dust, dirt, etc. (IP54). 

 

(4) Power supply 

(a) This servo amplifier can be used under the conditions of the overvolttage category   set forth 

in EN 60664-1, a reinforced insulating transformer is not required in the power input section. 

Unit shall be supplied from a three phase earthed neutral system. 

 

(b) For the interface power supply, use a 24VDC power supply with reinforced insulation on I/O 

terminals. 

 

(5) Grounding 

(a) To prevent an electric shock, the protective earth (PE) terminal (marked  ) of the servo 

amplifier must be connected to the protective earth (PE) of the control box. 

 

(b) Do not connect two ground cables to the same protective earth (PE) terminal. Always connect 

cables to the terminals one-to-one. 

PE terminals

PE terminals

 

(c) If a leakage current breaker is used to prevent an electric shock, the protective earth (PE) 

terminals of the servo amplifier must be connected to the corresponding earth terminals. 

 

(6) Wiring 

(a) The wires to be connected to the terminal block of the servo amplifier must have crimping 

terminals provided with insulating tubes to prevent contact with adjacent terminals.

(10)Overload Protection Characteristics 

An electronic thermal relay is built in the servo amplifier to protect the servo motor, servo 

amplifier and servo motor power line from overloads. The operation characteristics of the 

electronic thermal relay are shown below. It is recommended to use an unbalanced 

torque-generated machine, such as a vertical motion shaft, so that unbalanced torque is not more 

than 70  of the rated torque. 

Servo amplifier MR-J2S series have servo motor overload protection. (The motor full load current 

is 115  rated current.)

4.  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. 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. 

 

 

CAUTION

Do not test the servo amplifier with a megger (measure insulation resistance), 
or it may become faulty. 
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 servo motor bearings, brake section, etc. for unusual noise. 

 

(c) Check the cables and the like for scratches and cracks. Perform periodic inspection according 

to operating conditions. 

 

(d) 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 use in the atmosphere having much oil mist, dust, etc., clean and inspect every three months. 

For parts replacement, please contact your sales representative.

(a) Smoothing capacitor 

Affected by ripple currents, etc. and deteriorates in characteristic. The life of the capacitor 

greatly 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 

(Surrounding air temperature of 40  (104 ) or less.). 

 

(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 

 

(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 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) Servo motor 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) Servo motor 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. 

 

(f) Servo motor cooling fan 

The design life of the cooling fan is 20,000 hours. Change the cooling fan periodically.
