3 Precautions for use
This chapter explains restrictions and requirements the user should consider when using the product.
zAlways use Oriental Motor cables to connect a motor and a driver.
Refer to the cable models on p.63.
zWhen conducting the insulation resistance measurement or the dielectric strength test, be sure to
separate the connection between the motor and the driver.
Conducting the insulation resistance measurement or dielectric strength test with the motor and driver connected
may result in damage to the product.
zNote when connecting a main power supply and a control power supply in a state of grounding the
positive side
The USB communication connector, CN1, CN2, and CN3 connectors on the driver are not electrically insulated. When
grounding the positive terminals of a main power supply and a control power supply, do not connect any equipment
(PC, etc.) whose negative terminal is grounded. Doing so may cause the driver and this equipment to short, damaging
both. When connecting, do not ground equipment.
zSaving data to the non-volatile memory
Do not turn o the control 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.
zNoise elimination measures
Refer to p.20 for the noise elimination measures.
zRegeneration
When operating a large load inertia at a high speed, the regenerative energy generated may increase the voltage of
the main power supply, causing an alarm of the overvoltage to generate. To prevent damage to the driver, reconsider
the operating conditions so that regenerative voltage does not generate.
Notes when the connection cable is used
Note the following points when an Oriental Motor cable is used.
zWhen inserting the connector
Hold the connector main body, and insert it in straight securely. Inserting the connector in an inclined state may result
in damage to terminals or a connection failure.
zWhen pulling out the connector
Pull out the connector in straight while releasing the lock part of the connector. Pulling out the connector with
holding the cable may result in damage to the connector.
zBending radius of cable
Use the cable in a state where the bending radius of the cable is more than
6 times of the cable diameter.
Do not bend the lead wires part or secure with a clamp, etc. Doing so may
result in damage to the connector.
More than 6 times
of cable diameter.
Do not bend the
lead wires part.

Precautions for use

6-4 Connecting the USB cable
Using a USB cable with the following specications, connect a PC in which the MEXE02 has been installed to the USB
communication connector.
Specications USB2.0 (Full speed)
Cable Length: 3 m (9.8 ft.) or less
Shape: A to mini B
•Connect the driver and a PC directly using a USB cable.
•In large electrically noisy environments, use the USB cable with a ferrite core or install a ferrite core
to the USB cable.
6-5 Noise measures
There are two types of electrical noises: One is a noise to invade into the driver from the outside and cause the driver
malfunction, and the other is a noise to emit from the driver and cause peripheral equipment malfunction.
For the noise that is invaded from the outside, take measures to prevent the driver malfunction. It is needed to take
adequate measures because signal lines are very likely to be aected by the noise.
For the noise that is emitted from the driver, take measures to suppress it.
Measures against electrical noise
There are the following three methods mainly to take measures against the electrical noise.
zNoise suppression
•When relays or electromagnetic switches are used, use noise lters or CR circuits to suppress surge generated by
them.
•Use an Oriental Motor connection cable when extending the wiring distance between a motor and a driver. Refer
to p.63 for the model name. This is eective in suppressing the electrical noise emitted from the motor.
•Cover the driver by a metal plate such as aluminum. This is eective in shielding the electrical noise emitted from
the driver.
zPrevention of noise propagation
•Connect a noise lter on the input side of the DC power supply.
•Place the power lines, such as the motor and power supply cables, keeping a distance of 200 mm (7.87 in.) or more
from the signal lines, and also do not bundle them or wire them in parallel. If a power cable and a signal cable have
to cross, cross them at a right angle.
•Use shielded twisted pair cables for power lines and signal lines.
•Keep cables as short as possible without coiling and bundling extra lengths.
•Grounding multiple points will increase eect to block electrical noise because impedance on the grounding
points is decreased. However, ground them so that a potential dierence does not occur among the grounding
points.
•To ground a shielded cable, use a metal cable clamp that can maintain
contact with the entire circumference of the shielded cable, and ground
as near the product as possible.

zSuppression of eect by noise propagation
•Loop the noise propagated cable around a ferrite core. Doing so will prevent the propagated noise invades into
the driver or emits from the driver. The frequency band in which an eect by the ferrite core can be seen is
generally 1 MHz or more. Check the frequency characteristics of the ferrite core used. When increasing the eect of
noise attenuation by the ferrite core, loop the cable a lot.
