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.

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.

3. Installation

Mounting the Motor

There are two motor frame sizes as seen in Figure 2 : CFK54 □A(B) and CFK56 □A(B).

Panel cutout requirements are shown in Figure 3 and corresponding dimensions and angles are

detailed in Table 2. Motors are supplied with single or double shafts.

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

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.

5 VDC ±5%, 0.1 A min.

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

resolution.

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.
