A- 1
1. To prevent electric shock, note the following
WARNING
Before wiring or inspection, turn off the power and wait for 15 minutes or more until the charge lamp turns
off. Then, confirm that the voltage between P( ) and N( ) is safe with a voltage tester and others.
Otherwise, an electric shock may occur. In addition, always confirm from the front of the servo amplifier,
whether the charge lamp is off or not.
Connect the servo amplifier and linear servo motor to ground.
Any person who is involved in wiring and inspection should be fully competent to do the work.
Do not attempt to wire the servo amplifier and linear servo motor until they have been installed. Otherwise,
you may get an electric shock.
Operate the switches with dry hand to prevent an electric shock.
The cables should not be damaged, stressed, loaded, or pinched. Otherwise, you may get an electric shock.
During power-on or operation, do not open the front cover of the servo amplifier. You may get an electric
shock.
Do not operate the servo amplifier with the front cover removed. High-voltage terminals and charging area
are exposed and you may get an electric shock.
Except for wiring or periodic inspection, do not remove the front cover even of the servo amplifier if the
power is off. The servo amplifier is charged and you may get an electric shock.
2. To prevent fire, note the following
CAUTION
Install the servo amplifier, servo motor and regenerative resistor on incombustible material. Installing them
directly or close to combustibles will lead to a fire.
Always connect a magnetic contactor (MC) between the main circuit power supply and L1, L2, and L3 of
the servo amplifier, and configure the wiring to be able to shut down the power supply on the side of the
servo amplifier’s power supply. If a magnetic contactor (MC) is not connected, continuous flow of a large
current may cause a fire when the servo amplifier malfunctions.
When a regenerative resistor is used, use an alarm signal to switch main power off. Otherwise, a
regenerative transistor fault or the like may overheat the regenerative resistor, causing a fire.
3. To prevent injury, note the follow
WARNING
The linear servo motor uses a strong magnet on the secondary side. Therefore, not only the linear servo
motor installation operators but also the machine operators must use abundance of caution. For example,
one who uses a medical device like a pacemaker must keep away from the machine.
The permanent magnet on the secondary side makes the magnetic bodies generate suction. Use caution
with accidents so as not to get your hand stuck.
The performance is not guaranteed if the specified servo amplifier and linear servo motor are not
combined. If used with unspecified combination, the servo amplifier or linear servo motor may be
damaged. Depending on the case, it can be out of control and operate unexpectedly, resulting in
extremely dangerous condition.
A- 2
WARNING
Under the packaged condition (cardboard) delivered from our company, the magnet on the secondary
side does not have a serious effect on the outside. Before mounting to the machine, however, magnetic
bodies (including tools) must be kept away from the secondary side (magnetic). The secondary side
(magnetic) can have as double suction power as mounted normally, which may cause a serious injury. To
avoid this, pay full attention to the ambience of workplace.
CAUTION
Only the voltage specified in the Instruction Manual should be applied to each terminal, Otherwise, a
burst, damage, etc. may occur.
Connect the terminals correctly to prevent a burst, damage, etc.
Ensure that polarity ( ,
) is correct. Otherwise, a burst, damage, etc. may occur.
Take safety measures, e.g. provide covers, to prevent accidental contact of hands and parts (cables, etc.)
with the servo amplifier heat sink, regenerative resistor, linear servo motor, etc. since they may be hot
while power is on or for some time after power-off. Their temperatures may be high and you may get burnt
or a parts may damaged.
The linear servo motor installation operators and machine operators must not work wearing electronic
devices (watch, calculator, personal computer, etc.) and magnetic recording media (IC card, magnetic
card, floppy disc, etc.) and must not bring them around a magnetic. The magnetic influence may cause
the operation failure or malfunction.
When the protective function is operated, turn off the power immediately and eliminate its cause, and then
turn it on again. If the linear servo motor is continued operating without eliminating the cause, it may run
unexpectedly and results in a damage and injury.
Securely attach the linear servo motor to the machine. If attach insecurely, it may come off during
operation.
4. Additional instructions
The following instructions should also be fully noted. Incorrect handling may cause a fault, injury, electric shock,
etc.
(1) Transportation and installation
CAUTION
Transport the products correctly according to their weights.
Stacking in excess of the specified number of products is not allowed.
Do not carry the linear servo motor by the cables, shaft or encoder.
Do not hold the front cover to transport the servo amplifier. The servo amplifier may drop.
Install the servo amplifier in a load-bearing place in accordance with the Instruction Manual.
Do not climb or stand on servo equipment. Do not put heavy objects on equipment.
The servo amplifier and linear servo motor must be installed in the specified direction.
Leave specified clearances between the servo amplifier and control enclosure walls or other equipment.
Do not install or operate the servo amplifier and linear servo motor which has been damaged or has any
parts missing.
A- 3
CAUTION
Provide adequate protection to prevent screws and other conductive matter, oil and other combustible
matter from entering the servo amplifier and linear servo motor.
Do not drop or strike servo amplifier or linear servo motor. Isolate from all impact loads.
The protection method of the linear servo motor is IP00. Take necessary measures against dust, oil, etc.
(Refer to section 2.1.2 Installation direction.)
When mounting the secondary side (magnet), use nonmagnetic tools.
Securely attach the linear servo motor to the machine. If attach insecurely, the linear servo motor may
come off during operation.
Do not modify the linear servo motor.
Take safety measures, e.g. provide covers, to prevent accidental access to the linear servo motor during
operation.
The dynamic brake can be applied to the linear servo motor, but the coasting distance becomes longer
when the moving body is heavy or when the speed is high. It may result in crashing into the stroke edge,
which is highly dangerous. Install the anti-crash mechanism such as an air brake or an electric/mechanical
stopper such as a shock absorber to reduce the shock of movable parts. (No linear servo motor with an
electromagnetic brake is available.)
The magnetic suction power acting between the primary side (coil) and the secondary (magnet) is always
acting even when the motor power is not turned on. Because of this, the machine must be designed to be
rigid enough to resist the magnetic suction power and maintain the accuracy.
The running load by friction increases in proportion to the increase of the magnetic suction power, so the
design must be made to decrease as much friction as possible, for example, by mounting guides with high
accuracy.
Do not use for vertical motion applications since magnetic poles cannot be detected with a vertical
application.
Install the linear servo motor the way in which the thrust acts on the gravity center of the movable part.
When the thrust does not act on the gravity center of the movable part, the moment is generated.
Magnetic chips such as iron fragments can be attached to the permanent magnet on the secondary side,
which may cause a malfunction. In the environment like this, take measures against the attachment and
entry of magnetic chips.
When the linear servo motor is operated over a long term under the condition where water for cutting or
lubrication oil is splashed or where oil mist or dew condensation occurs due to supercooling or high
humidity, insulation deterioration or other failures may be caused. Prevent the linear servo motor from oil
and dust with a cover and take measures against dew condensation.
More careful measures against oil and dust must be taken for the linear encoder than the linear servo
motor. For details, please contact the linear encoder manufacturer individually.
The moving direction of the linear servo motor and linear encoder must be matched. Otherwise, the motor
may run unexpectedly.
When two or more secondary side (magnet) is mounted, set the mounting screw accumulative pitch
tolerance within 0.2mm. Clearance may be left between the secondary sides (magnets) depending on
the mounting method and the numbers.
Do not hit the primary side (coil) on the stopper. The primary side may be damaged. Design the machine
so that the stopper is hit on the top table attached to the primary side (coil).
Tap holes on the linear servo motor are for machine installation. Do not use for other purposes.
Do not touch the linear servo motor with wet hands.
For installation, use all screw halls and tap holes prepared on the linear servo motor.
When the equipment has been stored for an extended period of time, consult Mitsubishi.

torque.
The cables such as power cables deriving from the primary side (coil) cannot stand the long-term flexing
action. Avoid the flexing action by fixing to the movable part, etc. Also, use the cable that stands the longterm flexing action for the wiring to the servo amplifier.
A- 5
(3) Test run adjustment
CAUTION
Before operation, check the parameter settings. Improper settings may cause some machines to perform
unexpected operation.
The parameter settings must not be changed excessively. Operation will be insatiable.
(4) Usage
CAUTION
Provide an external emergency stop circuit to ensure that operation can be stopped and power switched
off immediately.
Any person who is involved in disassembly and repair should be fully competent to do the work.
Before resetting an alarm, make sure that the run signal of the servo amplifier is off to prevent an accident.
A sudden restart is made if an alarm is reset with the run signal on.
Do not modify the equipment.
Use a noise filter, etc. to minimize the influence of electromagnetic interference, which may be caused by
electronic equipment used near the servo amplifier.
Burning or breaking a servo amplifier may cause a toxic gas. Do not burn or break a servo amplifier.
Use the servo amplifier with the specified linear servo motor.
(5) Corrective actions
CAUTION
When it is assumed that a hazardous condition may take place at the occur due to a power failure or a
product fault, use a linear servo motor with electromagnetic brake or an external brake mechanism for the
purpose of prevention.
When any alarm has occurred, eliminate its cause, ensure safety, and deactivate the alarm before
restarting operation.
When power is restored after an instantaneous power failure, keep away from the machine because the
machine may be restarted suddenly (design the machine so that it is secured against hazard if restarted).
(6) Maintenance, inspection and parts replacement
CAUTION
When the linear servo motor is damaged, it must be replaced. Contact Mitsubishi Electric System &
Service Co., Ltd.
With age, the electrolytic capacitor of the servo amplifier will deteriorate. To prevent a secondary accident
due to a fault, it is recommended to replace the electrolytic capacitor every 10 years when used in general
environment.
Please consult our sales representative.
A- 6
(7) Disposal
CAUTION
The linear servo motor uses a strong magnet on the secondary side. Therefore, not only the operators but
also the people around the work place must use abundance of caution when the linear servo motor is
disassembled or discarded. For example, one who uses a medical device like a pacemaker must keep
away from the machine.
The permanent magnet on the secondary side makes the magnetic bodies (primary side [coil] and
secondary side [magnet]) generate suction. Use special caution with the handling of the secondary side
which is demagnetized before/after disassembly.
When the linear servo motor is disassembled or discarded, do not put magnetic bodies (including the
primary side [coil], the other secondary sides [magnet] and tools) close to the secondary side (magnet).
The secondary side (magnetic) can have as double suction power as mounted normally, which may cause
a serious injury. In all cases, pay full attention to the ambience of workplace to avoid this.
CAUTION
A suction power is generated when magnetic bodies (including tools) are put near the permanent magnet
on the secondary side. Be sure to use nonmagnetic tools for the disassembly and disposal of the linear
servo motor or the work around it. These are required for the improvement of workability and safety
ensuring.
The personnel who work for the disassembly or disposal of the linear servo motor or those who are
around the workplace must not work wearing electronic devices (watch, calculator, personal computer,
etc.) and magnetic recording media (IC card, magnetic card, floppy disc, etc.) and must not bring them
around the secondary side (magnet). Magnetic influence may cause the operation failure or malfunction.
The servo amplifier and the primary side (coil) of the linear servo motor must be discarded in accordance
with "About processing of waste".
Since the secondary side (magnet) of the linear servo motor uses the permanent magnet, demagnetize
the entire secondary side (magnet) by heating over 300 (572 ), then discard in accordance with "About
processing of waste".
Do not touch the secondary side after the demagnetization of the secondary side (magnet) by heating
over 300 (572 ) until it becomes cool enough. Otherwise, you may get burnt.
(8) General instruction
To illustrate details, the equipment in the diagrams of this Specifications and Instruction Manual may have

Handling of Linear Servo Motor
1. Magnetic suction
The secondary side of the linear servo motor contains a strong permanent magnet, so a magnetic suction
power (power by which a magnet attracts magnetic bodies) is generated toward magnetic bodies such as iron.
Magnetic suction
This magnet suction is always acting whether the motor power is turned ON/OFF.
Always acting whether
the power is ON/OFF
Magnet face side
Mount (yoke) face side
The magnetic fluxes generating from the permanent magnet disperse in the air from the magnet face side
(facing the primary side), and most of them do not leak to the mount (yoke) side for its structure.
Because of this, a magnetic suction power occurs on the magnet face side of the secondary side and does not
on the mount (yoke) face side.

The permanent magnet used for the linear servo motor is very strong.
When an A4-sized iron sheet is fully attracted, the magnetic suction power becomes as high as 2.5t. Use
abundance of caution with the handling.

2. For the safety
The magnetic suction power is in inverse proportion to square of the distance to a magnetic body, so it
drastically increases when the distance becomes small.
When mounting the secondary side of the linear side motor, ensure the sufficient distance from the magnetic
bodies around it and securely fix those magnetic bodies.

1. FUNCTIONS AND CONFIGURATION
1. FUNCTIONS AND CONFIGURATION
1.1 Introduction
In fields of semiconductor and liquid crystal related equipment, installed machine, etc. with strong demands
for high accuracy, high-speed and high efficiency, the system using the linear servo motor for drive shaft is
increasing. Since the linear servo system can obtain the characteristics of the high-speed and the high
acceleration/deceleration greater than the ball screw drive system, and does not have a ball screw wear
which is a weak point in the ball screw drive system, it can extend the life of the equipments. In addition, a
response error does not occur and so the high accuracy system can be established.
The following shows the differences between the linear servo motor and the rotating servo motor.

Description
Merely setting a home position once makes home position return
unnecessary at every power-on.
You can switch between gains during rotation and gains during stop or use
an external signal to change gains during operation.
This function suppresses vibration at the arm end or residual vibration.
Servo amplifier detects mechanical resonance and sets filter characteristics
automatically to suppress mechanical vibration.
Suppresses high-frequency resonance which occurs as servo system
response is increased.
Analyzes the frequency characteristic of the mechanical system by simply
connecting a MR Configurator-installed personal computer and servo
amplifier.
MR Configurator MRZJW3-SETUP221E is necessary for this function.
Can simulate machine motions on a personal computer screen on the basis
of the machine analyzer results.
MR Configurator MRZJW3-SETUP221E is necessary for this function.
Personal computer changes gains automatically and searches for overshootfree gains in a short time.
MR Configurator MRZJW3-SETUP221E is necessary for this function.

2. LINEAR SERVO MOTOR
2. LINEAR SERVO MOTOR
The secondary side of the linear servo motor contains a strong permanent magnet. The wrong handling may
cause serious accidents, which is extremely dangerous. Please read this chapter carefully beforehand and use
it correctly.
2.1 Handling
2.1.1 General instructions
The linear servo motor uses a strong magnet on the secondary side. Therefore,
not only the linear servo motor installation operators but also the machine
operators must use abundance of caution. For example, one who uses a medical
device like a pacemaker must keep away from the machine.
WARNING
The permanent magnet on the secondary side makes the magnetic bodies
generate suction. Use caution with accidents so as not to get your hand stuck.
The performance is not guaranteed if the specified servo amplifier and linear
servo motor are not combined. If used with unspecified combination, the servo
amplifier or linear servo motor may be damaged. Depending on the case, it can
be out of control and operate unexpectedly, resulting in extremely dangerous
condition.
The linear servo motor installation operators and machine operators must not
work wearing electronic devices (watch, calculator, personal computer, etc.) and
magnetic recording media (IC card, magnetic card, floppy disc, etc.) and must not
bring them around a magnetic. The magnetic influence may cause the operation
failure or malfunction.
The protection method of the linear servo motor is IP00. Take necessary
measures against dust, oil, etc. (Refer to section 2.1.2 Installation direction.)
When the linear servo motor is damaged, it must be replaced. Contact Mitsubishi
Electric System & Service Co., Ltd.
CAUTION
When the protective function is operated, turn off the power immediately and
eliminate its cause, and then turn it on again. If the linear servo motor is continued
operating without eliminating the cause, it may run unexpectedly and results in a
damage and injury.
Take safety measures, e.g. provide covers, to prevent accidental contact of
hands and parts (cables, etc.) with the servo amplifier heat sink, regenerative
resistor, linear servo motor, etc. since they may be hot while power is on or for
some time after power-off. Their temperatures may be high and you may get
burnt or a parts may damaged.
The primary side (coil) and secondary side (magnet) may be damaged by a fall or
shock.
2- 1
2. LINEAR SERVO MOTOR
2.1.2 Instructions on design
CAUTION
The dynamic brake can be applied to the servo amplifier, but the coasting distance
becomes longer when the moving body is heavy or when the speed is high. It may
result in crashing into the stroke edge, which is highly dangerous. Install the anticrash mechanism such as an air brake or an electric/mechanical stopper such as a
shock absorber to reduce the shock of movable parts. (No linear servo motor with
an electromagnetic brake is available.)
The magnetic suction power acting between the primary side (coil) and the
secondary (magnet) is always acting even when the motor power is not turned on.
Because of this, the machine must be designed to be rigid enough to resist the
magnetic suction power and maintain the accuracy.
The running load by friction increases in proportion to the increase of the magnetic
suction power, so the design must be made to decrease as much friction as
possible, for example, by mounting guides with high accuracy.
Do not use for vertical motion applications since magnetic poles cannot be
detected with a vertical application.
Install the linear servo motor the way in which the thrust acts on the gravity center
of the movable part. When the thrust does not act on the gravity center of the
movable part, the moment is generated.
Design the mounting dimensions to be satisfied for the primary side (coil) and
secondary side (magnet).
The cables such as power cables deriving from the primary side (coil) cannot stand
the long-term flexing action. Avoid the flexing action by fixing to the movable part,
etc. Also, use the cable that stands the long-term flexing action for the wiring to the
servo amplifier.
Magnetic chips such as iron fragments can be attached to the permanent magnet
on the secondary side, which may cause a malfunction. In the environment like
this, take measures against the attachment and entry of magnetic chips.
When the linear servo motor is operated over a long term under the condition
where water for cutting or lubrication oil is splashed or where oil mist or dew
condensation occurs due to supercooling or high humidity, insulation deterioration
or other failures may be caused. Prevent the linear servo motor from oil and dust
with a cover and take measures against dew condensation.
More careful measures against oil and dust must be taken for the linear encoder
than the linear servo motor. For details, please contact the linear encoder
manufacturer individually.
The moving direction of the linear servo motor and linear encoder must be
matched. Otherwise, the motor may run unexpectedly.
When two or more secondary side (magnet) is mounted, set the mounting screw
accumulative pitch tolerance within 0.2mm. Clearance may be left between the
secondary sides (magnets) depending on the mounting method and the numbers.
Do not hit the primary side (coil) on the stopper. The primary side may be
damaged. Design the machine so that the stopper is hit on the top table attached to
the primary side (coil).
2- 2
2. LINEAR SERVO MOTOR
POINT
To execute the high accuracy positioning, ensure as much rigidity of machine
as possible and make the machine resonance point higher.
Make the moving parts as light as possible and make the base parts heavier
and sturdier.
As the operation and accuracy of machine could have an adverse effect,
design it in order to make the thrust center of the linear servo motor closer to
a moving body's gravity center.
When the mounting rigidity of the linear encoder is not enough, machine
vibration, etc. affect the feedback signal, and the desired performance may
not be satisfied. As it is also the same case when the linear encoder is
susceptible to electric noise, set up and mount the linear encoder so that it is
affected by as little vibration and noise as possible.
Establish the structure to sustain the high-speed and the high acceleration
and deceleration.
2.1.3 Instructions on installation operation
Under the packaged condition (cardboard) delivered from our company, the
magnet on the secondary side does not have a serious effect on the outside.
Before mounting to the machine, however, magnetic bodies (including tools) must
be kept away from the secondary side (magnetic). The secondary side (magnetic)
can have as double suction power as mounted normally, which may cause a
serious injury. To avoid this, pay full attention to the ambience of workplace.
Magnetic body such as iron
WARNING
Secondary side (magnet)
Magnetic suction power: Max. 5 ton
The permanent magnet on the secondary side makes the magnetic bodies
generate suction, which may cause troubles such as having hands pinched, etc.
For the installation of the linear servo motor and the work around it, be sure to use
nonmagnetic tools. These are required for the improvement of workability and
safety ensuring. Use special caution with mounting the primary side (coil) after the
secondary side (magnet) has mounted. Use the screw which strength must be a
high tensile strength steel level of SCM435 for its material and the lower yield point
2
900 [N/mm ] or more. (Example) Explosion-proof beryllium copper alloy safety
tools: Manufactured by NGK Insulators, Ltd.
CAUTION
Do not install the servo motor, linear servo motor and regenerative resistor on or
near combustibles. Otherwise a fire may cause.
Securely attach the linear servo motor to the machine. If attach insecurely, it may
come off during operation.
Install the servo amplifier in a load-bearing place in accordance with the
Instruction Manual.
2- 3
2. LINEAR SERVO MOTOR
CAUTION
Do not subject the servo amplifier and linear servo motor to drop impact or shock
loads as they are precision equipment.
Do not install or operate a faulty servo amplifier and linear servo motor.
Use the equipment within the specified environmental condition range. (For the
environmental condition, refer to section 1.2.)
Tap holes on the linear servo motor are for machine installation. Do not use for
other purposes.
Do not touch the linear servo motor with wet hands.
For installation, use all screw halls and tap holes prepared on the linear servo
motor.
When two or more secondary side (magnet) is mounted, set the mounting screw
accumulative pitch tolerance within 0.2mm. Clearance may be left between the
secondary sides (magnets) depending on the mounting method and the numbers.
2.1.4 Instructions on storage
CAUTION
Do not climb or stand on servo equipment. Do not put heavy objects on
equipment.
Be sure to follow the storage conditions (ambient temperature and humidity, etc.).
Store the product in the environment where the rain water is prevented from
splashing on and dust, oil, and chemical materials from attaching on.
Do not strike servo amplifier or linear servo motor.
Do not modify the linear servo motor.
When the equipment has been stored for an extended period of time, consult
Mitsubishi.
2.2 Inspection items
WARNING
Before starting maintenance and/or inspection, turn off the power and wait for 15
minutes or more until the charge lamp turns off. Then, confirm that the voltage
between P( ) and N( ) is safe with a voltage tester and others. Otherwise, an
electric shock may occur. In addition, always confirm from the front of the servo
amplifier whether the charge lamp is off or not.
Any person who is involved in inspection should be fully competent to do the work.
Otherwise, you may get an electric shock. For repair and parts replacement,
contact your safes representative.
POINT
When executing a megger test (insulation resistance test), disconnect the
servo amplifier. Otherwise, a fault may occur.
Do not disassemble and/or repair the equipment on customer side.
The molded resin of the linear servo motor may lose the color. Though a fault
may not occur only for losing the color, make inspections.
It is not until the linear servo motor is mounted in equipment (built-in) that it has functions as motor. As the
protection method is IP00, it is recommended to make inspections and clean periodically.

2. LINEAR SERVO MOTOR
2.2.1 Inspections on primary side (coil)
(1) Attachment of water and oil
Check that the primary side (coil) and secondary side (magnet) have not got wet with water and oil. When
the linear servo motor has got wet, the insulation on the primary side (coil) is deteriorated, which may cause
failure. Make sure to establish the mechanical structure in which water and oil are not attached to the linear
motor.
(2) Molded resin
Check for missing or cracks of the molded resin on the primary side (coil). As the insulation deterioration
and such may cause failure when missing or cracks are found in the molded resin on the primary side (coil),
replace the primary side (coil).
(3) Scratches of primary side (coil) facing secondary side (magnet)
Check the scratches of the primary side (coil) facing the secondary side (magnet). When the primary side
(coil) facing the secondary side (magnet) has scratches, replace the primary side (coil). When a foreign
matter is caught in the empty clearance between the primary side (coil) and the secondary side (magnet), a
scratch occurs on the primary side (coil). In such case, take away the corresponding matter and establish
the mechanical structure which does not catch such matters.
However, if the scratches of the primary side (coil) facing the secondary side (magnet) result in no more
than the protective coating peeled off, they can be repaired.
(4) Loose mounting screws
Check for loose mounting screws on the primary side (coil). When the mounting screws on the primary side
(coil) are loose, tighten the corresponding screws.
(5) Scratches and cracks of linear servo motor cables
Check for scratches and cracks of the linear servo motor cables. If the linear servo motor cables have any
scratches or cracks, replace the corresponding cables. Especially when the cables are moved, make
inspections periodically.

failure. Make sure to establish the mechanical structure in which water and oil are not attached to the linear
motor.
(2) Exposure and lift of magnet
Check for the exposure and lift of the magnet on the secondary side (magnet). If the magnet on the
secondary side (magnet) is exposed or lifted, replace the secondary side (magnet) immediately.
(3) Molded resin
(a) Check for missing or cracks of the mold resin on the secondary side (magnet). (a) When missing or
cracks are found in the molded resin on the secondary side (magnet), replace the secondary side
(magnet).
(b) Check for the scratches of the molded resin on the secondary side (magnet). When the magnet is
exposed by the scratches of the molded resin on the secondary side (magnet), replace the secondary
side (magnet). When a foreign matter is caught in the empty clearance between the primary side (coil)
and the secondary side (magnet), a scratch occurs on the secondary side (magnet). In such case, take
away the corresponding matter and establish the mechanical structure which does not catch such

2.4 Instructions for discarding the linear servo motor
Demagnetize the secondary side (magnet) of the linear servo motor by heating over 300
discard it in accordance with Law for Promotion of Effective Utilization of Resources.
(572 ), then
The linear servo motor uses a strong magnet on the secondary side. Therefore,
not only the operators but also the people around the work place must use
abundance of caution when the linear servo motor is disassembled or discarded.
For example, one who uses a medical device like a pacemaker must keep away
from the machine.
The permanent magnet on the secondary side makes the magnetic bodies
(primary side [coil] and secondary side [magnet]) generate suction.
Use special caution with the handling of the secondary side which is
demagnetized before/after disassembly.
WARNING
When the linear servo motor is disassembled or discarded, do not put magnetic
bodies (including the primary side [coil], the other secondary sides [magnet] and
tools) close to the secondary side (magnet). The secondary side (magnetic) can
have as double suction power as mounted normally, which may cause a serious
injury. In all cases, pay full attention to the ambience of workplace to avoid this.
Magnetic body such as iron
Secondary side (magnet)
Magnetic suction power: Max. 5 ton
A suction power is generated when magnetic bodies (including tools) are put near
the permanent magnet on the secondary side. Be sure to use nonmagnetic tools
for the disassembly and disposal of the linear servo motor or the work around it.
These are required for the improvement of workability and safety ensuring.
CAUTION
The personnel who work for the disassembly or disposal of the linear servo motor
or those who are around the workplace must not work wearing electronic devices
(watch, calculator, personal computer, etc.) and magnetic recording media (IC
card, magnetic card, floppy disc, etc.) and must not bring them around the
secondary side (magnet). Magnetic influence may cause the operation failure or
malfunction.
When the linear servo motor is disassembled or discarded, use cautions in order
to avoid accidents so as not to get your hand stuck.
Do not touch the secondary side after the demagnetization of the secondary side
(magnet) by heating over 300 (572 ) until it becomes cool enough. Otherwise,
you may get burnt.

(2) Mounting the secondary side (magnet)
WARNING
The linear servo motor uses a strong magnet on the secondary side. Therefore,
not only the servo motor installation operators but also the machine operators
must use abundance of caution. For example, one who uses a medical device like
a pacemaker must keep away from the machine.
When mounting the secondary side (magnet), use nonmagnetic tools.
CAUTION
When the additional secondary side (magnet) is mounted after one has been
already set, slide the additional secondary side (magnet) to mount in the specified
position after setting in the position away from the one already mounted as shown
in this section.
When two or more secondary side (magnet) is mounted, set the mounting screw
accumulative pitch tolerance within 0.2mm. Clearance may be left between the
secondary sides (magnets) depending on the mounting method and the numbers.
When using multiple secondary sides (magnets), arrange the name plates attached to the products on the
same side for keeping the layout of magnetic poles.
Name plate
In order to decrease the clearance between the secondary sides (magnets), mount them with the following
procedure.
Procedure 1. Securely fix with bolts the secondary side (magnet) to be a mounting standard.

(3) Mounting the primary side (coil)
To avoid the danger caused by suction, which is generated between the primary
side (coil) and the secondary side (magnet) by the permanent magnet, it is
recommended to mount the primary side (coil) in the position free from the
secondary side (magnet) as shown in this section.
CAUTION
When mounting the primary side (coil) over the secondary side (magnet)
unavoidably, use the material handling equipment such as crane which is fully
competent to sustain the load of suction, etc.
When sliding the primary side (coil) to move over the secondary side (magnet)
after setting, pay full attention to the suction generated.
Procedure 1. Mount a part of the secondary side (magnet).
Procedure 2. Mount the primary side (coil) in the position free from the secondary side (magnet).
Procedure 3. Move the primary side (coil) over the secondary side (magnet) mounted.
Confirm that the primary side (coil) does not contact the secondary side (magnet).
Procedure 4. Mount the rest of the secondary side (magnet).

(2) Mounting the secondary side (magnet)
WARNING
The linear servo motor uses a strong magnet on the secondary side. Therefore,
not only the servo motor installation operators but also the machine operators
must use abundance of caution. For example, one who uses a medical device like
a pacemaker must keep away from the machine.
When mounting the secondary side (magnet), use nonmagnetic tools.
CAUTION
When the additional secondary side (magnet) is mounted after one has been
already set, slide the additional secondary side (magnet) to mount in the specified
position after setting in the position away from the one already mounted as shown
in this section.
When two or more secondary side (magnet) is mounted, set the mounting screw
accumulative pitch tolerance within 0.2mm. Clearance may be left between the
secondary sides (magnets) depending on the mounting method and the numbers.
When using multiple secondary sides (magnets), arrange the name plates attached to the products on the
same side for keeping the layout of magnetic poles.
Caution name plate
In order to decrease the clearance between the secondary sides (magnets), mount them with the following
procedure.
Procedure 1. Securely fix with bolts the secondary side (magnet) to be a mounting standard.

2. LINEAR SERVO MOTOR
(2) Mounting the secondary side (magnet)
WARNING
The linear servo motor uses a strong magnet on the secondary side. Therefore,
not only the servo motor installation operators but also the machine operators
must use abundance of caution. For example, one who uses a medical device like
a pacemaker must keep away from the machine.
When mounting the secondary side (magnet), use nonmagnetic tools.
CAUTION
When the additional secondary side (magnet) is mounted after one has been
already set, slide the additional secondary side (magnet) to mount in the specified
position after setting in the position away from the one already mounted as shown
in this section.
When two or more secondary side (magnet) is mounted, set the mounting screw
accumulative pitch tolerance within 0.2mm. Clearance may be left between the
secondary sides (magnets) depending on the mounting method and the numbers.
When using multiple secondary sides (magnets), arrange the name plates attached to the products on the
same side for keeping the layout of magnetic poles.
Name plate
In order to decrease the clearance between the secondary sides (magnets), mount them with the following
procedure.
Procedure 1. Securely fix with bolts the secondary side (magnet) to be a mounting standard.
Secondary side (magnet) to be a mounting standard
Procedure 2. Set the secondary side (magnet) on the mounting face and fix it with bolts as temporary joint.

2. LINEAR SERVO MOTOR
Procedure 4. Securely fix with bolts the secondary side (magnet) fixed as temporary joint.
Secondary side (magnet) to be a mounting standard
(3) Mounting the primary side (coil)
To avoid the danger caused by suction, which is generated between the primary
side (coil) and the secondary side (magnet) by the permanent magnet, it is
recommended to mount the primary side (coil) in the position free from the
secondary side (magnet) as shown in this section.
CAUTION
When mounting the primary side (coil) over the secondary side (magnet)
unavoidably, use the material handling equipment such as crane which is fully
competent to sustain the load of suction, etc.
When sliding the primary side (coil) to move over the secondary side (magnet)
after setting, pay full attention to the suction generated.
Procedure 1. Mount a part of the secondary side (magnet).
Procedure 2. Mount the primary side (coil) in the position free from the secondary side (magnet).
Procedure 3. Move the primary side (coil) over the secondary side (magnet) mounted.
Confirm that the primary side (coil) does not contact the secondary side (magnet).
Procedure 4. Mount the rest of the secondary side (magnet).

4. SIGNALS AND WIRING
Any person who is involved in wiring should be fully competent to do the work.
WARNING
Before wiring, turn off the power and wait for 15 minutes or more until the charge
lamp turns off. Then, confirm that the voltage between P( ) and N( ) is safe with
a voltage tester and others. Otherwise, an electric shock may occur. In addition,
always confirm from the front of the servo amplifier whether the charge lamp is off
or not.
Ground the servo amplifier and the linear servo motor securely.
Do not attempt to wire the servo amplifier and linear servo motor until they have
been installed. Otherwise, you may get an electric shock.
The cables should not be damaged, stressed excessively, loaded heavily, or
pinched. Otherwise, you may get an electric shock.
Wire the equipment correctly and securely. Otherwise, the linear servo motor may
misoperate, resulting in injury.
Connect cables to correct terminals to prevent a burst, fault, etc.
Ensure that polarity (
,
) is correct. Otherwise, a burst, damage, etc. may occur.
The surge absorbing diode installed to the DC relay designed for control output
should be fitted in the specified direction. Otherwise, the signal is not output due to
a fault, disabling the forced stop (EM1) and other protective circuits.

Use a noise filter, etc. to minimize the influence of electromagnetic interference,
which may be given to electronic equipment used near the servo amplifier.
Do not install a power capacitor, surge suppressor or radio noise filter (FR-BIF
option) with the power line of the linear servo motor.
When using the regenerative resistor, switch power off with the alarm signal.
Otherwise, a transistor fault or the like may overheat the regenerative resistor,
causing a fire.
During power-on, do not open or close the motor power line. Otherwise, a
malfunction or faulty may occur.
Do not modify the equipment.
The cables such as power cables deriving from the primary side (coil) cannot stand
the long-term flexing action. Avoid the flexing action by fixing to the movable part,
etc. Also, use the cable that stands the long-term flexing action for the wiring to the
servo amplifier.

CAUTION
Always connect a magnetic contactor (MC) between the main circuit power supply
and L1, L2, and L3 of the servo amplifier, and configure the wiring to be able to shut
down the power supply on the side of the servo amplifier’s power supply. If a
magnetic contactor (MC) is not connected, continuous flow of a large current may
cause a fire when the servo amplifier malfunctions.
Use the trouble (ALM) to switch power off. Otherwise, a regenerative transistor
fault or the like may overheat the regenerative resistor, causing a fire.
POINT
Even if alarm has occurred, do not switch off the control circuit power supply.
When the control circuit power supply has been switched off, optical module
does not operate, and optical transmission of SSCNET communication is
interrupted. Therefore, the servo amplifier on the rear axis displays "AA" at
the indicator and turns into base circuit shut-off. The servo amplifier stops
with starting dynamic brake.
For details of each signal, refer to section 3.3 of the MR-J3- B Servo
Amplifier Instruction Manual.
Wire the power supply/main circuit as shown below so that power is shut off and the servo-on command turned
off as soon as an alarm occurs, a servo forced stop is made valid, or a controller forced stop is made valid. A
no-fuse breaker (NFB) must be used with the input cables of the main circuit power supply.

0: Linear servo motor positive direction and linear encoder increase direction
1: Linear servo motor positive direction and linear encoder decrease direction
(1) Parameter setting method
(a) Confirm the positive direction of linear servo motor the relationship of the moving direction of linear
servo motor to commands is determined by the setting of the parameter No.PA14 as follows.

(b) Confirm the increase direction of linear encoder.
(c) If the positive direction of the linear servo motor matches with the increase direction of linear encoder,
set the parameter No.PC27 to "
0". If not, set the parameter to "
1".
(2) Confirmation method
Confirm the positive direction of linear servo motor and the increase direction of linear encoder using the
following procedure.
(a) Move the linear servo motor manually to the positive direction in the servo off status.
(b) Confirm the motor speed (positive and negative) at that time using MR Configurator.
5- 2
5. OPERATION AND FUNCTIONS
(c) If the parameter No.PC27 is set to "
0" and the positive direction of linear servo motor matches
with the increase direction of linear encoder, the motor speed will be a positive value by making the
linear servo motor work to the positive direction. If the positive direction of linear servo motor does not
match with the increase direction of linear encoder, the motor speed will be a negative value. If the
parameter No.PC27 is set to "
1" and the positive direction of linear servo motor matches with the
increase direction of linear encoder, the motor speed will be a negative value by making the linear servo
motor work to the positive direction.
5.1.3 Setting of the linear encoder resolution
Set the ratio to the linear encoder resolution using the parameter No.PS02 (Linear encoder resolution setting
numerator) and parameter No.PS03 (Linear encoder resolution setting denominator).
POINT
When using this parameter, turn the power off once after setting the
parameter No.PA19 to "
D", and then turn it on again.
After setting this parameter, turning the power off once and then turning it on
again makes the setting valid.
(1) Parameter setting
Set the value as the following equation.
Parameter No.PS02 (Linear encoder resolution setting numerator)
Parameter No.PS03 (Linear encoder resolution setting denominator)
Linear encoder resolution [

5. OPERATION AND FUNCTIONS
5.2 Settings of the magnetic pole detection and the magnetic pole detection voltage level
Make sure to perform the magnetic pole detection before starting the positioning operation in order to match
the positional relationship between the linear servo motor and the linear encoder.
5.2.1 Preparation for the magnetic pole detection
For the magnetic pole detection, the test operation mode (positioning operation) of MR Configurator is used.
Turn the power of servo amplifier off and set the test operation select switch (SW2-1) as shown below. By
turning the power on, it switches to the test operation mode.

5.2.2 Magnetic pole detection
WARNING
Note that the magnetic pole detection is automatically started simultaneously with
turning ON the servo-on command.
CAUTION
If the magnetic pole detection is not executed properly, the linear servo motor
may run unexpectedly.
5- 4
5. OPERATION AND FUNCTIONS
POINT
Establish the machine configuration using the stroke limits (FLS and RLS). If
the stroke limits (FLS and RLS) do not exist, it may cause the machine
damage by a collision.
At the magnetic pole detection, it is not predictable whether it moves to the
positive direction or the positive direction.
Setting the parameter No.PS09 (Magnetic pole detection voltage level) may
cause the occurrence of overload, overcurrent, magnetic pole detection
alarm, etc.
When performing the positioning operation from the positioning controller, set
the sequence which confirms the normal completion of magnetic pole
detection and the servo-on status, then outputs the positioning command. If
outputting the positioning command before the Ready (RD) turns ON, the
command may not be accepted or the servo alarm may occur.
After the magnetic pole detection, check the accuracy of position with the test
operation (positioning operation) of MR Configurator.
If a gap is generated to the positional relationship between the linear encoder
and the linear servo motor when using the absolute position linear encoder,
carry out the magnetic pole detection again.
The accuracy of magnetic pole detection will be improved by being operated
in the no-load condition.
The servo alarm may occur when the linear encoder is not mounted properly
or when the setting (parameter Nos. PS02 and PS03) of linear encoder
resolution or the setting value of parameter No.PS09 (magnetic detection
voltage level) is not correct.
On the machine of which friction becomes 30% or more than the rated thrust,
it may not operate properly after the magnetic pole detection.
On the machine of which imbalance thrust becomes 20% or more than the
rated thrust at the horizontal axis, it may not operate properly after the
magnetic pole detection.
5- 5
5. OPERATION AND FUNCTIONS
For the following cases, the magnetic pole detection is required.
(a) When using the incremental linear encoder (Refer to (1) in this section)
(b) When using the absolute position linear encoder and matching with the cases indicated below (Refer to
(2) in this section)
At the system setup (at the first startup of equipment)
When the servo amplifier is replaced
When the linear servo motor (primary side (coil) or secondary side (magnet)) is replaced
When the linear encoder (scale or head) is replaced or its installation is changed
(1) For the incremental linear encoder
For the incremental linear encoder, the magnetic pole detection is required every time the power is turned
on. By turning ON the servo-on command from the controller after the power-on, the magnetic pole
detection is automatically carried out. Therefore, there is no need to set the parameters for executing the
magnetic pole detection.

If a gap is generated to the positional relationship between the linear encoder
and the linear servo motor when using the absolute position linear encoder,
carry out the magnetic pole detection again.

5.2.6 Magnetic pole detection under the specified condition
(1) Magnetic pole detection by the current detection 1
This method is used when the travel at the magnetic pole detection is expected to be smaller than the
magnetic pole detection (initial value) of the positioning detection method. The use of this method is limited
to when the load mass ratio (control gain) of equipment is clearly known.
(a) Procedures of magnetic pole detection by the current detection 1
1) If the control gains (Parameter Nos. PB06, PB07, PB08, PB09 and PB10) are known, set them in
advance. If they are not known, adjust the control gains using the following method a. or b.
a. Move the linear servo motor and execute the auto tuning (or normal gain adjustment), after the
magnetic pole detection of the positioning detection method.
b. Set the auto tuning to the manual mode 2 (Parameter No.PA08:
2), set the response level to
12 (Parameter No.PA09: Initial value), and then apply the value calculated from the machine
configuration to the load mass ratio (Parameter No.PB06) against the linear servo motor primary
side.
2) If the initial magnetic pole detection error (27) occurs at the magnetic pole detection, the following
conditions may be considered as causes. Check the setting values.
The setting value of the parameter No.PS09 (Magnetic pole detection voltage level) is too small.
The parameter No.PC27 (Encoder pulse count polarity) is not set correctly.
The parameter Nos. PS02 and PS03 (Linear encoder resolution setting) are not set correctly.
3) If the overcurrent alarm occurs during the magnetic pole detection, make the magnetic pole detection
voltage level (Parameter No.PS09) smaller five by five. If the overload 1 (59) and overload 2 (51)
occur, make the current detection method oscillation setting (Parameter No.PS11) smaller 10 by 10.
4) If the machine resonates during the magnetic pole detection, lower the response level (Parameter
No.PA09) of the auto tuning or use the machine resonance filter (Parameter Nos. PB13 and PB15).

End
(2) Magnetic pole detection by the current detection 2
For the positioning detection method 1 and current detection method 1, this method is used in the machine
configuration with little friction such as an air guide when the magnetic pole detection cannot be completed
normally. The setting method is the same as that of the current detection method 1, but there is a possibility
that it moves a half distance of the maximum magnetic pole pitch at the magnetic pole detection.

5.3 Home position return
POINT
The incremental linear encoder and the absolute position linear encoder have
different home position reference positions at the home position return.
5.3.1 Incremental linear encoder
CAUTION
If the resolution or stop interval (the third digit of the parameter No.PS01) of the
linear encoder is too large, it is very dangerous since it may crash into the stroke
end.
POINT
When the servo system controller is a positioning module (QD75MH), the
operation will be different. Refer to (3) in this section.
(1) When the linear encoder home position (reference mark) exists in the home position return direction
The home position on the incremental linear encoder is a position per 1048576 pulses (changeable with the
third digit of the parameter No.PS01), which is based on the linear encoder home position (reference mark)
passed primarily after the start of home position return. Change the setting value of the parameter No.PS01

The positioning operation from the controller is basically the same as that of MR-J3- B.
For the system using the incremental linear encoder, however, the magnetic pole detection is automatically
performed at the first servo-on after turning the power on. For this reason, when performing the positioning
operation, configure the sequence which surely confirms the servo-on status as the inter lock condition of the
positioning command.
Also, some parameter settings and home position return operation varies depending on types of controllers.

5. OPERATION AND FUNCTIONS
(b) Initialization of the servo amplifier at the startup of linear servo
1) Before turning the power of servo amplifier on, write the servo parameter initial value, which is unique
to the linear servo, to the flash ROM of QD75MH referring to the sequence program example
shown in (3) (a) in this section.
2) After completion of writing to the flash ROM, turn the power of servo amplifier on.
POINT
For the linear servo motor on the QD75MH , the parameter error (37) occurs
if the initialization of servo parameter is not executed.
Writing the initial value to the flash ROM is limited for only once at the startup.
There is no need to write to the flash ROM at the next power-on or later. If the
module write with GX Configurator-QP has been performed, however,
initialize the servo parameter again.
(c) When the magnetic pole detection limit switch is not used on the linear servo motor
For changing the setting of the parameter No.PD02, add the following program to the sequence

5.6 Functions
5.6.1 Linear servo control error detection function
POINT
For the linear servo control error detection function, the position and speed
deviation error detections are enabled as factory-set. (Parameter No.PS04:
3)
If the linear servo control gets unstable for some reasons, the linear servo motor may not operate properly. The
protective function for detecting this before happens and stopping the operation is the linear servo control error
detection function.
As the linear servo control error detection function, there are three types of detection methods: speed
deviation, position deviation and thrust deviation. An error is detected when each error detection function is
enabled with the setting of the parameter No.PS04 (Linear function selection 2). The detection level can be
changed with the parameter Nos. PS05, PS06 and PS07.

If there is a deviation larger than the setting value (1 to 200mm) of the parameter No.PS05 (Linear servo
control position deviation error detection level) after comparing the model feedback position 1) and the
feedback position 2) in Figure 5.1, the alarm (Linear servo control error 42) occurs, and the linear servo
motor stops. The initial value of parameter No.PS05 is 50mm. Change the setting value as necessary.

The initial value of parameter No.PS05 is 100%. Change the setting value as necessary.
(4) Detecting multiple deviation errors
Setting the parameter No.PS04 as shown below allows the linear servo motor to detect multiple deviation
errors. For the error detection methods, refer to (1) to (3) in this section.

5. OPERATION AND FUNCTIONS
5.6.2 Auto tuning function
The auto tuning function during the linear servo operation is the same as that of normal servo, but the
calculation method of load inertia moment ratio (J ratio) is different. The load inertia moment ratio (J ratio) on
the linear servo is a mass ratio calculated dividing the load mass by the mass of linear servo motor primary
side (coil).
Example) Linear servo motor primary side (coil) mass
Load mass (excluding the motor primary side (coil) mass)
Mass ratio
2kg
4kg
4/2
Twice
Other parameters set with the auto tuning function are the same as those of MR-J3- B servo amplifier. For
details, refer to chapter 6 of the MR-J3- B Servo Amplifier Instruction Manual.
POINT
If not meeting with the following conditions, the auto tuning mode 1 may not
operate properly.
The acceleration/deceleration time constant which takes less than 5s to
reach to 2,000mm/s
The linear servo motor speed is 150mm/s or faster.
The load mass ratio to the mass of linear servo motor primary side (coil) is
100 times or smaller.
The acceleration/deceleration thrust is 10% or less of the rated thrust.
5.6.3 Machine analyzer function
The machine analyzer function of MR Configurator is the same as that of MR-J3-
B.
POINT
Make sure to carry out the machine analyzer function after the magnetic pole
detection. If the magnetic pole detection is not executed, the function may not
operate properly.
The stop position at the completion of machine analyzer can be any position.
5.7 Absolute position detection system
When using the linear servo motor for the absolute position detection system, the absolute position linear
encoder is required. The backup of absolute position data is performed by the linear encoder. For this reason,
there is no need to mount a battery (MR-J3BAT) for encoder on the servo amplifier. Also, the alarm (25) and
warnings (92, 9F and E3) related to the absolute position are not detected.

Alarms
When an fault occurs during operation, the corresponding alarm or warning is displayed.
If any alarm has occurred, refer to section 7.2, and section 8.2 of the MR-J3- B Servo Amplifier Instruction
Manual; if any warning has occurred, refer to section 7.3, and section 8.3 of the MR-J3- B Servo Amplifier
Instruction Manual, and take the appropriate action. When an alarm occurs, ALM turns OFF.
After its cause has been removed, the alarm can be deactivated in any of the methods marked

7.2 Remedies for alarms
CAUTION
When any alarm has occurred, eliminate its cause, ensure safety, then reset the
alarm, and restart operation. Otherwise, injury may occur.
As soon as an alarm occurs, mark servo-off and power off the main circuit and
control circuit.
POINT
When any of the following alarms has occurred, do not deactivate the alarm
and resume operation repeatedly. To do so will cause the servo amplifier/linear
servo motor to fail. Remove the cause of occurrence, and leave a cooling time
of more than 30 minutes before resuming operation. To protect the main circuit
elements, any of these servo alarms cannot be deactivated from the servo
system controller until the specified time elapses after its occurrence. Judging
the load changing condition until the alarm occurs, the servo amplifier
calculates this specified time automatically.
Regenerative error (30)
Overload 1 (50)
Overload 2 (51)
The alarm can be deactivated by switching power off, then on or by the error
reset command CPU reset from the servo system controller. For details, refer
to section 8.1.
When an alarm occurs, the trouble (ALM) switches off and the dynamic brake is operated to stop the linear
servo motor. At this time, the display indicates the alarm No.
The linear servo motor comes to a stop. Remove the cause of the alarm in accordance with this section. Use
the MR Configurator to refer to a factor of alarm occurrence.

allowed, it may result in crashing into the stroke edge, which is highly dangerous.
Install the anti-crash mechanism such as an air brake or an electric/mechanical
stopper such as a shock absorber to reduce the shock of movable parts. No linear
servo motor with an electromagnetic brake is available.

App. 3 Capacity selection of linear servo motor
App. 3.1 Selection of linear servo motor
Select a linear servo motor according to the purpose of the machine for which it is installed. When the machine
on which a linear servo motor is installed is not compatible with the motor, the performance of the linear servo
motor cannot be fully got out of and furthermore it becomes difficult to perform the gain adjustment. Select a
linear servo motor correctly with the full understanding of the characteristics of the linear servo motor with
reference to this section.
(1) Maximum feed speed
Maximum feed speed of the linear servo motor of each series is 2m/s. Note, however, that 2m/s cannot be
reached depending on the selected linear encoder.
App. - 3
APPENDIX
(2) Selection of the primary side (coil) (Logical value)
The linear servo motor has the output area (maximum thrust) that can be used only for a short time such as
acceleration/deceleration aside from the continuous thrust and that can provide about triple thrust of the
rated.
Calculate the continuous effective load thrust and the necessary maximum thrust from all data of the
machine and the operation pattern, and select a linear servo motor applicable to those results. The
following indicates the selection example for the operation pattern of line acceleration/deceleration.
V : Feed speed [m/s]
M1 : Load mass [kg]
M2 : Weight on linear servo motor primary side
Fma : Acceleration time thrust [N]
Ff : Load power [N]
(Including friction, imbalance, cable bear)
Fmd : Deceleration time thrust [N]

t2 : Constant speed time [s]
t3 : Deceleration time [s]
t0 : 1 cycle time [s]
