1. To prevent electric shock, note the following:
WARNING
Before wiring 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.
Connect the servo amplifier and servo motor to ground.
Any person who is involved in wiring and inspection should be fully competent to do the work.
Do not attempt to wire the servo amplifier and servo motor until they have been installed. Otherwise, you may get an electric shock.
Operate the switches with dry hand to prevent an electric shock.
The cables should not be damaged, stressed, loaded, or pinched. Otherwise, you may get an electric shock.
During power-on or operation, do not open the front cover of the servo amplifier. You may get an electric shock.
Do not operate the servo amplifier with the front cover removed. High-voltage terminals and charging area are exposed and you may get an electric shock.
Except for wiring or periodic inspection, do not remove the front cover even of the servo amplifier if the power is off. The servo amplifier is charged and you may get an electric shock.
2. To prevent fire, note the following:
CAUTION
Install the servo amplifier, servo motor and regenerative resistor on incombustible material. Installing them directly or close to combustibles will lead to a fire.
Always connect a magnetic contactor (MC) between the main circuit power supply and L1, L2, and L3 of the servo amplifier, and configure the wiring to be able to shut down the power supply on the side of the servo amplifier’s power supply. If a magnetic contactor (MC) is not connected, continuous flow of a large current may cause a fire when the servo amplifier malfunctions.
When a regenerative resistor is used, use an alarm signal to switch main power off. Otherwise, a regenerative transistor fault or the like may overheat the regenerative resistor, causing a fire.
3. To prevent injury, note the follow
CAUTION
Only the voltage specified in the Instruction Manual should be applied to each terminal. Otherwise, a burst, damage, etc. may occur.
Connect the terminals correctly to prevent a burst, damage, etc.
Ensure that polarity (
, ) is correct. Otherwise, a burst, damage, etc. may occur.
Take safety measures, e.g. provide covers, to prevent accidental contact of hands and parts (cables, etc.) with the servo amplifier heat sink, regenerative resistor, servo motor, etc. since they may be hot while power is on or for some time after power-off. Their temperatures may be high and you may get burnt or a parts may damaged.
During operation, never touch the rotating parts of the servo motor. Doing so can cause injury.

(3) Test run adjustment
CAUTION
Before operation, check the parameter settings. Improper settings may cause some machines to perform unexpected operation.
The parameter settings must not be changed excessively. Operation will be insatiable.
(4) Usage
CAUTION
Provide a forced stop circuit to ensure that operation can be stopped and power switched off immediately. Any person who is involved in disassembly and repair should be fully competent to do the work.
Before resetting an alarm, make sure that the run signal of the servo amplifier is off to prevent an accident. A sudden restart is made if an alarm is reset with the run signal on.
Do not modify the equipment.
Use a noise filter, etc. to minimize the influence of electromagnetic interference, which may be caused by electronic equipment used near the servo amplifier.
Burning or breaking a servo amplifier may cause a toxic gas. Do not burn or break a servo amplifier. Use the servo amplifier with the specified servo motor.
The electromagnetic brake on the servo motor is designed to hold the motor shaft and should not be used for ordinary braking.
For such reasons as service life and mechanical structure (e.g. where a ball screw and the servo motor are coupled via a timing belt), the electromagnetic brake may not hold the motor shaft. To ensure safety, install a stopper on the machine side.
(5) Corrective actions
CAUTION
When it is assumed that a hazardous condition may take place at the occur due to a power failure or a product fault, use a servo motor with electromagnetic brake or an external brake mechanism for the purpose of prevention.
Configure the electromagnetic brake circuit so that it is activated not only by the interface unit signals but also by a forced stop (EM1).
Contacts must be open when servo-off, when an alarm occurrence and when an electromagnetic brake interlock (MBR).

COMPLIANCE WITH EC DIRECTIVES
1. WHAT ARE EC DIRECTIVES?
The EC directives were issued to standardize the regulations of the EU countries and ensure smooth distribution of safety-guaranteed products. In the EU countries, the machinery directive (effective in January, 1995), EMC directive (effective in January, 1996) and low voltage directive (effective in January, 1997) of the EC directives require that products to be sold should meet their fundamental safety requirements and carry the CE marks (CE marking). CE marking applies to machines and equipment into which servo amplifiers have been installed.
(1)EMC directive
The EMC directive applies not to the servo units alone but to servo-incorporated machines and equipment. This requires the EMC filters to be used with the servo-incorporated machines and equipment to comply with the EMC directive. For specific EMC directive conforming methods, refer to the EMC Installation Guidelines (IB(NA)67310).
(2)Low voltage directive
The low voltage directive applies also to servo units alone. Hence, they are designed to comply with the low voltage directive.
This servo is certified by TUV, third-party assessment organization, to comply with the low voltage directive.
(3)Machine directive
Not being machines, the servo amplifiers need not comply with this directive.
2. PRECAUTIONS FOR COMPLIANCE
(1)Servo amplifiers and servo motors used
Use the servo amplifiers and servo motors which comply with the standard model.

1.FUNCTIONS AND CONFIGURATION
1.FUNCTIONS AND CONFIGURATION
1.1 Introduction
The Mitsubishi MELSERVO-J2-Super series general-purpose AC servo is based on the MELSERVO-J2 series and has further higher performance and higher functions.
It is connected with a servo system controller or similar device via a serial bus (SSCNET) and the servo amplifier reads position data directly to perform operation.
Data from a command unit controls the speed and rotation direction of the servo motor and executes precision positioning.
A torque limit is imposed on the servo amplifier by the clamp circuit to protect the power transistor in the main circuit from overcurrent due to sudden acceleration/deceleration or overload. The torque limit value can be changed to any value with an external analog input or the parameter.
As this new series has the RS-232C serial communication function, a MR Configurator (servo configuration software)-installed personal computer or the like can be used to perform parameter setting, test operation, status display monitoring, gain adjustment, etc.
With real-time auto tuning, you can automatically adjust the servo gains according to the machine.
The MELSERVO-J2-Super series servo motor is equipped with an absolute position encoder which has the resolution of 131072 pulses/rev to ensure more accurate control as compared to the MELSERVO-J2 series. Simply adding a battery to the servo amplifier makes up an absolute position detection system. This makes home position return unnecessary at power-on or alarm occurrence by setting a home position once.
