Precautions for use
3 Precautions for use
This chapter covers limitations and requirements the user should consider when using the product.
Be sure to match the output power of the driver with that of the motor when using.
zDo not perform gravitational operation (vertical drive).
If the
load side, the inverter voltage of the driver will exceed the permissible value, and the alarm function will be activated to
cause the motor to coast to a stop. If this happens, there is a possibility that the load will drop.
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.
zApply grease to the hollow output shaft of a hollow shaft at gearhead.
Apply grease (molybdenum disulde grease, etc.) on the surface of the load shaft and the inner walls of the hollow
output shaft to prevent seizure.
zDo 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.
Series is used in operation (i.e. gravitational operation) in which the motor output shaft is turned from the
BLH
zNoise elimination measures
Refer to p.13 for the noise elimination measures.
zNote on 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.
zNotes about when saving the data to the non-volatile memory
Do not turn o the 24 VDC power supply while writing the data to the non-volatile memory, and also do not turn o
within 5 seconds after the completion of writing the data. Doing so may abort writing the data and cause a EEPROM
error alarm to generate.
The non-volatile memory can be rewritten approximately 100,000 times.

6.9 Noise measures
Cable cramp
Shielded cable
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 equipments 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 aected 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 a connection cable (sold separately) when extending the wiring distance between the motor and the driver.
This is eective in suppressing the electrical noise emitted from the motor.
•Cover the driver by a metal plate such as aluminum. This is eective in shielding the electrical noise emitted from the
driver.
zPrevention of noise propagation
•Separate power lines such as motor cable and power supply cable from signal lines for a distance of 100 mm (3.94 in.)
or more, and also do not bundle them or wire them in parallel. If the power lines must cross over the signal lines, wire
them at right angles.
•Use a cable of AWG26 (0.14 mm
or less.
•For more eective elimination of noise, use shielded cables for a power supply cable and I/O signal cable, or attach
ferrite cores if non-shielded cables are used.
•Keep cables as short as possible without coiling and bundling extra lengths.

) or thicker for the signal cable of the driver, and keep the wiring distance of 3 m (9.8ft.)
•Grounding multiple points will increase eect to block electrical noise because impedance on the grounding points is
decreased.
However, ground them so that a potential dierence does not occur among the grounding points.
zSuppression of eect 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 eect 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 eect of noise
attenuation by the ferrite core, loop the cable a lot.
6.10 Conformity to the EMC Directive
Eective measures must be taken against the EMI that the motor and driver may give to adjacent control-system
equipment, as well as the EMS of the motor and driver itself, in order to prevent a serious functional impediment in the
machinery. The use of the following installation and wiring methods will enable the motor and driver to be compliant
with the EMC directive. Refer to p.27 for the applicable standards.
Oriental Motor conducts EMC measurements on its motors and drivers in accordance with "Example of installation and
wiring" shown on the next page.
The user is responsible for ensuring the machine’s compliance with the EMC Directive, based on the installation and
wiring explained below.

Use 7427122 (Würth Elektronik GmbH & Co.KG), ZCAT3035-1330 (TDK Corporation) or equivalent ferrite cores.
Install the ferrite core as close as possible to the driver.
Wiring the I/O signal cable
Refer to "Prevention of noise propagation" on p.13.
Notes about installation and wiring
•Connect the motor, driver and other peripheral control equipment directly to the grounding point so as to prevent a
potential dierence from developing between grounds.
•When relays or electromagnetic switches are used together with the system, use noise lters and CR circuits to
suppress surges generated by them.
•Keep a power supply cable and signal cable as short as possible without coiling and bundling extra lengths.
•Separate power lines such as motor cable and power supply cable from signal lines, and wire them apart as much
as possible [example: about 100 to 200 mm (3.94 to 7.87 in.)]. If the power lines must cross over the signal lines, wire
them at right angles.

7.6 Multi-motor control
Operating two or more motors at the same speed can be performed using any of the external potentiometer, external
DC voltage, or PWM signal.
Using an external potentiometer
Use common lines for the power supply and speed setting, and set the speed using VRx as shown in the gure below.
•Obtain the resistance value for the external speed potentiometer as follows.
Resistance VRx when the number of drivers is n units: VRx (kΩ) = 20 kΩ/n, permissible dissipation (W) = n/20
Example: If two drivers are connected, 10 kΩ and 1/10 W are obtained.
•For I/O signals other than the speed setting, connect for each driver.
•If multiple motors are used with speed dierences among them, adjust as follows.
The rst driver: Connect a resistor of 1.5 kΩ, 1/20 W to the terminal M on the driver.
The second and subsequent drivers: Connect a variable resistor (VRn) of 5 kΩ, 1/20 W to the terminal M on the driver.
