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

 

 

 

 

CAUTION

 

Except for wiring or periodic inspection, do not remove the front cover even if the power is off. The 
servo amplifier is charged and you may get an electric shock. 
 To avoid an electric shock, insulate the connections of the power supply terminals. 

 

 
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 between the main circuit power supply and L

1

, L

2

, and L

3

 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 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. 
Provide adequate protection to prevent screws and other conductive matter, oil and other combustible 
matter from entering the servo amplifier and servo motor. 
Always connect a molded-case circuit breaker to the power supply of the servo amplifier. 

 

 

3. To prevent injury, note the following 

 

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. 

 

 

4. Additional instructions 

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