1. Introduction
The Oriental Motor (OM) CFK Series is a family of 5-Phase Stepping Motor Units which are
available in single and double shaft versions. This manual describes the installation and use of
the motors in the CFK Series, and instructs you in the precautions you should take when using
these devices.
There are two frame sizes : CFK54 □□ and CFK56 □□

All CFK units consist of a motor and an electronic driver. The separately purchased power
supply, and the digital Controller, complete the system (Figure 1).
A comprehensive Troubleshooting Table on page 16 and 17 lists the symptoms, check points, and
action steps related to problems you may encounter using this device. If you require further
assistance, contact your local sales office.

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.

Figure 5 Flat Mounting
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).

Wiring of the CFK motors consists of interconnecting the Driver to the Power Supply via CN1,
to the Controller via CN2, and to the Motor via CN3.
The Wiring diagram for all connectors is shown in Figure 7. The power and signal connections
are detailed in Table 3 on page 8 and Table 4 on page 9.

・Keep signal lines as short as possible.
・Keep signal lines as far away as possible from power supply and motor lines.
・If noise generated on the motor lead wires causes interference with signal lines, shield the
motor
lead wires with conductive tape or wire mesh.
・Before turning on the power, always check the polarity of the power line which is arranged +24V,
+24V, GND, GND, +5V, GND from the left facing CN1.
・Make sure the housing and pin do not slip and get stuck when the connector is connected.
Wire Requirements for the CFKCFK

CFK
Note
・Use twisted pair hookup wire of minimum diameter 24 AWG for all signal control lines, and
20 AWG for all power lines.
・ Strip no more than 5.5 mm of insulation from the end of the lead wires to minimize the possibility
of short circuits.

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
input
A 4-bit signal input allows a
16-step change in motor
resolution.
Points inputted in bits are active at
L level.
Please refer to Table 5 on page 12

from each bit combination.

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.
