1 Introduction

Before using the product

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 CRK series is a unit product comprised of an open-case microstep driver equipped with smooth drive function and a five-phase stepping motor or various geared motors designed for high torque and low vibration. The smooth drive function allows microstep drive to be performed automatically within the driver without having to change the pulse setting, thereby enabling low vibration, low noise operation.

? 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.

? EMC Directive (89/336/EEC, 92/31/EEC)

This product bears the CE mark under the conditions specified in "Example of motor and driver installation and wiring" on p.28. Be sure to conduct EMC measures with the product assembled in your equipment by referring to 5.6 "Installing and wiring in compliance with EMC Directive" on p.26.

2 Safety precautions

2 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.

Handling the product without observing the instructions that

Warning accompany a "Warning" symbol may result in serious injury or

death.

Handling the product without observing the instructions that

Caution 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.

? 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 supply is turned off. Failure to provide such a measure may cause the moving parts to fall, resulting in injury or damage to the equipment.

Installation

? Install the motor and driver in their enclosures in order to prevent injury.

Connection

? Keep the driver's power supply input 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 supply cable or motor cable. Doing

so may result in fire.

2 Safety precautions

Operation

? Turn off the driver power supply 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.

? Do not turn the A.W.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.

Caution

General

? Do not use the motor and driver beyond their specifications, or injury or damage to equipment may result.

? Keep your fingers and objects out of the openings in the motor and driver, or fire or injury.

? Do not touch the motor or driver during operation or immediately after stopping. The surfaces are hot and may cause a skin burn(s).

? If the power supply cable or motor cable connected the driver are forcibly bent or pulled, the driver will receive stress and may suffer damage.

Transportation

? Do not hold the motor output shaft or motor cable. This may cause injury.

Installation

? Keep the area around the motor and driver free of combustible materials in order to prevent fire or a skin burn(s).

? 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.

? Provide an emergency stop device or emergency stop circuit external to the equipment so that the entire equipment will operate safely in the event of a system failure or malfunction. Failure to do so may result in injury.

? 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.
