Safety Instructions

(Always read these instructions before using the equipment.)

Do not attempt to install, operate, maintain or inspect the servo amplifier and servo motor until you have read through this Instruction Manual, Installation guide, Servo motor Instruction Manual and appended documents carefully and can use the equipment correctly. Do not use the servo amplifier and servo motor until you have a full knowledge of the equipment, safety information and instructions.

In this Instruction Manual, the safety instruction levels are classified into "WARNING" and "CAUTION".

WARNING

CAUTION

Indicates that incorrect handling may cause hazardous conditions, resulting in death or severe injury.

Indicates that incorrect handling may cause hazardous conditions, resulting in medium or slight injury to personnel or may cause physical damage.

Note that the CAUTION level may lead to a serious consequence according to conditions. Please follow the instructions of both levels because they are important to personnel safety.

What must not be done and what must be done are indicated by the following diagrammatic symbols:

: Indicates what must not be done. For example, "No Fire" is indicated by

: Indicates what must be done. For example, grounding is indicated by .

.

In this Instruction Manual, instructions at a lower level than the above, instructions for other functions, and so on are classified into "POINT".

After reading this Instruction Manual, always keep it accessible to the operator.

A - 1

1. To prevent electric shock, note the following:

WARNING

Before wiring or inspection, switch power off and wait for more than 15 minutes. Then, confirm the voltage is safe with voltage tester. Otherwise, you may get an electric shock.

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

Do not install the servo amplifier, servo motor and regenerative brake resistor on or near combustibles.

Otherwise a fire may cause.

When the servo amplifier has become faulty, switch off the main servo amplifier power side. Continuous flow of a large current may cause a fire.

When a regenerative brake resistor is used, use an alarm signal to switch main power off. Otherwise, a regenerative brake transistor fault or the like may overheat the regenerative brake 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 brake 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.

4. Additional instructions

The following instructions should also be fully noted. Incorrect handling may cause a fault, injury, electric shock, etc.

(1) Transportation and installation

CAUTION

Transport the products correctly according to their weights.

Stacking in excess of the specified number of products is not allowed.

Do not carry the servo motor by the cables, shaft or encoder.

Do not hold the front cover to transport the servo amplifier. The servo amplifier may drop.

Install the servo amplifier in a load-bearing place in accordance with the Instruction Manual.

Do not climb or stand on servo equipment. Do not put heavy objects on equipment.

The servo amplifier and servo motor must be installed in the specified direction.

Leave specified clearances between the servo amplifier and control enclosure walls or other equipment.

Do not install or operate the servo amplifier and servo motor which has been damaged or has any parts missing.

Provide adequate protection to prevent screws and other conductive matter, oil and other combustible matter from entering the servo amplifier and servo motor.

Do not drop or strike servo amplifier or servo motor. Isolate from all impact loads.

When you keep or use it, please fulfill the following environmental conditions.

A - 3

CAUTION

Securely attach the servo motor to the machine. If attach insecurely, the servo motor may come off during operation.

The servo motor with reduction gear must be installed in the specified direction to prevent oil leakage.

Take safety measures, e.g. provide covers, to prevent accidental access to the rotating parts of the servo motor during operation.

Never hit the servo motor or shaft, especially when coupling the servo motor to the machine. The encoder may become faulty.

Do not subject the servo motor shaft to more than the permissible load. Otherwise, the shaft may break.

When the equipment has been stored for an extended period of time, consult Mitsubishi.

(2) Wiring

CAUTION

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

Do not install a power capacitor, surge absorber or radio noise filter (FR-BIF option) between the servo motor and servo amplifier.

Connect the output terminals (U, V, W) correctly. Otherwise, the servo motor will operate improperly.

Connect the servo motor power terminal (U, V, W) to the servo motor power input terminal (U, V, W) directly. Do not let a magnetic contactor, etc. intervene.

(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 ballscrew 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).

Circuit must be opened during forced stop (EM1).

When any alarm has occurred, eliminate its cause, ensure safety, and deactivate the alarm before restarting operation.

When power is restored after an instantaneous power failure, keep away from the machine because the machine may be restarted suddenly (design the machine so that it is secured against hazard if restarted).
