Introduction
Before using the motor unit
Only qualified personnel should work with the product.
Use the product correctly after thoroughly reading the section “Safety precautions.”
The product described in this manual has been designed and manufactured for use in
general industrial machinery, and must not be used for any other purpose. For the driver’s
power supply, use a DC power supply with reinforced insulation on its primary and
secondary sides. Oriental Motor Co., Ltd. is not responsible for any damage caused
through failure to observe this warning.
Overview of the product
The CFKII series is a unit comprising of an open-case, high-performance micro-step driver
and high-torque, low-vibration design 5-phase stepping motor. The use of micro-stepping,
which gives the basic step angle of the motor greater precision, electrically provides lower
vibration and lower noise with accurate angle operation without the need for a speed-
reduction mechanism.
Conformance with EC directives
Take the following measures to ensure conformance with the EC’s low voltage directive
and EMC directive.


For low voltage directive
This product is not subject to the EC’s low voltage directive because its input power
supply voltage is 24 VDC. However, the user is advised to perform the following actions
when conducting product installation and connection.
• This product is designed for use within machinery, so it should be installed within an
enclosure.
• For the driver’s power supply, use a DC power supply with reinforced insulation on its
primary and secondary sides.


Warning
General
• Do not use the product in explosive or corrosive environments, in the presence of
flammable gases, locations subjected to splashing water, or near combustibles. Doing
so may result in fire or injury.
• Assign qualified personnel the task of installing, wiring, operating/controlling, inspecting
and troubleshooting the product. Failure to do so may result in fire or injury.
Installation
• Install the motor and driver in their enclosures in order to prevent injury.
Connection
• Keep the driver’s input-power voltage within the specified range to avoid fire.
• For the driver’s power supply, use a DC power supply with reinforced insulation on its
primary and secondary sides. Failure to do so may result in electric shock.
• Connect the cables securely according to the wiring diagram in order to prevent fire.
• Do not forcibly bend, pull or pinch the power cable or motor lead wire. Doing so may
result in fire.
Operation
• Turn off the driver power in the event of a power failure, or the motor may suddenly start
when the power is restored and may cause injury or damage to equipment.
• If this product is used in an elevator application, be sure to provide a measure for the
position retention of moving parts. The motor loses its holding torque when the power is
turned off. Failure to provide such a measure may cause the moving parts to fall off,
resulting in injury or damage to the equipment.
• Do not turn the A.W.OFF (All Windings Off) input to “ON” while the motor is operating.
The motor will stop and lose its holding ability, which may result in injury or damage to
the equipment.
Repair, disassembly and modification
• Do not disassemble or modify the motor or driver. This may cause injury. Refer all such
internal inspections and repairs to the branch or sales office from which you purchased
the product.

5
Caution
General
• Do not use the motor and driver beyond their specifications, or injury or damage to
equipment may result.
• Do not touch the motor or driver’s heat sink during operation or immediately after
stopping. The surfaces are hot and may cause a burn.
Transportation
• Do not hold the motor output shaft or motor lead wire. This may cause injury.
Installation
• Keep the area around the motor and driver free of combustible materials in order to
prevent fire or a burn.
• To prevent the risk of damage to equipment, leave nothing around the motor and driver
that would obstruct ventilation.
• Provide a cover over the rotating parts (output shaft) of the motor to prevent injury.
Operation
• Use a motor and driver only in the specified combination. An incorrect combination may
cause a fire.
• To avoid injury, remain alert during operation so that the motor can be stopped
immediately in an emergency.
• Before supplying power to the driver, turn all input signals to the driver to “OFF.”
Otherwise, the motor may start suddenly and cause injury or damage to equipment.
• Before moving the motor directly with the hands (as in the case of manual positioning),
confirm that the driver A.W.OFF (All Windings Off) input is “ON” to prevent injury.
• When an abnormality is noted, stop the operation immediately, or fire or injury may
occur.
Disposal
• When disposing of the motor or driver, treat them as industrial waste.

Names and functions of parts
This section covers the names and functions of parts in the driver and motor.
Note
• Even when the motor is stopped, the current remains on and the motor continues to
generate heat.
• While the motor is in the stopped state, the current is automatically reduced to a value
preset by the motor-stop current-adjustment control (STOP) to limit the generation of
heat. The motor’s holding torque is also reduced in proportion to the stopped-state
current. Adjust the motor-stop current-adjustment control (STOP) setting to ensure the
necessary load-holding torque.

Align the centers of the motor’s output shaft and load shaft in a straight line.


Using a belt drive
Align the motor’s output shaft and load shaft in parallel with each other, and position both
pulleys so that the line connecting their centers is at a right angle to the shafts.


Using a gear drive
Align the motor’s output shaft and gear shaft in parallel with each other, and let the gears
mesh at the center of the tooth widths.
Note
• When coupling the load to the motor, pay attention to the centering of the shafts, belt
tension, parallelism of the pulleys, and so on.
Securely tighten the coupling and pulley set screws.
• Be careful not to damage the output shaft or bearings when installing a coupling or
pulley to the motor’s output shaft.
• Do not modify or machine the motor’s output shaft.
Doing so may damage the bearings and destroy the motor.

14
Overhung load and thrust load
The overhung load on the motor’s output shaft must be kept under the permissible values
listed below.
The thrust load must not exceed the motor’s mass.

Installing the driver


Installation method
Install the driver on a flat metal plate having superior capacity to withstand vibration as
well as a high heat-conductance effect. Always install the driver using the driver’s
installation holes and install and fasten it either vertically or horizontally with the two screws
(M3; not supplied with unit) so that there is no gap between the driver and the metal plate.
Any other installation method will reduce the heat-radiating effect for the driver.
There must be a clearance of at least 0.98 in. (25 mm) and 1.97 in. (50 mm) in the
horizontal and vertical directions, between the driver and enclosure or other equipment.
When two or more drivers are to be installed side by side, provide 0.79 in. (20 mm)
clearances in the horizontal.
Note
• Do not install any equipment that generates a large amount of heat near the driver.
• Check ventilation if the ambient temperature of the driver exceeds 104°F (40°C).

Connection
This section covers the methods of connecting the driver, motor, power and controller, as
well as the connection examples and I/O interface.
Terminal blocks
Screw terminals are used.
Remove the insulation from the core, then insert the core into the terminal and tighten with
terminal screws.
Strip 0.24 to 0.31 in. (6 to 8 mm) of insulation.
Tighten the terminal screw at the specified tightening torque.
Connecting the motor
Connect the motor leads into the driver’s motor terminal block (TB2).
The CFK513 model has a connector with motor leads. Use the supplied motor cable with
connector.
Note
If the noise generated from the motor leads becomes a problem, shield the motor leads
with electrically conductive tape, wire mesh or the like.
Connecting to the power supply
The input power-supply voltage is 24 VDC ±10%. Use a power supply capable of
supplying the power/current capacity as shown below.
Driver model DFC5103T, DFC5107T
1 A min. DFC5114T 2 A min. DFC5128T 4 A min.
Connecting the power-supply wires into the driver’s power-supply terminal blocks (TB1).
Note
• For the power-supply cable, use a cable with a diameter equivalent to AWG20 (0.5 mm2)
for the standard type (DFC5103T, DFC5107T, DFC5114T), and AWG20 to 18 (0.5 to
0.75 mm2) for the high-speed type (DFC5128T). Be sure to connect the power supply
using the correct polarity. If the power supply’s polarity is reversed, the driver may be
damaged.
• Do not route the power-supply cables in the same conduits as other power-supply lines
and motor leads.
• Always wait at least 5 sec. after switching off the power before switching it back on
again or connecting/disconnecting the motor-lead connector.

17
Connecting the I/O signals
Connecting the I/O wires into the driver’s I/O signal terminal blocks (TB3).
Note
• For the I/O signal cable, use twisted pair with a diameter equivalent to at least AWG24 to
22 (0.2to 0.34 mm2). To suppress the effect of noise, make the cable as short as
possible [6.6 ft. (2 m) max.].
• Separate I/O signal cables at least 12 in. (300 mm) from electromagnetic relays and
other than inductance loads. Additionally, route I/O signal cables perpendicular to power-
supply cables and motor leads, rather than in a parallel fashion.
Terminal blocks pin assignments
∗Depends on the setting of the pulse-input selector switch.
• When this switch is set to 1-pulse input mode, the inputs are the pulse input and the
rotation-direction input.
• When this switch is set to 2-pulse input mode, the inputs are CW and CCW.

Note
• Make the input-signal voltage 5 VDC minimum and 24 VDC maximum.
When the input-signal voltage is 5 VDC, external resistors R1 and R2 in the diagram are
not necessary. If the input-signal voltage is greater than 5 VDC, connect external
resistors R1 and R2, as shown in the diagram, to restrict the input current as follows:
PLS, DIR: 20 mA max.
A.W.OFF, C/S: 15 mA max.
• Use an output-signal voltage of 5 VDC minimum and 24 VDC maximum, and use
output-signal current of 10 mA max.
If the output-signal current is greater than 10 mA, connect external resistor R3, as shown
in the diagram, to restrict the current to no more than 10 mA.
Connection examples
Examples of connections with the motor, power supply and controller are shown below.

Input signals
The signal states indicate the state of the internal photocoupler (ON: power conducted;
OFF: power not conducted).


PLS input and DIR input
This driver can select either 1-pulse input mode or 2-pulse input mode as the pulse-input
mode to match the controller used. For details on how to set the pulse-input mode, see
page 29, “Pulse input modes.”
1-pulse input mode (factory setting)
The controller pulses are connected to the PLS+ input (pin No.1) or the PLS - input (pin
No.2), and the rotation direction is connected to the DIR+ input (pin No.3) or DIR
- input
(pin No.4).
1.When the DIR input is “ON,” a fall of the “PLS input” from “ON” to “OFF” will rotate the
motor one step in the CW direction.
2.When the DIR input is “OFF,” a fall of the “PLS input” from “ON” to “OFF” will rotate the
motor one step in the CCW direction.

Note
• Do not allow the driver temperature to exceed 158°F (70°C), which is the heat-radiating
plate’s saturation temperature during operation.
• The minimum value for the interval time when switching the rotational direction depends
on the motor’s size, running speed and load moment of inertia.
