SAFETY PRECAUTIONS
(13)
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.
(14)
When operating the servo driver after an earthquake, inspect installation conditions of the servo driver
and the motor and safety of the equipment to make sure that no fault exists.
(15)
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 servo driver
and leave for 15 minutes or longer before working.
(16)
Install and mount the equipment securely to prevent personal injury caused by poor installation or
mounting on an earthquake.
(17)
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 servo 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 servo driver may occur and it may emit smoke
and dust. If a regenerative resistor is connected outside a servo driver, provide a means of detecting
overheating such as a thermal protector to shut off power upon detecting abnormal heating.
(18)
Mount the motor, the servo driver and the peripheral devices on a noncombustible material such as metal.
(19)
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 a servo driver.
(20)
Connect cables securely and provide secure insulation on current-carrying parts using insulation material.
(21)
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, Class D grounding (grounding resistance at 100
Ω
or
lower) or higher grade is recommended.
(22)
Do not adjust or change servo driver gains extremely, and do not make operations of the machine instable.
(23)
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.
(24)
When the equipment is energized, keep away from the motor and mechanism driven by the motor in case
of malfunction.
(25)
Avoid a strong shock to the product.
(26)
Be sure not to use the electromagnetic contactor installed on the main power supply to start or stop the
motor.
(27)
Avoid frequent switching on and off the main power supply of the servo driver.
