 OUTLINE OF SELECTION OF SHAFTMOTOR
This sheet shows a general procedure for selection of appropriate model of shaftmotor.
User may check the validity of each selection by this sheet.
Actual temperature may vary much by the condition of refrigeration. selection would be influenced.
Please confirm on the shaftmotor in practical to verify the actual User should understand the actual condition from the
temperature is below the expected level. documents of manufacturer of the linear guide.
In case of using pre-pressure in the linear guide for high accuracy, Fill in the form to confirm whether any lack of the specification and
mechanical friction loss may be so big that the validity of the condition is remaining or not.

(1) Calculate the condition of load force
Estimate the external applying force by referring to the moving speed
illustration.
load force
Friction force of linear guide and resistence by
mass of load
deformation of cableveyer
are taken into account as an external force Fc. mass of coil resistense force
The mass of the coil(mover) Mc is assumed to be 1/10 guide
of the mass of load ML as initial value.

(2) Calculation of driving force

Calculate the necessary force F1 force during acceleration F1 = Fa+FL+Fr sum of Fa and load force
for each interval among the operation. F2 force during constant speed F2 = FL+Fr load force
Here, means friction coefficient of F3 force during deceleration F3 = Fd+FL+Fr sum of Fd and load force
linear guide. Fa acceleration force Fa = (ML+MC)XV/t1
G denotes gravitational acceleration. Fd deceleration force Fd = - (ML+MC)XV/t3
Fr resistence force during moving Fr = (ML+MC) G+FC

(3) selection of tentative shaftmotor model

Select tentatively a shaftmotor model, maximum force of which is larger than the maximum force among the calculated
necessary force. Keep 20-50% of margin.

(4) In the case of larger mass of coil Mc than the tentative value assumed in the step(1), go back to step(1)

(5) Confirmation on effective force

Calculate the effective force Feff from the necessary
force in each timing by the formula. {F12Xt1+F22Xt2+F32Xt3} Frated
Check whether the rated force of the shaftmotor Frated is Feff =
larger than the effective force even with a consideration (t1+t2+t3+t4+t5) SF
of some margin(safety ratio SF around 1.3 to 1.5).
(6) In the case of larger Feff than rated force of the coil, go gack to (3)

 INITIAL SETTING PROCEDURE OF THE DRIVER(For systems without hall sensors)

With the initial setting after shipping, driver may display 'E39-1' alarm at the first time it is turned on.
(In case of a system with hall sensor, this alarm doesn't occur.) This setting is for fail-safe purpose.
Before actual operation, user need to set appropriate values into parameters shown below.
* As for motor parameter (for the shaftmotor to be driven), set up by the set up software AHF is necessary.
In case the manufacturer set the motor parameter when shipping(charged), step7 is not necessary.
* General settings of other parameters than shown below should be also necessary. Consult to the manuals.

START Control power turn on 1 by this setting, E39 alarm may be resolved by the next control power turn on.
* In case of using hall sensors, leave FA-90 CnCt ,but it is necessary
to set other parameters appropriately according to the manual.

tip of sheet metal.

2. Automatic estimation function of magnetic pole detection

The driver can detect the position of the magnetic pole without hall sensor. For this function, searching procedure is necessary everytime
the driver is turned on, and is triggered by turning on the SON signal while RS signal has been turned on beforehand.While searching, the
shaftmotor moves as back and forth.
User must assure that no interferrence would happen during this movement.
Relationship of the movement and the parameter set in the driver is shown as below.

Fb-40
Fb-41 Fb-43 Fb-41 Twait

0 time[s]

Fb-41 Fb-43 Fb-41 Fb-42

-Fb-40

1 cycle

6 to 13 repetitions ( retry 4 times at worst)

By initial setting of the driver, each parameter is as below and the moving distance is about 1.6mm.
Speed Fb-40=80[mm/sec]
Acceleration time Fb-41=10[msec]
Constant speed time Fb-43=10[msec]
Halting time Fb-42=100[msec]

In some load condition, the detection fails with the initial parameter, and the driver displays E95 alarm.
Also, in case that smaller distance or smooth movement is necessary, change the parameter and try as below.
(1) In case of too small friction load, such as with air slide guide
1 Speed Fb-40 set up to larger value like "100" than initial setting "80"
*The distance becomes larger after commit 1
(2) In case of too large friction load, or smaller distance and smooth movement is required.
1 Speed Fb-40 be set up to smaller value like "50" than initial setting "80".
2 Acceleration time Fb-41 set up to larger value like "20" than initial setting "10"
3 Halting time Fb-43 set up to larger value like "300" than initial setting "100"
*The distance becomes larger after commit 2
*Testing is necessary for 1 and 2 because these changes make the estimation harder.
(3) In case of inaccurate setting of Fd-00(Mass of moving part) also leads to failure of this detection. Correct the setting in such case. ---See Page 11.

note)Consult to use in vertical movement

note)Consult if the operation does not work out or it is over permissible range.

 FOR CORRECT OPERATION

1 Notes on the safety about shaftmotor

(1) On the surface of the shaft of shaftmotors, the magnetic flux density is 0.5~0.7[T]( 5000~7000[G]).
Attractive force may work onto magnetic substances like iron.
Do not put any tool with magnetic substances near the shaft.
Do not assemble the shaftmotor without any protective materials covering the shaft.
Do not disassemble the shaft nor the coil unit of shaftmotor.
Damages will be caused if watches, products with precise mechanism, or floppy disks are put near the shaft.
(2) Do not transport, mount, connect, or inspect while an electrical power is applied to the shaftmotor.
Transportation, mounting, connection, or inspection must be performed by only specified trained personnel.
(3) Apply power after the shaft and the coil are correctly fixed to the mounting base.
(4) In case of disconnecting the feedback signal(linear sensor signal) during the operation, the shaftmotor will be out of control.
Be sure to make a perfect protection of wiring, add fail-safe mechanisms, and careful handling.
(5) Do not touch the moving part during operation.
(6) In heavy duty operation, the temperature of the surface of the coil may rise more than 70[˚C].
Do not touch the coil during operation, nor touch the coil while in rest but still before cooling.
(7) Use bolts with non-magnetized materials for fixing the shaft, coil, and mechanical parts near the shaft.
(8) Use tools with non-magnetized materials for fixing the shaft, coil, and mechanical parts near the shaft.
(9) When stocking the shaftmotor for a long time, cover the shaft with non-magnetized materials, thickness of more than 25mm,
and store in the dry place with moderate temperature(-5˚C~40˚C).
(10)Avoid from operation which exceeds the motor performance. Overheat, fire, damage, or degradation of performance may occur.

(1) Before use, be sure to read through the Instruction manual to insure proper use of the driver.
(2) Note that the driver requires electrical wiring; a specialist should carry out the wiring.
(3) The driver in this catalog is designed for general industrial applications. For special applications in fields such as aircraft,
outer space, nuclear power, electrical power, transport vehicles, clinics, and submarine relay equipment,please consult with us in advance.
(4) For application in a faclity where human life is involved or serious losses may occur, make sure to provide safty devices to avoid a serious accident.

*) The driver and the shaftmotor are intended to use with correct combination. If they are used with wrong combination,
there may be a chance of fire and damage.

Avoid installation in areas of high temperature, excessive humidity, or where moisture can easily collect, as well as
Installation location and areas that are dusty, subject to corrosive gasses, mist of liquid for grinding, or salt. Install the driver away from direct
operating environment sunlight in a well-ventilated room that is free of vibration. The driver can be operated in the ambient temperature range
from 0 to 55˚C.The shaftmotorr can be operated in the ambient temperature range from 0 to 40˚C.
(1) Be sure to connect main power wires with L1, L2, and L3 terminals (input) and motor wires to U, V, and W terminals
Wiring connections (output).(Incorrect connection will cause a breakdown.)
(2) Be sure to provide a grounding connection with the ground terminal ( ).
Run or stop of the motor must be done with IO signals through a control circuit terminal.
Run/Stop
Do not operate by installing a electromagnetic contactor (Mg) in the main circuit.
Speciality Be sure to confirm the load speciality before choosing the type of shaftmotor.
Install a circuit breaker on the main power input side to protect driver wiring and ensure personal safety.
Installing a circuit breaker Choose an inverter-compatible circuit breaker. The conventional type may malfunction due to harmonics from the driver.
For more information, consult the circuit breaker manufacturer.
Do not use a capacitor for power factor improvement between the driver and the motor.
Phase advance capacitor
High-frequency components of inverter output may overheat or damage the capacitor.
(1) High-frequency components are included in the input/output of the driver main circuit, and they may cause
High-Frequency Noise interference in a transmitter, radio, or sensor if used near the driver.
and Leakage Current The interference can be minimized by attaching noise filters (option) in the driver circuitry.
(2) The switching action of an driver causes an increase in leakage current. Be sure to ground the driver and the motor.
In the cases below involving a driver , a large peak current flows on the main power supply side,and is able to destroy the
converter module. Where such situations are foreseen or the connected equipment must be highly reliable,install an AC reactor
between the power supply and the driver. Also, where influence of indirect lightning strike is possible,install a lightning conductor.
(A) The unbalance factor of the power supply is 3% or higher. (Note)
(B) The power supply capacity is 10 times greater than the driver capacity (the power supply capacity is 500 kVA or more).
(C) Abrupt power supply changes are expected.
Examples: (1) Several drivers are interconnected with a short bus.
Installation of an AC (2) A thyristor converter and an driver are interconnected with a short bus.
reactors on the input side (3) An installed phase advance capacitor opens and closes.
In cases (A), (B) and (C), it is recommended to install an AC reactor on the main power supply side.
Note: Example calculation with VL1L2 = 205V, VL2L3 = 201V, VL3L1= 200V
Max. line voltage (min.) - Mean line voltage
Unbalance factor of voltage = X100

Because a smoothing capacitor deteriorates as it undergoes internal chemical reaction, it should normally be
replaced every five years. Be aware, however, that its life expectancy is considerably shoter   50
