gearhead.
Gear ratio Rotation direction of the gearhead output shaft
10, 15, 20 Same direction as the motor output shaft
30, 50, 100* Opposite direction to the motor output shaft
* Same direction as the motor output shaft when the gear ratio is 100 for the 200 W type

Precautions for use
8
Combination type-hollow shaft at gearhead
The rotation directions of the gearhead output shaft relative to the motor output shaft are as shown in the gures
below.
Motor output shaft Gearhead output shaft
Front Rear
zSliding noise of electromagnetic brake
Sliding noise of the brake disk for the electromagnetic brake motor may be generated during operation.
It is no functional problem.
Power removal function
zIf the power removal function is activated, the motor holding force is lost and the motor output shaft
may be rotated by external forces (gravity on a vertical axis, etc.). If the motor output shaft is required
to hold in position, install an external brake mechanism or equivalent. Failure to do so may result in
injury or damage to equipment.
zThe power removal function is a function to shut o the power supply to the motor by stopping
operation of the inverter circuit. It is not a function to physically shut o the driver and the motor.
When touching the driver or the motor, turn o the driver power and check the PWR/SYS LED is turned
o. Failure to do so may result in electric shock.
zBe sure to check the motor is in a standstill state before transitioning to the power removal status.
Transitioning to the power removal status while the motor is rotating may cause damage to the motor,
driver, or equipment.
Saving the data
zNotes when saving the data to the non-volatile memory
Do not turn o the power supply while writing the data to the non-volatile memory, and also do not turn o for ve
seconds after the completion of writing the data. Doing so may abort writing the data and cause an alarm of EEPROM
error to generate.
The non-volatile memory can be rewritten approximately 100,000 times.

•Do not forcibly assemble the motor and gearhead. Also, prevent metal objects or foreign substances from
entering in 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.

zRemoving and assembling the gearhead
See the following steps to replace the gearhead or to change the cable outlet position.
However, when the motor which cable outlet direction is the output shaft side (the end of the motor model name is F)
is used, it cannot be installed in the direction where the motor cable faces the hollow output shaft side.
1. Removing the gearhead from the motor
Remove the hexagonal socket head screws (4 places) assembling the
motor and gearhead, and detach the gearhead from the motor.
2. 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.
Change the cable
position to a desired
90° direction.
2) Check that there is no gap between the motor and the gearhead, and tighten them with hexagonal socket
head screws (4 places).

Do not install the motor to the mounting hole diagonally or assemble the motor forcibly. Doing so may cause
damage to the ange pilot section, thereby resulting in damage to the motor.
5-3 Installing a load
Combination type-parallel shaft gearhead, round shaft type
When installing a load on the motor or the gearhead, pay attention to the following points.
•Align the center axis of the motor output shaft or the gearhead output shaft with that of the load.
•A key slot is provided on the output shaft of each combination type-parallel shaft gearhead. Form a key slot on the
load side and secure the load using the parallel key.
•When coupling the motor or the gearhead with a load, pay attention to centering, belt tension, parallelism of
pulleys, etc. Also, rmly secure the tightening screws of the coupling or pulleys.
•When installing a load, do not damage the motor output shaft (gearhead output shaft) or bearings. Installing
the load forcibly with a hammer or the like may break the bearings. Do not apply any excessive force to the
output shaft.
•Do not modify or machine the output shaft of the motor or gearhead. This may damage the bearing, resulting
in damage to the motor or gearhead.
When using the output shaft end tapped hole of a gearhead
Use a tapped hole provided at the end of the output shaft as an auxiliary
means for preventing the transfer mechanism from disengaging. Fixed scre
