2. Unit Components
CFK Units include a matched motor and driver, connectors and operating manual.
PRECAUTIONS
Motor/Driver Combinations
Do not use a motor with any driver other than that listed in Table 1. Other combinations may
cause damage to a component and improper or unsafe operation of the motor, both of which
will void your OM warranty.
Maintaining Motor Integrity
Never disassemble the motor or loosen its assembly screws. These activities will cause
significant performance drop and void your OM warranty.
Heat Generation
Do not touch the motor or driver during operation as both components generate high
temperatures.
Do not allow the motor case to exceed 100℃. Motor temperature can be lowered by reducing
operating RUN current, STOP current at motor standstill, speed, and duty cycle.
Before touching the motor or the driver, turn the power off allowing ample time for the unit to cool
down.

Installation areas for the motors and drivers should :
・Be free from water, dust, oil mist, salt or corrosive gas.
・Be free from excessive vibration or shock.
・Have good ventilation.
・Have ambient temperature for:
・Motor : between -10℃to +50℃, noncondensing.
・Driver : between 0℃to +40℃, noncondensing.
・Have at least 25 mm of open space between the driver and adjacent items.
Special considerations :
・Prevent contact between the driver and pieces of conductive material such as metal filings or
pins.
・Install motors on strong, heat-conducting metal plates such as steel or aluminum.
・If the temperature of the driver heat sink exceeds 85℃, force cool with a fan or attach
to a good heat conducting metal plate.
・Do not store or use in direct sunlight.
Electrical Noise
If the driver is located near significant sources of electrical noise such as high voltage lines, high
voltage machines or switched power units, insert noise filters in the source power line or connect
the driver to a separate circuit.

Mounting the Driver
Figure 4 shows the proper mounting of the driver for horizontal and vertical installation. When
mounted horizontally, the heat sink should face upward. A vertical mounting requires that the
terminal blocks face upward. For heat sink attachment, use M3-P 0.5 screws. The screw length
is 5 mm plus the thickness of the mounting plate.
Horizontal Installation
Figure 4 Driver Orientations
The driver can be attached to its mounting plate (or chassis) with screws through the driver
circuit board (Figure 5), or with screws through the heat sink (Figure 6).

Function
Movement occurs with a rising
pulse if pulse is input when either
side is at L level, the motor may
not run normally.
Turn motor output current off at
L level and the motor rotate freely.
H level is when nothing is
connected, and the motor will run
normally.
At L level, the automatic current
down function is cancelled.
H level results when nothing is
connected. There is an
approximate 50% automatic
current down on output current
when the motor is stopped at
H level (no connection).
A signal is output whenever the
motor excitation sequence returns
to step 0 in synchronization with
the input pulse signal. e.g.,
·Every 10 pulses
when 0.72°/ STEP
·Every 100 pulses
when 0.072°/STEP
GND terminal used for signal

Note 1 :This will vary according to the inertial load, torque load, self-starting frequency and the
like.
Please do not input a signal into the all windings off input before the motor is stopped.
Note 2 :Do not input a pulse signal directly after the all windings off input signal has been switched
to H level, as this will affect the motor's starting characteristics. Usually a delay of
100msec. is sufficient.
Note 3 :If a pulse is input when either side of the CW pulse input or CCW pulse input is at L level,
the motor may not run normally.

The stepping motor comes to rest after oscillating around its final rest position. Oscillation time
varies with the inertial load, friction load, self-starting frequency and motor type. Be sure that the
motor has come to a complete stop before inputting the All Windings Off Input signal. Activating
the All Windings Off Input prior to the completion of motor oscillation may make the motor lose its
resting position.
The All Windings Off Input signal affects the starting characteristics of the motor. After the All
Windings Off Input signal has been switched to HIGH, wait 100 msec. before inputting a pulse
signal.
All Windings Off Input

Resolution Selection
Motor resolution can be set to 16 values by varying the connections to the Resolution Selection
inputs D0 through D3. Therefore, the speed of the motor and the size of a step may be changed
by modifying the microstep resolution, without changing the input pulse frequency.
Do not change the resolution unless the pulse signal has stopped and the motor is stationary.

Adjusting the RUN Current
Your driver is delivered with the RUN current set to the rated operating current. To change this
value to reduce heat dissipation at high duty cycles, adjust the RUN potentiometer on the CFK
driver to the appropriate current value setting shown in Figure 12.
1. Turn on SW1 to disable the Automatic Current Down at standstill function.
2. Do not input any other signal (i.e., All Winding Off, Pulse, etc.).
3. Connect the motor to CN3 and insert an ammeter in the blue wire between terminal 1 and the
motor as shown in Figure 11.
4. Connect the power supplies, turn on the 5 VDC and 24 VDC, and adjust the RUN potentiometer
to the RUN current value of the appropriate graph in Figure 12.
DFC1507 DFC1514
Figure 12 RUN Potentiometer Settings
When the RUN potentiometer is turned clockwise to its internal stop, the output current of the

7. Troubleshooting
If the stepping motor is not functioning properly, perform the following checks and action steps.
If the motor continues to malfunction, please contact your local Oriental Motor Sales Office.
Table 6 Troubleshooting Chart
Action Steps
Check that the power supply is properly
wired and connected to a power source.
When the connector is connected, check
that the housing has not slipped and become
stuck.
The motor will not energize when the All
Windings Off input signal is at the L level.
When the All Windings Off input signal is at
L level the motor ceases to be energized.
The motor has holding torque.
Check that motor and driver are properly
wired.
Check if the potentiometers have been turned
too far down. Return them to their factory
settings and recheck the motor operation.
Check that the housing have not slipped and
become stuck.
Check the connection polarity, voltage and
waveform of pulse signals. Check if the pulse
inputs on other sides is at the H level.
Retighten the shaft coupling screws or check
that the load is disengaged. The load may be
too large or the motor and load may not be
properly centered.
Verify that the motor's step angle conforms with
the step angle required by the device.
Check that your pulse generator setting for the
input pulse number are appropriate for the
designated motor movement.
Symptom
Motor is not receiving
power. The shaft is
easily rotated by hand.
Motor rotates in the
opposite direction.
Motor is running, but is
not functioning
properly.

Action Steps
Disable the input.
The rate may be set too high.
Lower the rate and check the results.
The time may be set too short.
Lengthen the time and check the results.
Check the motor movement independently
without operating any other apparatus which
could be a potential source of noise.
Reduce the motor RUN current.
If the vibration is reduced after a change in
the pulse rate, the problem might be in the
resonance of the motor.
Change the pulse rate or step angle.
Shorten the motor operating time or
lengthen its rest time.
Reduce the duty cycle.
Lower the current setting at 50% of the RUN
Current.
Adjust to the optimal value.
Current cannot be lowered when this
potentiometer is in MAX position.
Turn this potentiometer to the left after
referring to the appropriate graph in Figure 13
on page 15.
Be sure to return the pulse signal to the H level.
When the pulse signal is maintained at the
L level, the current cannot be lowered.
