Securely attach the servo motor to the machine. If attach insecurely, the servo motor may come off during
operation.
Be sure to measure the motor vibration level with the servo motor mounted to the machine when checking
the vibration level. A great vibration may cause the early damage of a bearing, encoder, brake, and
reduction gear. The great vibration may also cause the poor connector connection or bolt looseness.
For the gain adjustment at the equipment startup, check the torque waveform and the speed waveform by
using a measurement device, and then check that no vibration occurs. If the vibration occurs due to high
gain, the vibration may cause the early damage of the servo motor.
Take safety measures, e.g. provide covers, to prevent accidental access to the rotating parts of the servo
motor during operation.
Never hit the servo motor or shaft, especially when coupling the servo motor to the machine. The encoder
may become faulty.
Do not subject the servo motor shaft to more than the permissible load. Otherwise, the shaft may break.

(6) Storage for servo motor
CAUTION
Note the following points when storing the servo motor for an extended period of time (guideline: three or
more months).
Always store the servo motor indoors in a clean and dry place.
If it is stored in a dusty or damp place, make adequate provision, e.g. cover the whole product.
If the insulation resistance of the winding decreases, reexamine the storage method.
Though the servo motor is rust-proofed before shipment using paint or rust prevention oil, rust may be
produced depending on the storage conditions or storage period.
If the servo motor is to be stored for longer than six months, apply rust prevention oil again especially to
the machined surfaces of the shaft, etc.
Before using the product after storage for an extended period of time, hand-turn the motor output shaft to
confirm that nothing is wrong with the servo motor. (When the servo motor is equipped with a brake,
make the above check after releasing the brake with the brake power supply.)
When the equipment has been stored for an extended period of time, please contact your local sales
office.
(7) Maintenance, inspection and parts replacement
CAUTION
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.
For replacement, please contact your local sales office.
(8) General instruction
To illustrate details, the equipment in the diagrams of this Instruction Manual may have been drawn

1. FUNCTIONS AND CONFIGURATION
1. FUNCTIONS AND CONFIGURATION
1.1 Introduction
The Mitsubishi general-purpose AC servo MR-E Super has position control and internal speed control modes.
It can perform operation with the control modes changed, e.g. position/internal speed control. Hence, it is
applicable to wide range of fields such as precision positioning and smooth speed control of machine tools and
general industrial machines.
As this new series has the RS-232C or RS-422 serial communication function, a MR Configurator (servo
configuration software)-installed personal computer or the like can be used to perform parameter setting, test
operation, status display monitoring, gain adjustment, etc.
With real-time auto tuning, you can automatically adjust the servo gains according to the machine.
The MR-E Super servo motor is equipped with an incremental position encoder that has the resolution of
131072 pulses/rev to ensure high precision positioning.
(1) Position control mode
An up to 1Mpps high-speed pulse train is used to control the speed and direction of a motor and execute
precision positioning of 131072 pulses/rev resolution.
The position smoothing function provides a choice of two different modes appropriate for a machine, so a
smoother start/stop can be made in response to a sudden position command.
A torque limit is imposed on the servo amplifier by the clamp circuit to protect the power transistor in the
main circuit from overcurrent due to sudden acceleration/deceleration or overload. This torque limit value
can be changed to any value with the parameter.
(2) Internal speed control mode
The parameter-driven internal speed command (max. 7 speeds) is used to control the speed and direction
of a servo motor smoothly.
There are also the acceleration/deceleration time constant setting in response to speed command, the
servo lock function at a stop time.

(3) Others
When using heat generating equipment such as the regenerative option, install them with full consideration
of heat generation so that the servo amplifier is not affected.
Install the servo amplifier on a perpendicular wall in the correct vertical direction.
2.3 Keep out foreign materials
(1) When installing the unit in a control box, prevent drill chips and wire fragments from entering the servo
amplifier.
(2) Prevent oil, water, metallic dust, etc. from entering the servo amplifier through openings in the control box or
a cooling fan installed on the ceiling.
(3) When installing the control box in a place where there are much toxic gas, dirt and dust, conduct an air
purge (force clean air into the control box from outside to make the internal pressure higher than the
external pressure) to prevent such materials from entering the control box.
2.4 Cable stress
(1) The way of clamping the cable must be fully examined so that flexing stress and cable's own weight stress
are not applied to the cable connection.
(2) For use in any application where the servo motor moves, fix the cables (encoder, power supply, and brake)
with having some slack from the connector connection part of the servo motor to avoid putting stress on the
connector connection part. Use the optional encoder cable within the flexing life range. Use the power
supply and brake wiring cables within the flexing life of the cables.
(3) Avoid any probability that the cable insulator might be cut by sharp chips, rubbed by a machine corner or
stamped by workers or vehicles.
(4) For installation on a machine where the servo motor will move, the flexing radius should be made as large
as possible. Refer to section 12.4 for the flexing life.

3. SIGNALS AND WIRING
Any person who is involved in wiring should be fully competent to do the work.
Before wiring, turn off the power and wait for 15 minutes or more until the charge
lamp turns off. 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.
WARNING
Ground the servo amplifier and the servo motor securely.
Do not attempt to wire the servo amplifier and 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.
Insulate the connections of the power supply terminals to prevent an electric shock.
Wire the equipment correctly and securely. Otherwise, the servo motor may
operate unexpectedly, 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 emergency stop and other protective circuits.

Note 1. To prevent an electric shock, always connect the protective earth (PE) terminal (terminal marked
) of the servo amplifier to the
protective earth (PE) of the control box.
2. Connect the diode in the correct direction. If it is connected reversely, the servo amplifier will be faulty and will not output signals,
disabling the emergency stop and other protective circuits.
3. The emergency stop switch (normally closed contact) must be installed.
4. When starting operation, always connect the emergency stop (EMG) and forward rotation stroke end (LSN), reverse rotation stroke
end (LSP) with VIN. (Normally closed contacts)
5. Trouble (ALM) is connected with VIN in normal alarm-free condition (normally closed contact). When this signal is switched off (at
occurrence of an alarm), the output of the controller should be stopped by the sequence program.
6. When connecting the personal computer together with monitor outputs 1, 2, use the branch cable (MR-E3CBL15-P). (Refer to
section 13.1.3)
7. The pins with the same signal name are connected in the servo amplifier.
8. This length applies to the command pulse train input in the open collector system. It is 10m or less in the differential line driver
system.
9. Use MRZJW3-SETUP154E or 154C.
10. Externally supply 24VDC
10 , 200mA power for the interface. 200mA is a value applicable when all I/O signals are used.
Reducing the number of I/O points decreases the current capacity. Refer to the current necessary for the interface described in
section 3.6.2. Connect the external 24VDC power supply if the output signals are not used.

3. SIGNALS AND WIRING
Note 1. To prevent an electric shock, always connect the protective earth (PE) terminal (terminal marked
) of the servo amplifier to the
protective earth (PE) of the control box.
2. Connect the diode in the correct direction. If it is connected reversely, the servo amplifier will be faulty and will not output signals,
disabling the emergency stop and other protective circuits.
3. The emergency stop switch (normally closed contact) must be installed.
4. When starting operation, always connect the emergency stop (EMG) and forward rotation stroke end (LSN), reverse rotation stroke
end (LSP) with VIN. (Normally closed contacts)
5. Trouble (ALM) is connected with VIN in normal alarm-free condition (normally closed contact). When this signal is switched off (at
occurrence of an alarm), the output of the controller should be stopped by the sequence program.
6. When connecting the personal computer together with monitor outputs 1, 2, use the branch cable (MR-E3CBL15-P). (Refer to
section 13.1.3)
7. The pins with the same signal name are connected in the servo amplifier.
8. This length applies to the command pulse train input in the differential line driver system.
It is 2m or less in the open collector system.
9. Use MRZJW3-SETUP154E or 154C.
10. To enhance noise immunity, connect LG and pulse output COM.
11. Externally supply 24VDC
10 , 200mA power for the interface. 200mA is a value applicable when all I/O signals are used.
Reducing the number of I/O points decreases the current capacity. Refer to the current necessary for the interface described in
section 3.6.2. Connect the external 24VDC power supply if the output signals are not used.

Proportion control
PC
Connect PC-VIN to switch the speed amplifier from the proportional integral
type to the proportional type.
If the servo motor at a stop is rotated even one pulse due to any external
factor, it generates torque to compensate for a position shift. When the
servo motor shaft is to be locked mechanically after positioning completion
(stop), switching on the proportion control signal (PC) upon positioning
completion will suppress the unnecessary torque generated to compensate
for a position shift.
When the shaft is to be locked for a long time, set the internal torque limit 1
and 2 (parameter No.28 and 76) to make the torque less than the rated
torque at the same time of turning ON the proportion control signal.

the alarm and also allow about 30 minutes for cooling before resuming operation.
(2) Regenerative error
If operation is repeated by switching power off, then on to reset the regenerative (AL.30) alarm after
its occurrence, the external regenerative resistor will generate heat, resulting in an accident.
(3) Instantaneous power failure
Undervoltage (AL.10) occurs when the input power is in either of the following statuses.
A power failure of the control circuit power supply continues for 60ms or longer, then the power
restores.

3.7 Input power supply circuit
Always connect a magnetic contactor 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 is not connected, continuous flow of a large current may cause
a fire when the servo amplifier malfunctions.
CAUTION
Use the trouble (ALM) to switch power off. Otherwise, a regenerative transistor
fault or the like may overheat the regenerative resistor, causing a fire.
For main circuit power supply of servo amplifier, check the model of servo amplifier
and input the correct voltage. If a voltage exceeding the upper limit shown in the
servo amplifier input voltage specification is input, the servo amplifier malfunctions.
POINT
The power supply connector (CNP1) is optional. Purchase it without fail.

3.7.3 Power-on sequence
(1) Power-on procedure
1) Always wire the power supply as shown in above section 3.7.1 using the magnetic contactor with the
power supply (three-phase 200V: L1, L2, L3, single-phase 230V: L1, L2). Configure up an external
sequence to switch off the magnetic contactor as soon as an alarm occurs.
2) The servo amplifier can accept the servo-on (SON) 2s or more after the power supply is switched on.
Therefore, when SON is switched on simultaneously with the power supply, the base circuit will switch
on in about 1 to 2s, and the ready (RD) will switch on in further about 20ms, making the servo amplifier
ready to operate. (Refer to paragraph (2) in this section.)
3) When the reset (RES) is switched on, the base circuit is shut off and the servo motor shaft coasts.

(3) Emergency stop
CAUTION
Provide an external emergency stop circuit to ensure that operation can be
stopped and power switched off immediately.
Make up a circuit which shuts off power as soon as EMG-VIN are opened at an emergency stop. To ensure
safety, always install an external emergency stop switch across EMG-VIN. By disconnecting EMG-VIN, the
dynamic brake is operated to bring the servo motor to a sudden stop. At this time, the display shows the
servo emergency stop warning (AL.E6).
During ordinary operation, do not use the external emergency stop signal to alternate stop and run.
The servo amplifier life may be shortened.
Also, if the start signal is on or a pulse train is input during an emergency stop, the servo motor will rotate
as soon as the warning is reset. During an emergency stop, always shut off the run command.

CAUTION
Electromagnetic brake
The electromagnetic brake is provided for holding purpose and must not be used
for ordinary braking.
Before performing the operation, be sure to confirm that the electromagnetic brake
operates properly.
Do not use the 24VDC interface power supply for the electromagnetic brake.
Always use the power supply designed exclusively for the electromagnetic brake.
Otherwise, a fault may occur.
POINT
Refer to HF-KN/HF-SN Servo Motor Instruction Manual for specifications such
as the power supply capacity and operation delay time of the electromagnetic
brake.
Refer to HF-KN/HF-SN Servo Motor Instruction Manual for wiring diagrams.
Note the following when the servo motor equipped with electromagnetic brake is used.
1) Set "
1 " in parameter No.1 to make the electromagnetic brake interlock (MBR) valid. Note that
this will make the zero speed signal (ZSP) unavailable.
2) Do not share the 24VDC interface power supply between the interface and electromagnetic brake.
Always use the power supply designed exclusively for the electromagnetic brake.
3) The brake will operate when the power (24VDC) switches off.
4) While the reset (RES) is on, the base circuit is shut off. When using the servo motor with a vertical
shaft, use the electromagnetic brake interlock (MBR).
5) Switch off the servo-on signal after the servo motor has stopped.
3.8.2 Setting
1) Set "
1 " in parameter No.1 to make the electromagnetic brake interlock (MBR) valid.
2) Using parameter No.33 (electromagnetic brake sequence output), set a delay time (Tb) at servo-off from
electromagnetic brake operation to base circuit shut-off as in the timing chart shown in section 3.9.3.

Hence, set 26214 to CMX and 450 to CDV.
POINT
When "0" is set to parameter No.3 (CMX), CMX is automatically set to the
servo motor resolution. Therefore, in the case of Expression (5.2), setting 0 to
CMX and 2250 to CDX concludes in the following expression:
CMX/CDV=131072/2250, and electric gear can be set without the necessity to
reduce the fraction to the lowest term.
For unlimited one-way rotation, e.g. an index table, indexing positions will be
missed due to cumulative error produced by rounding off.
For example, entering a command of 36000 pulses in the above example
causes the table to rotate only the following:
36000
26214
450

Therefore, indexing cannot be done in the same position on the table.

(3) Instructions for reduction
The calculated value before reduction must be as near as possible to the calculated value after reduction.
In the case of (2) in this section, an error will be smaller if reduction is made to provide no fraction for CDV.

7. GENERAL GAIN ADJUSTMENT
POINT
For the gain adjustment, check that the machine operates below the maximum
torque of the servo motor. If the machine operates beyond the maximum torque
of the servo motor, the machine may perform unexpected operation such as the
machine vibration. Make the gain adjustment with a safety margin considering
characteristic differences of each machine. Generated torque during operation
must be the 90 maximum torque or less of the servo motor.
7.1 Different adjustment methods
7.1.1 Adjustment on a single servo amplifier
The gain adjustment in this section can be made on a single servo amplifier. For gain adjustment, first execute
auto tuning mode 1. If you are not satisfied with the results, execute auto tuning mode 2, manual mode 1 and

MR Configurator (servo configuration software) which operates on a personal computer.
Function
Description
Adjustment
Machine analyzer
With the machine and servo motor coupled,
the characteristic of the mechanical system
can be measured by giving a random
vibration command from the personal
computer to the servo and measuring the
machine response.
Gain search
Executing gain search under to-and-fro
positioning command measures settling
characteristic while simultaneously
changing gains, and automatically searches
for gains which make settling time shortest.
Response at positioning settling of a
machine can be simulated from machine
analyzer results on personal computer.
Machine simulation
7- 2
You can grasp the machine resonance frequency and
determine the notch frequency of the machine resonance
suppression filter.
You can automatically set the optimum gains in response
to the machine characteristic. This simple adjustment is
suitable for a machine which has large machine
resonance and does not require much settling time.
You can automatically set gains which make positioning
settling time shortest.
You can optimize gain adjustment and command pattern
on personal computer.
7. GENERAL GAIN ADJUSTMENT
7.2 Auto tuning
7.2.1 Auto tuning mode
The servo amplifier has a real-time auto tuning function which estimates the machine characteristic (load
inertia moment ratio) in real time and automatically sets the optimum gains according to that value. This
function permits ease of gain adjustment of the servo amplifier.
(1) Auto tuning mode 1
The servo amplifier is factory-set to the auto tuning mode 1.
In this mode, the load inertia moment ratio of a machine is always estimated to set the optimum gains
automatically.

The auto tuning mode 1 may not be performed properly if the following
conditions are not satisfied.
Time to reach 2000r/min is the acceleration/deceleration time constant of 5s or
less.
Speed is 150r/min or higher.
The load to motor inertia moment ratio is 100 times or less.
The acceleration/deceleration torque is 10 or more of the rated torque.
Under operating conditions which will impose sudden disturbance torque during
acceleration/deceleration or on a machine which is extremely loose, auto tuning
may not function properly, either. In such cases, use the auto tuning mode 2 or
manual mode 1,2 to make gain adjustment.
(2) Auto tuning mode 2
Use the auto tuning mode 2 when proper gain adjustment cannot be made by auto tuning mode 1. Since
the load inertia moment ratio is not estimated in this mode, set the value of a correct load inertia moment
ratio (parameter No.34).
The following parameters are automatically adjusted in the auto tuning mode 2.

When a servo motor is accelerated/decelerated, the load inertia moment ratio estimation section always
estimates the load inertia moment ratio from the current and speed of the servo motor. The results of
estimation are written to parameter No.34 (the ratio of load inertia moment to servo motor). These results can
be confirmed on the status display screen of the MR Configurator (servo configuration software) section.
If the value of the load inertia moment ratio is already known or if estimation cannot be made properly, chose
the "auto tuning mode 2" (parameter No.2: 2
) to stop the estimation of the load inertia moment ratio
(Switch in above diagram turned off), and set the load inertia moment ratio (parameter No.34) manually.
From the preset load inertia moment ratio (parameter No.34) value and response level (The first digit of
parameter No.2), the optimum control gains are automatically set on the basis of the internal gain tale.
The auto tuning results are saved in the EEP-ROM of the servo amplifier every 60 minutes since power-on. At
power-on, auto tuning is performed with the value of each control gain saved in the EEP-ROM being used as
an initial value.
POINT
If sudden disturbance torque is imposed during operation, the estimation of the
inertia moment ratio may malfunction temporarily. In such a case, choose the
"auto tuning mode 2" (parameter No.2: 2
) and set the correct load inertia
moment ratio in parameter No.34.
When any of the auto tuning mode 1, auto tuning mode 2 and manual mode 1
settings is changed to the manual mode 2 setting, the current control gains and
load inertia moment ratio estimation value are saved in the EEP-ROM.

7.2.3 Adjustment procedure by auto tuning
Since auto tuning is made valid before shipment from the factory, simply running the servo motor automatically
sets the optimum gains that match the machine. Merely changing the response level setting value as required
completes the adjustment. The adjustment procedure is as follows.

7.2.4 Response level setting in auto tuning mode
Set the response (The first digit of parameter No.2) of the whole servo system. As the response level setting is
increased, the track ability and settling time for a command decreases, but a too high response level will
generate vibration. Hence, make setting until desired response is obtained within the vibration-free range.
If the response level setting cannot be increased up to the desired response because of machine resonance
beyond 100Hz, adaptive vibration suppression control (parameter No.60) or machine resonance suppression
filter (parameter No.58 59) may be used to suppress machine resonance. Suppressing machine resonance
may allow the response level setting to increase. Refer to section 8.2, 8.3 for adaptive vibration suppression
control and machine resonance suppression filter.

If you are not satisfied with the adjustment of auto tuning, you can make simple manual adjustment with three
parameters.
7.3.1 Manual Mode 1 basis
In this mode, setting the three gains of position control gain 1 (PG1), speed control gain 2 (VG2) and speed
integral compensation (VIC) automatically sets the other gains to the optimum values according to these gains.

Therefore, you can adjust the model adaptive control system in the same image as the general PI control

the speed gain to VG2 and the speed integral time constant to VIC. When making gain adjustment in this
mode, set the load inertia moment ratio (parameter No.34) correctly.
7.3.2 Adjustment by manual mode 1

POINT
The functions given in this chapter need not be used generally. Use them if you
are not satisfied with the machine status after making adjustment in the
methods in chapter 7.
If a mechanical system has a natural resonance level point, increasing the servo system response may cause
the mechanical system to produce resonance (vibration or unusual noise) at that resonance frequency.
Using the machine resonance suppression filter and adaptive vibration suppression control functions can
suppress the resonance of the mechanical system.

8. SPECIAL ADJUSTMENT FUNCTIONS
POINT
If the frequency of machine resonance is unknown, decrease the notch
frequency from higher to lower ones in order. The optimum notch frequency is
set at the point where vibration is minimal.
A deeper notch has a higher effect on machine resonance suppression but
increases a phase delay and may increase vibration.
The machine characteristic can be grasped beforehand by the machine
analyzer on the MR Configurator (servo configuration software). This allows the
required notch frequency and depth to be determined.
Resonance may occur if parameter No.58 59 is used to select a close notch
frequency and set a deep notch.
(b) Machine resonance suppression filter 2 (parameter No.59)
The setting method of machine resonance suppression filter 2 (parameter No.59) is the same as that of
machine resonance suppression filter 1 (parameter No.58). However, the machine resonance
suppression filter 2 can be set independently of whether adaptive vibration suppression control is valid
or invalid.
8.3 Adaptive vibration suppression control
(1) Function
Adaptive vibration suppression control is a function in which the servo amplifier detects machine resonance
and sets the filter characteristics automatically to suppress mechanical system vibration. Since the filter
characteristics (frequency, depth) are set automatically, you need not be conscious of the resonance
frequency of a mechanical system. Also, while adaptive vibration suppression control is valid, the servo
amplifier always detects machine resonance, and if the resonance frequency changes, it changes the filter
characteristics in response to that frequency.

POINT
The machine resonance frequency which adaptive vibration suppression
control can respond to is about 150 to 500Hz. Adaptive vibration suppression
control has no effect on the resonance frequency outside this range. Use the
machine resonance suppression filter for the machine resonance of such
frequency.
Adaptive vibration suppression control may provide no effect on a mechanical
system which has complex resonance characteristics or which has too large
resonance.
Under operating conditions in which sudden disturbance torque is imposed
during operation, the detection of the resonance frequency may malfunction
temporarily, causing machine vibration. In such a case, set adaptive vibration

8. SPECIAL ADJUSTMENT FUNCTIONS
(2) Parameters
Set the adaptive vibration suppression control (parameter No.60).
Parameter No.60
Adaptive vibration suppression control selection
Choosing "valid" or "held" in adaptive vibration suppression
control selection makes the machine resonance suppression
filter 1 (parameter No.58) invalid.
0: Invalid
1: Valid
Machine resonance frequency is always detected to
generate the filter in response to resonance, suppressing
machine vibration.
2: Held
Filter characteristics generated so far is held, and detection of
machine resonance is stopped.
Adaptive vibration suppression control sensitivity selection
Set the sensitivity of detecting machine resonance.
0: Normal
1: Large sensitivity
POINT
Adaptive vibration suppression control is factory-set to be invalid (parameter
No.60: 0000).
Setting the adaptive vibration suppression control sensitivity can change the
sensitivity of detecting machine resonance. Setting of "large sensitivity" detects
smaller machine resonance and generates a filter to suppress machine
vibration. However, since a phase delay will also increase, the response of the
servo system may not increase.
8.4 Low-pass filter
(1) Function
When a ball screw or the like is used, resonance of high frequency may occur as the response level of the
servo system is increased. To prevent this, the low-pass filter is factory-set to be valid for a torque
command. The filter frequency of this low-pass filter is automatically adjusted to the value in the following
expression.

POINT
In a mechanical system where rigidity is extremely high and resonance level is

8. SPECIAL ADJUSTMENT FUNCTIONS
8.5 Gain changing function
This function can change the gains. You can change between gains during rotation and gains during stop or
can use an external input signal to change gains during operation.
8.5.1 Applications
This function is used when.
(1) You want to increase the gains during servo lock but decrease the gains to reduce noise during rotation.
(2) You want to increase the gains during settling to shorten the stop settling time.
(3) You want to change the gains using an external input signal to ensure stability of the servo system since
the load inertia moment ratio varies greatly during a stop (e.g. a large load is mounted on a carrier).

9. INSPECTION
WARNING
Before starting maintenance and/or inspection, turn off the power and wait for 15
minutes or more until the charge lamp turns off. 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.
Due to risk of electric shock, only qualified personnel should attempt inspection.
For repair and parts replacement, please contact your local sales office.
CAUTION
Do not perform insulation resistance test on the servo amplifier as damage may
result.
Do not disassemble and/or repair the equipment on customer side.
(1) Inspection
It is recommended to make the following checks periodically.
(a) Check for loose terminal block screws. Retighten any loose screws.
(b) Check the cables and the like for scratches and cracks. Perform periodic inspection according to
operating conditions.
(c) Check the servo motor bearings, brake section, etc. for unusual noise.
(d) Check the cables and the like for scratches and cracks. Perform periodic inspection according to
operating conditions.
(e) Check the servo motor shaft and coupling for misalignment.
(2) Life
The following parts must be changed periodically as listed below. If any part is found faulty, it must be
changed immediately even when it has not yet reached the end of its life, which depends on the operating
method and environmental conditions. For parts replacement, please contact your local sales office.

depends on ambient temperature and operating conditions. The capacitor will reach the end of its life in
10 years of continuous operation in normal air-conditioned environment.
(b) Relays
Their contacts will wear due to switching currents and contact faults occur. Relays reach the end of their
life when the cumulative number of power-on and emergency stop times is 100,000, which depends on
the power supply capacity.

9. INSPECTION
(c) Servo amplifier cooling fan
The cooling fan bearings reach the end of their life in 10,000 to 30,000 hours. Normally, therefore, the
cooling fan must be changed in a few years of continuous operation as a guideline.
It must also be changed if unusual noise or vibration is found during inspection.
(d) Bearings
When the servo motor is run at rated speed under rated load, change the bearings in 20,000 to 30,000
hours as a guideline. This differs on the operating conditions. The bearings must also be changed if
unusual noise or vibration is found during inspection.
(e) Oil seal, V ring
Must be changed in 5,000 hours of operation at rated speed as a guideline. This differs on the operating
conditions. These parts must also be changed if oil leakage, etc. is found during inspection.

12. CHARACTERISTICS
12. CHARACTERISTICS
12.1 Overload protection characteristics
An electronic thermal relay is built in the servo amplifier to protect the servo motor, servo amplifier, and servo
motor power cable from overloads. Overload 1 (AL.50) occurs if overload operation performed is above the
electronic thermal relay protection curve shown in any of Figs 12.1, Overload 2 (AL.51) occurs if the maximum
current flew continuously for several seconds due to machine collision, etc. Use the equipment on the left-hand
side area of the continuous or broken line in the graph.
In a machine like the one for vertical lift application where unbalanced torque will be produced, it is
recommended to use the machine so that the unbalanced torque is 70% or less of the rated torque.

Note. If operation that generates torque more than 100% of the rating is performed with an abnormally high frequency in a servo motor stop
status (servo lock status) or in a 30r/min or less low-speed operation status, the servo amplifier may fail even when the electronic
thermal relay protection is not activated.
Fig 12.1 Electronic thermal relay protection characteristics
12.2 Power supply equipment capacity and generated loss
(1) Amount of heat generated by the servo amplifier
Table 12.1 indicates servo amplifiers' power supply capacities and losses generated under rated load. For
thermal design of an enclosure, use the values in Table 12.1 in consideration for the worst operating
conditions. The actual amount of generated heat will be intermediate between values at rated torque and
zero torque according to the duty used during operation. When the servo motor is run at less than the
maximum speed, the power supply capacity will be smaller than the value in the table, but the servo
amplifier's generated heat will not change.

12. CHARACTERISTICS
(2) Heat dissipation area for enclosed servo amplifier
The enclosed control box (hereafter called the control box) which will contain the servo amplifier should be
designed to ensure that its temperature rise is within 10 at the ambient temperature of 40 (104 ).
(With a 5 (41 ) safety margin, the system should operate within a maximum 55 (131 ) limit.) The
necessary enclosure heat dissipation area can be calculated by Equation 12.1.

where, A
: Heat dissipation area [m2]
P
: Loss generated in the control box [W]
T : Difference between internal and ambient temperatures [ ]
K

A
When calculating the heat dissipation area with Equation 12.1, assume that P is the sum of all losses
generated in the enclosure. Refer to Table 12.1 for heat generated by the servo amplifier. "A" indicates the
effective area for heat dissipation, but if the enclosure is directly installed on an insulated wall, that extra
amount must be added to the enclosure's surface area.
The required heat dissipation area will vary wit the conditions in the enclosure. If convection in the
enclosure is poor and heat builds up, effective heat dissipation will not be possible. Therefore, arrangement
of the equipment in the enclosure and the use of a cooling fan should be considered.
Table 12.1 lists the enclosure dissipation area for each servo amplifier when the servo amplifier is operated
at the ambient temperature of 40 (104 ) under rated load.

Fig. 12.2 Temperature distribution in enclosure
When air flows along the outer wall of the enclosure, effective heat exchange will be possible, because the
temperature slope inside and outside the enclosure will be steeper.

12. CHARACTERISTICS
12.3 Dynamic brake characteristics
POINT
Dynamic brake operates at occurrence of alarm, servo emergency stop
warning (AL.E6) and when power is turned off. Do not use dynamic brake to
stop in a normal operation as it is the function to stop in emergency.
Maximum usage time of dynamic brake for a machine operating under
recommended load inertia moment ratio is 1000 times while decelerating
from rated speed to a stop with frequency of once in 10 minutes.
Be sure to make emergency stop (EMG) valid after servo motor stops when
using emergency stop (EMG) frequently in other than emergency.
Fig. 12.3 shows the pattern in which the servo motor comes to a stop when the dynamic brake is operated.
Use Equation 12.2 to calculate an approximate coasting distance to a stop. The dynamic brake time constant
varies with the servo motor and machine operation speeds. (Refer to Fig. 12.4)

POINT
When using the MR-RB50, cooling by a cooling fan is required. Please obtain
a cooling fan at your discretion.
The regenerative option will cause a temperature rise of 100 relative to the ambient temperature. Fully
examine heat dissipation, installation position, used cables, etc. before installing the option. For wiring, use
flame-resistant cables and keep them clear of the regenerative option body. Always use twisted cables of
max. 5m length for connection with the servo amplifier.
Always remove the wiring from across P-D and fit the regenerative option across P-C.
The G3 and G4 terminals act as a thermal sensor. G3-G4 are disconnected when the regenerative option
overheats abnormally.

13.2.3 Power factor improving AC reactors
The power factor improving AC reactor FR-HAL increases the form factor of the servo amplifier's input current
to improve the power factor. It can reduce the power capacity. The input power factor is improved to be about
88 .
When using the power factor improving AC reactors FR-HAL for two or more servo amplifiers, be sure to
connect a power factor improving AC reactor FR-HAL to each servo amplifier. If using one power factor
improving AC reactor FR-HAL for multiple servo amplifiers, enough improvement effect of phase factor cannot
be obtained unless all servo amplifiers are operated.

13.2.6 Noise reduction techniques
Noises are classified into external noises which enter the servo amplifier to cause it to malfunction and those
radiated by the servo amplifier to cause peripheral devices to malfunction. Since the servo amplifier is an
electronic device which handles small signals, the following general noise reduction techniques are required.
Also, the servo amplifier can be a source of noise as its outputs are chopped by high carrier frequencies. If
peripheral devices malfunction due to noises produced by the servo amplifier, noise suppression measures
must be taken. The measures will vary slightly with the routes of noise transmission.
(1) Noise reduction techniques
(a) General reduction techniques
Avoid laying power lines (input and output cables) and signal cables side by side or do not bundle
them together. Separate power lines from signal cables.
Use shielded, twisted pair cables for connection with the encoder and for control signal transmission,
and connect the shield to the SD terminal.
Ground the servo amplifier, servo motor, etc. together at one point (refer to section 3.9).
(b) Reduction techniques for external noises that cause the servo amplifier to malfunction
If there are noise sources (such as a magnetic contactor, an electromagnetic brake, and many relays
which make a large amount of noise) near the servo amplifier and the servo amplifier may malfunction,
the following countermeasures are required.
Provide surge absorbers on the noise sources to suppress noises.
Attach data line filters to the signal cables.
Ground the shields of the encoder connecting cable and the control signal cables with cable clamp
fittings.
Although a surge absorber is built into the servo amplifier, to protect the servo amplifier and other
equipment against large exogenous noise and lightning surge, attaching a varistor to the power input
section of the equipment is recommended.
(c) Techniques for noises radiated by the servo amplifier that cause peripheral devices to malfunction
Noises produced by the servo amplifier are classified into those radiated from the cables connected to
the servo amplifier and its main circuits (input and output circuits), those induced electromagnetically or
statically by the signal cables of the peripheral devices located near the main circuit cables, and those
transmitted through the power supply cables.

Suppression techniques
1) 2) 3)
When measuring instruments, receivers, sensors, etc. which handle weak signals and may malfunction
due to noise and/or their signal cables are contained in a control box together with the servo amplifier or
run near the servo amplifier, such devices may malfunction due to noises transmitted through the air. The
following techniques are required.
(1) Provide maximum clearance between easily affected devices and the servo amplifier.
(2) Provide maximum clearance between easily affected signal cables and the I/O cables of the servo
amplifier.
(3) Avoid laying the power lines (Input cables of the servo amplifier) and signal cables side by side or
bundling them together.
(4) Insert a line noise filter to the I/O cables or a radio noise filter on the input line.
(5) Use shielded wires for signal and power cables or put cables in separate metal conduits.
4) 5) 6)
When the power lines and the signal cables are laid side by side or bundled together, magnetic induction
noise and static induction noise will be transmitted through the signal cables and malfunction may occur.
The following techniques are required.
(1) Provide maximum clearance between easily affected devices and the servo amplifier.
(2) Provide maximum clearance between easily affected signal cables and the I/O cables of the servo
amplifier.
(3) Avoid laying the power lines (Input cables of the servo amplifier) and signal cables side by side or
bundling them together.
(4) Use shielded wires for signal and power cables or put the cables in separate metal conduits.
7)
When the power supply of peripheral devices is connected to the power supply of the servo amplifier
system, noises produced by the servo amplifier may be transmitted back through the power supply cable
and the devices may malfunction. The following techniques are required.
(1) Insert the radio noise filter (FR-BIF) on the power cables (Input cables) of the servo amplifier.
(2) Insert the line noise filter (FR-BSF01) on the power cables of the servo amplifier.
8)
When the cables of peripheral devices are connected to the servo amplifier to make a closed loop circuit,
leakage current may flow to malfunction the peripheral devices. If so, malfunction may be prevented by
disconnecting the grounding cable of the peripheral device.
(2) Noise reduction products
(a) Data line filter
Noise can be prevented by installing a data line filter onto the encoder cable, etc.
For example, the ZCAT3035-1330 of TDK and the ESD-SR-250 of NEC Tokin make are available as
data line filters.
As a reference example, the impedance specifications of the ZCAT3035-1330 (TDK) are indicated

(c) Cable clamp fitting (AERSBAN -SET)
Generally, the earth of the shielded cable may only be connected to the connector's SD terminal.
However, the effect can be increased by directly connecting the cable to an earth plate as shown below.
Install the earth plate near the servo amplifier for the encoder cable. Peel part of the cable insulators to
expose the external conductor, and press that part against the earth plate with the cable clamp. If the
cable is thin, clamp several cables in a bunch.
The clamp comes as a set with the earth plate.

In this chapter, difference of the operation of MR-E- AG-QW003 from that of
MR-E- A-QW003 is described. For description not given in this chapter, refer
to chapters 1 through 13.
14.1 Functions and configuration
14.1.1 Introduction
The analog input MR-E- AG-QW003 Servo Amplifier is based on the MR-E- A-QW003 Servo Amplifier with
capability of speed control and torque control.
(1) Speed control mode
An external analog speed command (0 to 10VDC) or parameter-driven internal speed command (max. 7
speeds) is used to control the speed and direction of a servo motor smoothly.
There are also the acceleration/deceleration time constant setting in response to speed command, the
servo lock function at a stop time, and automatic offset adjustment function in response to external analog
speed command.
(2) Torque control mode
An external analog torque command (0 to 8VDC) or parameter-driven internal torque command is used
to control the torque output by the servo motor.
To prevent unexpected operation under no load, the speed limit function (external or internal setting) is also
available for application to tension control and the like.

Note 1. To prevent an electric shock, always connect the protective earth (PE) terminal (terminal marked ) of the servo amplifier to the
protective earth (PE) of the control box.
2. Connect the diode in the correct direction. If it is connected reversely, the servo amplifier will be faulty and will not output signals,
disabling the emergency stop and other protective circuits.
3. The emergency stop switch (normally closed contact) must be installed.
4. When starting operation, always connect the emergency stop (EMG) and forward rotation stroke end (LSP), reverse rotation stroke
end (LSN) with VIN. (Normally closed contacts)
5. Trouble (ALM) is connected with VIN in normal alarm-free condition. (Normally closed contacts)
6. When connecting the personal computer together with monitor outputs 1, 2, use the branch cable (MR-E3CBL15-P). (Refer to
section 13.1.3)
7. The pins with the same signal name are connected in the servo amplifier.
8. Use MRZJW3-SETUP 154E or 154C.
9. Externally supply 24VDC 10 , 200mA power for the interface. 200mA is a value applicable when all I/O signals are used.
Reducing the number of I/O points decreases the current capacity. Refer to the current necessary for the interface described in
section 3.6.2. Connect the external 24VDC power supply if the output signals are not used.

14.3 Startup
WARNING
Do not operate the switches with wet hands. You may get an electric shock.
CAUTION
Before starting operation, check the parameters. Some machines may perform
unexpected operation.
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,
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.
During operation, never touch the rotating parts of the servo motor. Doing so can
cause injury.
Perform pre-operation checks while referring to section 4.1. Connect the servo motor with a machine after
confirming that the servo motor operates properly alone.
Use parameter No.0 to choose the control mode used. After setting, this parameter is made valid by switching
power off, then on.

Configure up a circuit which will detect the trouble (ALM) signal and turn off
the servo-on (SON) signal at occurrence of an alarm.
When a fault occurs during operation, the corresponding alarm or warning is displayed. If any alarm or warning
has occurred, refer to section 10.2.2 or 10.2.3 and take the appropriate action. When an alarm occurs, the
current circuit between ALM and VIN opens.
Set "
1" in parameter No.49 to output the alarm code in ON/OFF status across the corresponding pin
and VIN. Warnings (AL.E0 to AL.E9) have no alarm codes. Any alarm code is output at occurrence of the
corresponding alarm. In the normal status, the signals available before alarm code setting (CN1-12: ZSP, CN111: RD, CN1-10: SA) are output.
After its cause has been removed, the alarm can be deactivated in any of the methods marked
