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, when confirming whether the charge lamp is off or not, always
confirm it from the front of the servo amplifier.
●
Ground the servo amplifier 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 servo amplifier 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 servo amplifier. Otherwise, it may cause
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 and periodic inspection, do not remove the front cover of the servo amplifier even if the
power is off. The servo amplifier is charged and you may get an electric shock.
●
To prevent electric shock, always connect the protective earth (PE) terminal (marked ) of the servo
amplifier to the protective earth (PE) of the cabinet.
●
When using a residual current device (RCD), select the type B.
●
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 power supply and the main circuit power supply
(L1/L2/L3) of the servo amplifier in order to configure a power supply shut-off 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 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 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 cables to the correct terminals. Otherwise, a burst, damage, etc. may occur.
●
Ensure that the polarity (+/-) is correct. Otherwise, a burst, damage, etc. may occur.
●
The servo amplifier 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 avoid accidentally touching the
parts (cables, etc.) by hand. )
