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.


For EMC directive
The EMC measurement is not performed on the individual motor or driver. The customer
is required to conduct the EMC measures on the final product incorporating the unit.

Safety precautions
The precautions described below are intended to prevent danger or injury to the user and
other personnel through safe, correct use of the product. Use the product only after
carefully reading and fully understanding these instructions.
Warning
Handling the product without observing the instructions that accompany a “Warning”
symbol may result in serious injury or death.
Caution
Handling the product without observing the instructions that accompany a “Caution”
symbol may result in injury or property damage.
Note
The items under this heading contain important handling instructions that the user should
observe to ensure safe use of the product.

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.
