1. To prevent electric shock, note the following
Before wiring and inspections, 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, when confirming whether the charge lamp is off or
not, always confirm it from the front of the driver.
Ground the driver and servo motor securely.
Any person who is involved in wiring and inspection should be fully competent to do the work.
Do not attempt to wire the driver and servo motor until they have been installed. Otherwise, it may cause
an electric shock.
Do not operate switches with wet hands. Otherwise, it may cause an electric shock.
The cables should not be damaged, stressed, loaded, or pinched. Otherwise, it may cause an electric
shock.
During power-on or operation, do not open the front cover of the s driver. Otherwise, it may cause an
electric shock.
Do not operate the driver with the front cover removed. High-voltage terminals and charging area are
exposed and you may get an electric shock.
Except for wiring and periodic inspection, do not remove the front cover of the driver even if the power is
off. The driver is charged and you may get an electric shock.
To prevent an electric shock, always connect the protective earth (PE) terminal (marked ) of the driver
to the protective earth (PE) of the cabinet.
To avoid an electric shock, insulate the connections of the power supply terminals.
2. To prevent fire, note the following
Install the driver, servo motor, and regenerative resistor on incombustible material. Installing it directly or
close to combustibles will lead to a fire.
Always connect a magnetic contactor between the power supply and the main circuit power supply (L1,
L2, and L3) of the driver, in order to configure a circuit that shuts down the power supply on the side of
the driver’s power supply. If a magnetic contactor is not connected, continuous flow of a large current
may cause a fire when the driver malfunctions.
When using the regenerative resistor, switch power off with the alarm signal. Not doing so may cause a
fire when a regenerative transistor malfunctions or the like may overheat the regenerative resistor.
Provide adequate protection to prevent screws and other conductive matter, oil and other combustible
matter from entering the driver and servo motor.
Always connect a molded-case circuit breaker to the power supply of the driver.
3. To prevent injury, note the following
Only the voltage specified in the Instruction Manual should be applied to each terminal. Otherwise, a
burst, damage, etc. may occur.
Connect cables to the correct terminals. Otherwise, a burst, damage, etc. may occur.
Ensure that polarity (+/-) is correct. Otherwise, a burst, damage, etc. may occur.
The driver heat sink, regenerative resistor, servo motor, etc. may be hot while power is on or for some
time after power-off. Take safety measures, e.g. provide covers, to prevent accidental contact of hands
and parts (cables, etc.) with them.
