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 InstructionManual 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 hazardousconditions, 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 whatmust 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 InstructionManual, always keep it accessible to the operator.

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 thefront 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 anelectric 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 forwiring 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. Alwaysconnect 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 resistoris 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...
