 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.

zz Do not perform gravitational operation (vertical drive).

If the BLH Series is used in operation (i.e. gravitational operation) in which the motor output shaft is turned from the
load side, the motor speed cannot be controlled. In addition, a gravitational load operation will cause the driver’s
primary inverter voltage to exceed the allowable value, thereby triggering a protection function and causing the motor
to stop spontaneously. If this happens, there is a possibility that the load will drop.
zz Do not conduct the insulation resistance measurement or the dielectric strength test with the motor and
driver connected.
Conducting the insulation resistance measurement or the dielectric strength test with the motor and driver connected
may result in damage to the product.
zz Note on power ON/OFF using a mechanical contact
When turning on or off 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 off 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 p.9 for details.
zz Noise elimination measures
Refer to p.13 for the noise elimination measures.
zz Grease 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.
zz Apply grease to the hollow output shaft of a hollow shaft flat gearhead.
Apply grease (molybdenum disulfide grease, etc.) on the surface of the load shaft and the inner walls of the hollow
output shaft to prevent seizure.
zz Sliding 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.

 Connection

6.7 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 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 affected 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.
zz Noise suppression
•• When relays or electromagnetic switches are used, use noise filters 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 effective in suppressing the electrical noise emitted from the motor.
•• Cover the driver by a metal plate such as aluminum. This is effective in shielding the electrical noise emitted from the
driver.
zz Prevention 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.
2
•• Use a cable of AWG26 (0.14 mm ) or thicker for the signal cable of the driver, and keep the wiring distance of 3 m (9.8 ft.)
or less.
•• For more effective elimination of noise, use shielded 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.
•• To ground a shielded cable, use a metal cable clamp that can Shielded cable
maintain contact with the entire circumference of the shielded
cable, and ground as near the product as possible. Cable cramp

•• Grounding multiple points will increase effect to block electrical noise because impedance on the grounding points is
decreased. However, ground them so that a potential difference does not occur among the grounding points.
zz Suppression of effect 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 effect 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 effect of noise
attenuation by the ferrite core, loop the cable a lot.

6.8 Conformity to the EMC Directive

This product has been designed and manufactured to be incorporated in equipment. The EMC Directive requires that
your mechanical equipment in which the product is installed satisfies the applicable requirements. The installation/
wiring methods of the motor and driver explained here represent the basic methods that are effective in helping your
mechanical equipment conform to the EMC Directive. The final level of conformance of your mechanical equipment
to the EMC Directive will vary depending on such factors as the control system equipment used with the motor/driver,
configuration of electrical parts, wiring, layout and hazard level. It therefore must be verified through conducting EMC
measures on your mechanical equipment.

Without effective measures to suppress the electromagnetic interference (EMI) caused by the product in the
surrounding control system equipment or the electromagnetic spectrum (EMS) generated by the product, the function
of your mechanical equipment may be seriously affected.
This product will conform to the EMC Directive if installed/wired using the methods specified below.

About power supply

„„
The BLH Series is a product of DC power supply input. Use a DC power supply (such as a switching power supply) that
optimally conforms to the EMC Directive.

Connecting the motor cable

„„
When extending the motor cable, use an connection cable (sold separately). The maximum extension distance including
the cable length of the motor itself should be 2 m (6.6 ft.).

13
Connection

Ferrite core
„„
Use a ferrite core to suppress effect by noise propagation.
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 difference from developing between grounds.
•• When relays or electromagnetic switches are used together with the system, use noise filters and CR circuits to
suppress surges generated by them.
•• 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.

 Operation

7 Operation
7.1 Input signals and output signals
Do not perform the motor’s starting and stopping operations by turning the power supply
CAUTION on and off. Perform them by inputting START/STOP and RUN/BRAKE. This may cause injury or
damage to the equipment.

Note •• The input signals (START/STOP, RUN/BRAKE, CW/CCW, INT.VR/ EXT, ALARM-RESET) must be ON for at least 10 ms. It
may cause malfunction of the motor.
•• Do not operate (switch the ON/OFF status) of the START/STOP input, RUN/BRAKE input, CW/CCW input and INT.VR/
EXT input simultaneously. After switching a given input, wait at least 10 ms before switching another input.
•• The motor temperature rise is sharper as friction load and inertial load are higher, and start, instantaneous stop and
reversing frequency is higher. It must be used when motor case temperature does not exceed 90 °C (194 °F), and
driver heat radiation plate temperature does not exceed 90 °C (194 °F).

START/STOP input and RUN/BRAKE input

 Operation

7.3 Setting the running speed

Set the operating speed of the motor using the internal speed potentiometer, external speed potentiometer or external
DC voltage. The motor speed range is from 100 to 3000 r/min for the case of the motor alone.
Two running speeds can be set by combining the internal potentiometer and external potentiometer, or the internal
potentiometer and external DC voltage.

Setting by internal potentiometer

„„
This potentiometer is used when running speed setting is not frequently changed, or when twostep speed switching is
performed in combination with external speed setting.
Adjust the potentiometer using an insulated screwdriver. Clockwise rotation will increase the set speed. The speed is set
to 0 r/min at time of shipment.
When the motor is driven at the speed set by the internal potentiometer, turn on the INT.VR/EXT input.
When you want to use only the internal speed setting potentiometer to set the operation speed, you do not have to
connect the VRH, VRM and VRL.

Setting by external potentiometer

„„
This potentiometer is used when the speed is set away from the driver or when two-step speed switching is performed
in combination with the internal potentiometer.
Use the accessory PAVR2-20K as the external potentiometer.
Clockwise rotation will increase the set speed.

•• To set the running speed only by the external potentiometer, there is no problem if the INT.
VR/EXT input is not connected.
•• To perform operation by switching the motor running speed, use the INT.VR/EXT to switch the external potentiometer
and internal potentiometer.

Note To use a shielded cable for connection with the external potentiometer, connection should be made close to the I/O
signals cable connector. Connect the shielded wire to the pin No.3 GND.

19
Operation

Setting by external DC voltage

„„
External DC voltage is used when the speed is set by D/A output from an external control device such as a
programmable controller, or when the speed is switched over two levels during operation in combination with the
internal speed potentiometer.
For external DC voltage, use DC power supply (0 to 5 VDC, 1 mA or more) where the primary and secondary sides are
provided with reinforced insulation.

•• To set the running speed only by the external speed setter, there is no problem if the INT.VR/ EXT input is not
connected.
•• To perform operation by switching the motor running speed, use the INT.VR/EXT to switch the external DC voltage
and internal potentiometer.

Note •• The external DC power supply voltage must not exceed 5 VDC. Otherwise, the driver may be damaged.
•• When connecting the external DC power supply, sufficient care must be taken not to mistake power polarity.
Connection with incorrect polarity may damage the driver.
•• To use a shielded cable for connection with the external DC power supply, connection should be made close to the
I/O signals cable connector. Connect the shielded wire to the pin No.3 GND.

7.4 Setting the acceleration time and deceleration time

Set the acceleration time and deceleration time using the acceleration/deceleration time potentiometer (p.7). The
acceleration time and deceleration time are always identical.
Adjust the potentiometer using an insulated screwdriver. Turning the potentiometer clockwise increases the time. You
can set a desired time in a range of 0.5 to 10 seconds. The minimum time is set at time of shipment.
“Acceleration time” indicates the time required by the motor to reach the rated speed from a stopped condition.
“Deceleration time” indicates the time required by the motor to stop from the rated speed.
With the it indicates the time needed by the motor to reach 2500 r/min from a stopped condition or to stop from
2500 r/min (under no load). The actual acceleration/deceleration time is affected by the use condition, load inertia, load
torque and other conditions implemented by the user.

 Operation

7.5 Multi-motor control

If two or more motors are to be operated at the same speed, they can be controlled from the DC power supply or
external potentiometer.
Use external DC power supply
•• Use a DC power supply whose current capacity is at least the value calculated by the formula below:
Current capacity when N drivers are connected: I = 1 × N (mA)
Example: If two drivers are connected, the current capacity should be at least 2 mA.
•• All I/O signals other than the one used for speed setting should be connected to each driver.
•• If multiple motors are used with speed differences among them, make the following adjustments:
First motor: Connect a resistor of 1.5 kΩ, 1/4 W to the driver’s M terminal.
Second and subsequent motors: Connect a variable resistor (VRn) of 5 kΩ, 1/4 W to the applicable driver’s M terminal.
