Precautions for use
 Regeneration energy
When using the motor in operation such as vertical drive (gravitational
operation) or sudden starting/stopping of an inertial load, 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
activate, and the motor may stop. When performing these operations, use a
DC power supply or battery that has a large output capacity or overvoltage
allowance. Also, use an electromagnetic brake motor not to drop the moving
part in vertical drive (gravitational operation).
If the protective function for the power supply or driver is activated, contact
your nearest Oriental Motor sales oce.
 Do not conduct the insulation resistance measurement or 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.
 Do not use a solid-state relay (SSR) to turn on/o󰀨 the power
A circuit that turns on/o the power via a solid-state relay (SSR) may damage
the motor and driver.
 Notes for power ON/OFF using a mechanical contact
When turning on or o the power supply using a mechanical contact (breaker,
electromagnetic switch, relay, etc.), do so only the positive side (+) of the
power supply using the mechanical contact. Turning on or o the positive
side (+) and the negative side (-) of the power supply simultaneously using
a mechanical contact may cause damage to the control circuit or peripheral
equipment.
Refer to USER MANUAL Basic Function for details.
 Note on connecting a power supply whose positive terminal is
grounded
The driver's main power supply input terminal (CN1), I/O signal connector
(CN4), communication connector (CN5/CN6/CN7) and control power supply
input terminal (TB1) are 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.
 Preventing electrical noise
Refer to USER MANUAL Basic Function for measures with regard to noise.
 Grease measures
On rare occasions, grease may ooze out from the gearhead. 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 pan or other device to prevent leakage from causing further damage. Oil
leakage may lead to problems in the customer’s equipment or products.
 Note on using in low temperature environment
When an ambient temperature is low, a load torque may increase due to the
oil seal or viscosity of grease used in the gearhead, and the output torque
may decrease or an overload alarm may generate. However, as time passes,
the oil seal or grease is warmed up, and the motor can be operated without
generating the overload alarm.
 Apply grease to the output shaft of a hollow shaft at gearhead
If you are 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.
 The driver uses semiconductor elements. Handle the driver with
care
The driver uses parts that are sensitive to electrostatic charge. Before touching
the driver, turn o the power to prevent electrostatic charge from generating. If
an electrostatic charge is impressed on the driver, the driver may be damaged.
 Use a connection cable (included) when extending the wiring
distance between the motor and driver
 Sliding noise of electromagnetic brake
An electromagnetic brake motor may cause a sliding noise of the brake disk
during operation. There is no functional problem.

 Installing the driver
The driver is designed so that heat is dissipated via air convection and
conduction through the enclosure. Install the driver on a at metal plate
having excellent vibration resistance and heat conductivity.
When two or more drivers are to be installed side by side, provide 20 mm (0.79
in.) and 25 mm (0.98 in.) clearances in the horizontal and vertical directions,
respectively.
Note
Install the driver in an enclosure whose pollution degree is
2 or better environment, or whose degree of protection is
IP54 minimum.
Do not cover the radiation vent of the driver.
Do not install any equipment that generates a large
amount of heat or noise near the driver.
If the ambient temperature of the driver exceeds 40 °C
(104 °F), revise the ventilation condition or force-cool the
area around the driver using a fan.
zMounting to DIN rail
When mounting the driver to a DIN rail, use the DIN rail mounting plate
PADP03 (sold separately) and attach it to a 35 mm (1.38 in.) wide DIN
rail. After installation, x the both sides of the driver with the end plate (not
included).
