UNPLUGGING

Warning Failing to follow the precaution items given below may

lead to severeinjury or death.

• Do not use this unit with voltages other than the speci ed supply voltage as

this may result in  re or electric shock.

• Do not perform installation work with wet hands as this may result in electric

shock.

• Do not disassemble or modify the unit as this may result in injury or damage

the internal circuits.

Caution Failing to follow the precaution items given below may

lead to injury or damage to surrounding objects.

• Be sure to check the machine and device conditions to ensure work safety

before working on the machine.

•

Be sure to cut o the power supply and other sources of drive power before

installing the working on the machine. Failure to do so may result in  re or

accidents.

1. Notes to Users

1-1. General Precautions

When using Magnescale Co., Ltd. products, observe the following general precautions

along with those given speci cally in this manual to ensure proper use of the products.

• Before and during operations, be sure to check that our products function properly.

• Provide adequate safety measures to prevent damages in case our products should

develop malfunctions.

• Use outside indicated speci cations or purposes and modi cation of our products will

void any warranty of the functions and performance as speci ed of our products.

• When using our products in combination with other equipment, the functions and

performances as noted in this manual may not be attained, depending on operating

and environmental conditions.

1-2. Precautions

When installing the MJ632, observe the following precautions to prevent noise interference

from other equipment.

• Use noise-preventive mechanisms for the relays, solenoids and motors connected to

the MJ632.

• Take preventive steps when noise from other equipment may disturb the power supply

line to the units.

• Shield the output cable correctly according to the instruction manual.

Be sure to ground the MJ632 with an earth wire or by mounting it on the machine with

screws.

1-3. Installation

• Use the MJ632 in the temperature range of 0 to 45 °C. Do not expose it to sunlight or

sources of heat. A well-ventilated place is preferable.

• Separately route the head cable and output cable from the power line.

• When installing the Interpolator in a place where it may be exposed to water splashes,

protect it from water by providing a cover or other protection.

2. Introduction

 is product is an interpolator specially for the PL101 head unit.

Combining with the PL101 head unit enables output of AB quadrature signals at a

resolution of 0.2 to 10 μm.

C : Honda Tsushin 20-pin

B : Unterminated end

2-3. Main Features

• Operation uses a single 4.75 to 5.25 V DC power supply.

• Reference point signals are output in synchronization with the AB quadrature signals.

•  e output signals are AB quadrature signals, reference point signals, and alarm

signals, and the signals are output by a voltage-di erential line driver compliant with

EIA-422.

•  e PL101 head unit travel is detected in 50 ns increments and is output at a phase

di erence time proportional to the amount traveled.  e phase di erence time changes

in integral multiples of 50 ns

• When alarm signals are detected, the alarm signals become active, and AB quadrature

signals change to high impedance.

3-2. AB Quadrature Signal Minimum Phase Di erence Time

and Maximum Response Speed

 e AB quadrature signal minimum phase di erence time changes based on the travel

speed of the head unit. When a minimum phase di erence time that is less than the AB

quadrature signal minimum phase di erence time of your model is reached, a speed

alarm is output. (See “2-2. Model Name”.)  e speed just before the speed alarm is output

is the maximum response speed.

resolutions of 0.2 μm and 0.5 μm are not available.

3-3. Movement Direction and Output Phase Relationship

 e phase relationship between AB quadrature signals is shown in the table below.  e

phase relationship varies depending on the travel direction and polarity.

 e polarity can be con rmed based on the model name of your product. (See “2-2. Model

Name”.)

3-4. Reference Point

 e MJ632 converts the reference point signals detected by the head unit to a reference

point signals in synchronization with the AB quadrature signals and outputs them.

In the reference point output signal width, the synchronized reference point signals are

output while both the signal A and signal B are at the Hi level.
