SAFETY PRECAUTIONS
(14)
Wiringwork is strictly allowed only for an engineer specializing electrical work.
(15)
A motor other than specified is not provided with a protection device. Protect a motor with an
overcurrent protection device, a ground-fault interrupter, overheating protection device, and emergency
stop device,etc.
(16)
When operating the driver after an earthquake, inspect installation conditions of the driver and the
motor and safety of the equipment to make sure that no fault exists.
(17)
After turning off the power, the inside circuit remains charged at a high voltage for a while. When
moving, wiring or inspection the equipment, completely shut off the power supply input outside the
driver and leave for 15 minutes or longer before working.
(18)
Install and mount the equipment securely to prevent personal injury caused by poor installation or
mounting on an earthquake.
(19)
Install an external emergency shutoff circuit to stop operation and interrupt power immediately upon
emergency. Emission of smoke or dust may occur due to a fault of a motor or a driver used in
combination.For example, if the system is energized with the regenerative control power transistor
shorted by failure,overheating of a regenerative resistor installed outside the driver may occur and it may
emit smoke and dust. If a regenerative resistor is connected outside a driver, provide a means of
detecting overheating such as a thermal protector to shut off power upon detecting abnormal heating.
(20)
Mount the motor, the driver and the peripheral devices on a noncombustible material such as metal.
(21)
Provide correct and secure wiring. Insecure wiring or incorrect wiring may cause runaway or burning of
a motor. During wiring work, avoid entry of conductive dust such as wire chippings in an driver.
(22)
Connect cables securely and provide secure insulation on current-carrying parts using insulation aterial.
(23)
Be sure to install a fuseless breaker in a power supply. Be sure to connect grounding terminals and
grounding wires. To prevent an electric shock and malfunction, type D grounding (grounding resistance
at 100
Ω or lower) or higher grade is recommended.
(24)
Tighten the screws on the terminal block and earth terminal securely at appropriate torque shown in the
specifications.
(25)
When building a system by using the safety feature, design it by fully understanding and being compliant
with the related safety standards and items described in our operation manual or technical reference.
(26)
Do not hold cables or motor shaft when carrying the equipment.
(27)
Do not adjust or change drive gains extremely, and do not make operations of the machine instable.
(28)
The equipment may suddenly restart after recovery from shutdown upon a power failure. Keep away
from the equipment. Specify settings of the equipment to secure safety for human against such restart
operations.
(29)
When the equipment is energized, keep away from the motor and mechanism driven by the motor in case
of malfunction.
(30)
Avoid a strong shock to the motor shaft.
(31)
Avoid a strong shock to the product.
(32)
Be sure not to use the electromagnetic contactor installed on the main power supply to start or stop the
motor.
(33)
Avoid frequent switching on and off the main power supply of the driver.
(34)
The built-in brake of the motor is used for holding only. Do not use the brake to stop (braking) for
securing safety of the equipment.
