(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.
