SAFETY PRECAUTIONS
(14)
Wiring work should be done by an electrician's expert.
(15)
Protective devices are not attached to motors other than those specified. Please protect with overcurrent
protection device · earth leakage circuit breaker · temperature overheat prevention device · emergency stop
device etc.
(16)
When operating the servo driver after the earthquake, please check the installation condition of the servo
driver / motor and the safety of the machine beforehand and check that there is no abnormality before
driving.
(17)
After turning off the power supply, the internal circuit is charged with high voltage for a while. When
carrying out movement, wiring and inspection, completely shut off the power supply input outside the servo
driver, leave it for 15 minutes or more, then perform the operation.
(18)
When earthquakes occur, please ensure installation so that fire and personal injury will not occur due to
installation.
(19)
Install an emergency stop circuit externally so that operation can be immediately stopped and the power
can be shut off in case of emergency.There is a possibility of smoking and dust generation due to
malfunction of the motor and servo driver to be combined.As an example, if the regenerative control power
transistor with built-in servo driver is energized with a short-circuit fault, smoke generation and dust
generation due to overheating of the regenerative resistor installed outside the servo driver can occur.If a
regenerative resistor is connected to the outside of the servo driver, install overheat detecting means such
as a thermal protector to detect abnormal overheating and shut off the power supply.
(20)
Mount the motor, servo driver and peripheral devices on incombustible materials such as metal.
(21)
Wiring should be done correctly and reliably. Uncertain wiring and incorrect wiring may cause motor
malfunction or thermal damage. Also, during installation / wiring work, please make sure that conductors
such as wire scraps do not get inside the servo driver.
(22)
Be sure to connect the cables, and insulate the current-carrying parts securely with insulation.
(23)
When binding the wires and inserting them in a metal duct or the like for use, the permissible current of the
wire will decrease due to the temperature rise, causing thermal damage. Please consider the current
reduction coefficient and select the electric wire.
(24)
Be sure to install the wiring breaker (MCCB) on the power supply. Be sure to ground the earth terminal or
the ground wire.To prevent electric shock and malfunction, we recommend ground resistance 100 Ω or less.
(25)
Tighten the screws of the terminal block for connection and the grounding screw securely and securely with
the torque indicated in the specification sheet.
(26)
When constructing a system using the safety function, please design so as to understand and comply with related
safety standards and the description items of our manual or technical document.
(27)
Do not hold the cable or motor shaft during transportation.
(28)
In parameter adjustment of the servo driver, do not do extreme gain setting and action of changing the
setting value greatly at once, as it may lead to unexpected unstable operation.
(29)
Do not approach the machine because there is a possibility of a sudden restart after recovery at the time of
a power failure. Please set up the machine to ensure safety to people even after restarting.
(30)
Do not approach the motor and the machine driven by it during power-on in preparation for a malfunction
.
(31)
Do not apply strong impact to the motor shaft.
(32)
Do not operate or stop the motor with the magnetic contactor installed on the main power supply side.
(33)
Do not turn on / off the main power supply of the servo driver frequently.
(34)
When the brake is built in the motor, the built-in brake is for holding, so do not use it for a stop device
(braking) to ensure machine safety.
