DANGER
Attention on safety
Please read this user’s manual carefully before using and use rightly.
The purpose of this attention is to protect users or others from the injure, damage or loss of
property in advance and use this product rightly and safely.
This danger shows the possibility that the user may die or get serious
injures by fire or electrical shock and the contents which are high
emergency of caution when danger is occurred if this warning is neglected
and operated.
This warning shows the possibility that the user may die or get serious
injures, fire or electrical shock if this warning is neglected and operated.
This caution shows the possibility that the user may be injured by electrical
shock or the contents which expect to issue physical damage if this caution
is neglected and operated.
● Do not use the unit broken or disassembled.It may become the cause of fire or
electric shock.
● Do not repair or reconstruct by no means because repair and reconstruction may issue a
danger which causes serious accident.
●Do not use the unit near by corrosive gas, inflammable gas, explosive atmosphere,
watery or oily place or inflammables. It may cause fire, electric shock or injury.
●Only person who has special knowledge is requested to work for setting, wiring,
operation, inspection, maintenance and so on. There is a reason of electric shock
and injury.
●Keep rated input power voltage range surely. There is a reason of fire or damage.
●Make sure the wiring according to wiring example.There is areason of fire or
damage.

injure.
●Fix the driver tightly when installing. It may cause injury.
●Do not touch the terminal base during power on by no means because some terminals have
high voltage. There is a reason of fire and electric shock.
●Do not touch the driver during operation and for the time being after stop. Because the
surface of driver is hot depending of operating condition, it may cause injury.

●MYCOM is, in no way, responsible for any damages or malfunctions that are caused by
user’s repair or modifications on this driver. If the user performed these initiations and the
driver does not work satisfactory, a warranty will not be provided.
●When giving up the use of the driver, dispose it according to an appropriate regulation on
the industrial waste.

4-2-1. Power indicator LED (POWER)
This rights on during power on.
4-2-2. Overheat indicator LED (HEAT)
This rights on when the temperature of internal heat-sink rises and becomes overheat
condition. Then a signal is outputted to the HEAT output of CN.
4-2-3. Excitation timing ZERO output terminal (MONI)
Asignal is outputted from MONI terminal of CN when output excitation pattern is
excitation timing origin.
4-2-4. Motor current shutoff signal (CO)
Motor winding current turn-on/off signal. When this input terminal of CN is kept ON,
the motor shaft can be rotated externally.
H level : Motor winding current-off
L level : Motor winding current-on
4-2-5. Automatic current-off function (A.CO)
This function is to cut automatically all current to motor when the temperature in the
driver rises and becomes overheat condition.
4-2-6. (Automatic current reduction function (A.CD)
200ms after the motor stops, the motor winding current is reduced until about 50% of
normal driving to minimize motor heating.
In case of current down status, certain position gap issues without relation
to resolution by affecting motor characteristic to be used.

6-1. Wiring for motor lines and power lines
・When wiring, surely wire the protect earth line at first.
・Install noise filter at power input where noise sources exist near the driver.
・This driver has fuse inside, but use no-fuse-breaker of “3A current capacity”or circuit
protector of the capacity of below table for safety.
6-2. Wiring of motor line
・The radiant noise can be depressed by shield cable equal to or bigger than AWG22(0.5mm2)
in case that redundant radiant noise is trouble.
・In case that the motor wiring is longer, please use the shield cable equal to or bigger than
AWG22(0.5mm2)

6-4. Tightening torque for terminal block
Do not add vertical force against screw when connecting with terminal.
Please tighten the screw within torque of 0.392〜0.686N・m(4〜7Kgf・cm) at stopping.
6-5. Install condition
・Do not use driver outside of control box. This unit is designed for the following condition.
Over voltage category: Category II, Material group III
Pollution degree: Class 2
Protection structure: IP20(IMS20-210), IP00(IMS20-210L)
Protection against electric shock: Class I component
・Fix driver on heat conductive metal plate tightly.
・Put 3cm or more space between each driver and fix the drivers when multiple drivers
are arranged.
・Pay attention not to close the side slits of driver.
・Confirm that the driver environmental temperature is less than 40℃when overheat
lamp lights.
・Use screws of “thickness of installing place plus 3 to 5mm”if the driver is installed
directly by screws not by accessory bracket.
・Because this unit uses high speed photo coupler for the part of input pulse, use the
shield line for signal cable.
・Put this unit vertically because this unit radiates by natural convection. (Refer the
below figure)
There is a possibility that driver chassis temperature exceeds 60℃depending on load
condition or other environmental condition.
