Safety Precautions
(16)
Before operating the servo driver following an earthquake, ensure that the servo driver and motor are properly
installed and that the machine is safe.
(17)
After the power supply is switched off, the internal circuit will be charged at high voltage for a period of time.
When relocating, wiring, or inspecting the driver, ensure that the power supply input is completely disconnected
on the outside of the servo driver and wait at least 15 minutes before carrying out any work.
(18)
Install and set up the product so that it does not cause fire or personal injury in the event of an earthquake.
(19)
Install an external emergency stop circuit must be installed to enable the power supply to be immediately
disconnected in the event of an emergency. Failure of the combined motor and servo driver may result in smoke
and dust being emitted. For example, if an electric current is passed through the regenerative control power
transistor built into the servo driver following a short-circuit fault, the regenerative resistor installed outside the
servo driver may overheat, leading to smoke and dust being emitted.
If a regenerative resistor is connected to the outside of the servo driver, it must be installed so that the thermal
protector or other overheating detection devices can detect abnormal overheating and to enable the power
supply to be disconnected
(20)
Install the motor, servo driver, and peripheral devices to nonflammable materials such as metal.
(21)
Ensure that the product is wired correctly and securely. Insecure or incorrect wiring may cause the motor to
malfunction or lead to thermal damage. Also, do not allow any conductive materials such as wire debris to enter
the servo driver during installation and wiring.
(22)
Ensure that the cables are securely connected and that energized parts are insulated.
(23)
Binding and inserting wires into a metal duct will cause the temperature to increase, which will result in reduced
wire current capacity and possibly lead to thermal damage. Please consider the current reduction coefficient
before deciding on how to wire the product.
(24)
Make sure to install a molded case circuit breaker (MCCB) to the power supply. Also, make sure to ground the
ground terminal or ground wire.
D-type grounding or higher (ground resistance less than 100
Ω
) is recommended in order to prevent electric
shocks and malfunctions
(25)
Securely tighten the screws for connecting the terminal block, as well as the grounding screw, using the torque
indicated in the specification sheet.
(26)
When constructing a system using safety features, make sure you understand and comply with the relevant
safety standards as well as the information in our user manuals or technical reference documents.
(27)
When transporting the product, do not hold it by the cable or motor shaft.
(28)
When adjusting the parameters of the servo driver, do not set the gain too high or make extreme modifications
to settings simultaneously, as doing so may result in unstable operation.
(29)
Following a power outage, do not get close to the machine once power is restored, as it may restart suddenly.
Settings must be made to ensure personal safety even in event the machine restarts suddenly.
(30)
Do not approach the motor or the machine when it is running during power-up to ensure safety in the event of
an unexpected malfunction.
(31)
Do not subject the motor shaft to strong shock.
(32)
Do not use the electromagnetic contactor installed on the main power supply side to start or stop the motor.
(33)
Do not turn the servo driver main power supply on and off more frequently than necessary.
(34)
If the motor has a built-in brake, it is for maintenance purposes and should not be used as a stopping (braking)
device in order to ensure machine safety.
(35)
Do not drop or tip over the product during transportation or installation.
