WARNING
Do not touch the inside of the Servo Driver. Doing so may result in electric shock.
Always connect the frame ground terminals of the Servo Driver and the Servomotor
to a class-3 ground (to 100
Ω
or less). Not connecting to a class-3 ground may result
in electric shock.
Do not remove the front cover, terminal covers, cables, Parameter Units, or optional
items while the power is being supplied. Doing so may result in electric shock.
Operation, maintenance, or inspection must be performed by authorized personnel.
Not doing so may result in operation stoppage, burning of the product, electric
shock, or injury.
Wiring or inspection must be performed at least 1 minute after turning off the power
supply. Doing so may result in electric shock.
Do not damage, pull on, apply stress to, place heavy objects on, or pinch the cables.
Doing so may result in electric shock.
Do not touch the rotating parts of the Servomotor under operation. Doing so may
result in injury.
Do not modify the product. Doing so may result in injury or damage to the product.
Use the Servomotors and Servo Drivers in a specified combination. Not doing so
may result in fire or damage to the products.

Caution
Do not step on or place a heavy object on the product. Doing so may result in injury.
Do not cover the inlet or outlet ports and prevent any foreign objects from entering
the product. Doing so may result in fire.
Be sure to install the product in the correct direction. Not doing so may result in mal-
function.
Provide the specified clearances between the Servo Driver and the control panel or
with other devices. Not doing so may result in fire or malfunction.
Do not apply any strong impact. Doing so may result in malfunction.
Be sure to wire correctly and securely. Not doing so may result in motor runaway,
injury, or malfunction.
Be sure to firmly tighten the screws fixing the product, the terminal block, and cables.
Not doing so may result in malfunction.
Use crimp terminals for wiring. Do not connect bare stranded wires directly to the
terminal block. Doing so may result in fire.
Use the power supply voltages specified in this manual. Not doing so may result in
burning.
Take appropriate measures to ensure that the specified power with the rated voltage
is supplied. Be particularly careful in places where the power supply is unstable. Not
doing so may result in damage to the product.
Install external breakers and take other safety measures against short-circuiting in
