Before using this product

This section covers an overview of the

CSK

Series and explains how to comply with the EC Directives, as

well as items included in the package.

Introduction

The

CSK

Series high-torque 2-phase stepping motor is a unit product consisting of a driver of the open-

chassis type, photocoupler I/ O specification and a 2-phase stepping motor designed for high-torque

operation.

We offer the standard type and high torque type with a base motor step angle of 1.8°, and the high-

resolution type with a 0.9° step angle.

A geared type is also available.

Main features

●

Compact driver

The

CSK

Series adopts a compact driver using DC power supply input, making it ideal for use as an

internal component in general industrial equipment.

●

Two step angle settings

Either full step or half step can be selected as the step angle setting for the motor. See page 30.

●

Adjustable motor-driving currents

The operating current and standstill current of the motor can be adjusted individually. See page 32.

●

High-torque geared motor

The geared type adopts a directly coupled gearhead designed to withstand high torque.

■

System configuration

Operating the

CSK

Series requires a controller equipped with a pulse output function.

to take full responsibility for the following measures:

The installation conditions that must be satisfied to meet the above directives are as follows:

1. Install the motor and driver inside an enclosure.

2. Use an EMC-compliant DC power source with reinforced insulation on both the primary and secondary

sides.

3. Provide protective grounding for the DC power source.

4. Use braided-screen cable for I/O cables.

5. Use a mains filter.

■

Low-Voltage Directive (73 / 23/ EEC)

The

Series motors and drivers are not subject to the Low-Voltage Directive, since their input power

source voltage is 36 VDC or below. However, the product must satisfy the following conditions with

regard to installation and connection:

●

Use the product in a protected environment within an enclosure.

●

As for the driver’s and digital I/O signal’s power source, use a DC power source with reinforced

insulation on both the primary and secondary sides.

Installation

Connection

This product is designed for incorporation into industrial equipment. Touching the product during

operation may result in bodily injury or property damage, since the output shaft is rotating and the surface

remains very hot.

To prevent bodily injury or damage to the product, be sure the product is handled and operated only by

qualified personnel familiar with operations involving electronic equipment.

The precautions provided in this section are intended to ensure safe and correct use of the product,

thereby preventing damage or injury to the user or other personnel. Fully understand the meaning of

each item before using the product.

●

Install the motor and driver in an enclosure so

that the operator cannot touch them. Direct

contact may result in injury.

●

Always use the driver with a power source of the

rated voltage. Failure to do so may result in fire

or electric shock.

●

For the driver, use a DC power source with

reinforced insulation provided on the primary and

secondary sides. Failure to do so may result in

electric shock.

●

The digital I/ O part does not have reinforced

insulation. For the digital I/ O, use a DC power

source with reinforced insulation provided on the

primary and secondary sides. Failure to do so

may result in electric shock.

●

Connect the product correctly and securely

according to the wiring diagram. Failure to do so

may result in fire.

●

Do not forcibly bend, pull or pinch the cable.

Doing so may result in fire.

●

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.

●

Provide a measure to retain the position of the

movable part of the equipment when the product

is used in a vertical application. The motor loses

its holding capability when the power is cut off.

Without an appropriate measure the movable

part will descend, resulting in injury or equipment

damage.

Warning

Handling the product without observing

the instructions that accompany a

“ Warning” symbol may result in death

or serious bodily injury.

Caution

Handling the product without observing

the instructions that accompany a

“ Caution ” symbol may result in bodily

injury or property damage.

These notes appear throughout the

manual and describe items that must

be observed by the user in certain

situations to ensure correct use of the

product.

NOTE

General

Warning

●

Do not use the product in an atmosphere

containing explosive, flammable or corrosive

gases, in a place exposed to water, or near

flammable objects. Doing so may result in fire or

injury.
