(3) When using A/B/Z-phase differential output linear encoder with MR-J4-_B_-RJ

The configuration diagram is an example of MR-J4-20B-RJ. When using the other servo amplifiers, the

configuration will be the same as rotary servo motors except for connections of linear servo motors and

linear encoders. Refer to section 1.8 depending on servo amplifiers you use.

1-phase 200 V AC to 240 V AC power supply may be used with the servo amplifier of MR-J4-200B-RJ or less. For 1-phase

200 V AC to 240 V AC, connect the power supply to L1 and L3. Leave L2 open. For the power supply specifications, refer to

section 1.3.

3. Depending on the main circuit voltage and operation pattern, bus voltage decreases, and that may cause the forced stop

deceleration to shift to the dynamic brake deceleration. When dynamic brake deceleration is not required, slow the time to turn

off the ma

5. Connect the thermistor to CN2 of servo amplifier and connect the encoder cable to CN2L correctly. Incorrect setting will trigger

14.2 Signals and wiring

WARNING

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. 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,

when confirming whether the charge lamp is off or not, always confirm it from the

front of the servo amplifier.

Ground the servo amplifier and the linear servo motor securely.

Do not attempt to wire the servo amplifier and the linear servo motor until they

have been installed. Otherwise, it may cause an electric shock.

The cables should not be damaged, stressed, loaded, or pinched. Otherwise, it

may cause an electric shock.

To avoid an electric shock, insulate the connections of the power supply terminals.

CAUTION

Wire the equipment correctly and securely. Otherwise, the linear servo motor may

operate unexpectedly, resulting in injury.

Connect cables to the correct terminals. Otherwise, a burst, damage, etc. may

occur.

Ensure that polarity (+/-) is correct. Otherwise, a burst, damage, etc. may occur.

The surge absorbing diode installed to the DC relay for control output should be

fitted in the specified direction. Otherwise, the emergency stop and other

protective circuits may not operate.

Use a noise filter, etc. to minimize the influence of electromagnetic interference.

Electromagnetic interference may be given to the electronic equipment used near

the servo amplifier.

Do not install a power capacitor, surge killer or radio noise filter (optional FR-BIF(-

H)) with the power wire 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.

Connect the servo amplifier power output (U/V/W) to the linear servo motor power

input (U/V/W) directly. Do not let a magnetic contactor, etc. intervene. Otherwise,

it may cause a malfunction.

CAUTION

Before wiring, switch operation, etc., eliminate static electricity. Otherwise, it may

cause a malfunction.

Connecting a linear servo motor for different axis to the U, V, W, or CN2 may

cause a malfunction.

Do not modify the equipment.

The cables such as power wires deriving from the primary side cannot stand the

long-term bending action. Avoid the bending action by fixing the cables to the

moving part, etc. Also, use the cable that stands the long-term bending action for

the wiring to the servo amplifier.
