Precautions for use
•When conducting the insulation resistance measurement and
the dielectric strength test, be sure to separate the connection
between the motor and the driver.
Conducting the insulation resistance test or dielectric strength test with the
motor and driver connected may result in damage to the product.
•Regeneration
When a large load inertia is operated at a high speed, the power supply
voltage may increase by the regenerated energy generated, causing an
alarm of overvoltage to generate. This may result in damage to the driver, so
reconsider the operating condition so as not to generate the regenerative
voltage.

Explanation of I/O signals
zInput signals
The signal input state represents "ON: Carrying current" or "OFF: Not carrying
current" state of the internal photocoupler.
The interval for switching the motor direction represents the response time of
the circuit. Set this interval to an appropriate time after which the motor will
respond.
•PLS (CW) input, DIR (CCW) input
Set a desired pulse input mode of the driver according to the pulse output
mode of the controller used with the driver.
Maximum input pulse frequency (duty cycle is 50%)
yWhen the controller is of line driver type: 1 MHz
yWhen the controller is of open-collector type: 250 kHz
1-pulse input mode
When the PLS input is turned from OFF to ON while the DIR input is ON, the
motor will rotate by one step in CW direction.
When the PLS input is turned from OFF to ON while the DIR input is OFF, the
motor will rotate by one step in CCW direction.
2-pulse input mode
When the CW input is turned from OFF to ON, the motor will rotate by one
step in CW direction.
When the CCW input is turned from OFF to ON, the motor will rotate by one
step in CCW direction.
yWhen the motor is at standstill, be sure to keep the photocoupler in
OFF state.
yDo not input the CW pulse and CCW pulse simultaneously. If the
other pulse is input while one of the pulse is ON, the motor cannot
operate normally.
Pulse signal
Pulses with sharp rising and falling edges should be input as shown in the
gure below. The gure shows the voltage levels of pulse signals.
90%

0.4 µs or more 0.4 µs or more
1 µs or more
2 µs or less 2 µs or less
ON

•AWO (all windings o) input
When the AWO input is turned ON, the motor current will be cut o and the
motor will lose its holding torque. The motor output shaft can be turned
manually.
When the AWO input is turned OFF, current will be supplied and the holding
torque will be restored.
•CS (step angle switching) input
When the CS input is turned ON, the motor rotates at a basic step angle.
When the CS input is turned OFF, the motor rotates at the step angle set by
the driver switch.
yDo not change the CS input while operating. The motor may lose its
synchronism, causing position deviation or standstill of the motor.
yWhen changing the step angle using the CS input, do so while the
TIM output is ON.
zOutput signals
The driver outputs signals are photocoupler/open-collector output. The
signal output state represents "ON: Carrying current" or "OFF: Not carrying
current" state of the internal photocoupler.
•ALM (alarm) output
The ALM output is normally closed. When an alarm generates, the ALM
output will turn OFF and the motor current will be cut o.
At the same time, the PWR/ALM LED of the driver will blink in red.
•TIM (timing) output
Every time the motor output shaft rotates by 7.2° (3.6° for high-resolution
type), the motor excitation state becomes the initial setting state (step 0), and
the TIM output turns ON. If an AND circuit is congured with signals of the
home sensor and TIM output when the home position in the equipment is
detected, the tolerance for the motor stop positions in a detection range of
the home sensor can be reduced and the further accurate home position can
be detected.

Noise measures
The electrical noise is of two types: 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 aected by the noise.
For the noise that is emitted from the driver, take measures to suppress it.
zMeasures against electrical noise
There are the following three methods mainly to take measures against the
electrical noise.
•Noise suppression
yWhen relays or electromagnetic switches are used together with the
system, use noise lters and CR circuits to suppress surges generated by
them.
yCover the driver by a metal plate such as aluminum. This is eective in
shielding the electrical noise emitted from the driver.
•Prevention of noise propagation
yPlace the power lines, such as the motor and power supply cables, keeping
a distance of 100 mm (3.94 in.) or more from the signal lines, and also do
not bundle them or wire them in parallel. If the power cables and signal
cables have to cross, cross them at a right angle.
yUse shielded twisted pair cables of AWG22 (0.3 mm2) for power lines and
AWG24 to 22 (0.2 to 0.3 mm2) for signal lines.
yKeep cables as short as possible without coiling and bundling extra lengths.
yTo ground a shielded cable, use a metal cable clamp that will maintain
contact with the entire circumference of the cable. Ground the cable clamp
near the product.
Cable clamp
Shielded cable
yWhen grounding PE terminals of multiple drivers to a grounding point,
it becomes more eective to block the electrical noise since impedance
on the grounding point is decreased. However, ground them so that a
potential dierence does not occur among the grounding points. An
accessory connection cable (for signal) that includes a ground wire is
provided. Refer to p.12 for details.
•Suppression of eect by noise propagation
yLoop 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. To increase the eect of noise attenuation by the ferrite
core, loop the cable a lot.
yUse the line driver type, which is less likely to be aected by electrical noise,
for the output circuit of pulse signals. If the pulse signal of the controller is
of the open collector type, use an accessory pulse signal converter for noise
immunity. Refer to p.12 for details.

zNoise suppression parts (accessories)
Refer to p.12 for accessories.
•Connection cable (for signal)
This cable is a shielded twisted pair cable for good noise immunity to connect
the driver and controller. The ground wires useful to grounding are provided
at both ends of the cable. The EMC measures are conducted using the
Oriental Motor connection cable.
•Pulse signal converter for noise immunity
This is a noise lter for pulse signal lines. It eliminates the noise of the pulse
signal, and converts the pulse signal to the line driver type.
•Surge suppressor
This product is eective to suppress the surge which occurs in a relay contact
part. Connect it when using a relay or electromagnetic switch. CR circuit for
surge suppression and CR circuit module are provided.
Conformity to the EMC Directive
Eective 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.2 for the applicable standards.
Oriental Motor conducts EMC measurements on its motors and drivers in
accordance with the following "Example of motor and driver installation and
wiring."
The user is responsible for ensuring the machine's compliance with the EMC
Directive, based on the installation and wiring explained below.
•Power supply
The CVK Series is a product of DC power input. Use a DC power supply
(switched-mode power supply etc.) that conforms to the EMC Directive.
•Connecting the signal cable
Refer to "Prevention of noise propagation" on p.9.
•How to ground
yThe cable used to ground the motor and driver must be as thick and short
as possible so that no potential dierence is generated.
yChoose a large, thick and uniformly conductive surface for the grounding
point.
yInstall the motor to the grounded metal plate.

yStep angles are theoretical values.
yDo not change the CS input or switches while operating. Doing so
may cause loss of synchronism of the motor, resulting in the motor
standstill.
yFor the high-resolution type, in comparison with the standard type
the resolution is twice and the step angle is one-half.
Example: When the R2/R1 switch is set to the ON side (R1) and the
STEP switch is set to "0"
Resolution of the high-resolution type: 500 × 2 = 1000
Step angle of the high-resolution type: 0.72°/2 = 0.36°
Pulse input mode
Set a desired pulse input mode of the driver according to the pulse output
mode of the controller used with the driver. Set a desired mode using the
1P/2P switch. The factory setting of the pulse input mode depends on the
destination country.

Smooth drive function
The smooth drive is a function to achieve lower vibration and noise at low
speeds operation without changing the step angle setting.
This function divides the step angle automatically in response to the pulse
signals. It is no need to change the setting of the pulse signals (speed, number
of pulses) on the controller side.
Set the smooth drive function with the OFF/SD switch.
Factory setting ON side (SD) [smooth drive function is enabled.]
Operating current
If the operating current rate is set with the RUN switch, the motor current for
when inputting pulses (operating current) can be changed.
If the load is small and there is an ample allowance for torque, motor
temperature rise can be suppressed by setting a lower operating current rate.
The operating current is a value in which the operating current rate is
multiplied by the rated current (100%).
Operating current = Motor rated current × Operating current rate
Factory setting F (operating current rate 100%)
RUN switch Operating

4 45% C 85%
5 50% D 90%
6 55% E 95%
7 60% F 100%
Standstill current
When the motor stops, the current cutback function will be actuated to lower
the motor current to the standstill current.
The driver standstill current rate can be switched between 25% and 50%
using the STOP switch. When setting the switch to the OFF side, the standstill
current rate will be set to 25%. When setting the switch to the ON side, the
standstill current rate will be set to 50%.
The standstill current is a value in which the standstill current rate is
multiplied by the operating current.
Standstill current = Operating current set with the RUN switch × Standstill
current rate

Command lter
The motor response corresponding to input pulses can be adjusted with the
OFF/FIL switch. When the switch is set to the ON side, starting/stopping of the
motor becomes smooth. Note, however, that synchronization performance in
response to the commands is decreased.

Inspection
It is recommended that periodic inspections are conducted for the items
listed below after each operation of the motor. If an abnormal condition is
noted, discontinue any use and contact your nearest Oriental Motor sales
oce.
During inspection
yAre any of the mounting screws or connection parts of the driver loose?
yIs there attachment of dust, etc., on the driver?
yAre there any strange smells or appearances within the driver?
The driver uses semiconductor elements, so be extremely careful
when handling them. Static electricity may damage the driver.
Alarms
When the driver's protective function triggers and an alarm generates, the
ALM output is turned OFF and the motor current is cut o.
At the same time, the PWR/ALM LED will blink in red. The cause of the alarm
can be checked by counting the number of times the PWR/ALM LED blinks.
