3. To prevent injury, note the following
CAUTION
Only the power/signal specified in the Instruction Manual should be applied to each terminal. Otherwise,
it may cause an electric shock, fire, injury, etc.
Connect cables to the correct terminals. Otherwise, a burst, damage, etc., may occur.
Ensure that polarity (+/-) is correct. Otherwise, a burst, damage, etc., may occur.
The servo amplifier heat sink, regenerative resistor, servo motor, etc., may be hot while the power is on
and for some time after power-off. Take safety measures such as providing covers to avoid accidentally
touching them by hands and parts such as cables.
4. Additional instructions
The following instructions should also be fully noted. Incorrect handling may cause a malfunction, injury,
electric shock, fire, etc.
(1) Transportation and installation
CAUTION
Transport the products correctly according to their mass.
Stacking in excess of the specified number of product packages is not allowed.
Do not hold the front cover, cables, or connectors when carrying the servo amplifier. Otherwise, it may
drop.
Install the servo amplifier and the servo motor in a load-bearing place in accordance with the Instruction
Manual.
Do not get on or put heavy load on the product. Otherwise, it may cause injury.
The equipment must be installed in the specified direction.
Maintain specified clearances between the servo amplifier and the inner surfaces of a control cabinet or
other equipment.
Do not install or operate the servo amplifier and servo motor which have been damaged or have any
parts missing.
Do not block the intake and exhaust areas of the servo amplifier. Otherwise, it may cause a malfunction.
Do not drop or apply heavy impact on the servo amplifiers and the servo motors. Otherwise, it may cause
injury, malfunction, etc.
Do not strike the connector. Otherwise, it may cause a connection failure, malfunction, etc.
When you keep or use the equipment, please fulfill the following environment.

CAUTION
Fumigants that are used to disinfect and protect wooden packaging from insects contain halogens (such
as fluorine, chlorine, bromine, and iodine) cause damage if they enter our products. Please take
necessary precautions to ensure that remaining materials from fumigant do not enter our products, or
treat packaging with methods other than fumigation, such as heat treatment. Additionally, disinfect and
protect wood from insects before packing the products.
To prevent a fire or injury in case of an earthquake or other natural disasters, securely install, mount, and
wire the servo motor in accordance with the Instruction Manual.
(2) Wiring
CAUTION
Wire the equipment correctly and securely. Otherwise, the servo motor may operate unexpectedly.
Make sure to connect the cables and connectors by using the fixing screws and the locking mechanism.
Otherwise, the cables and connectors may be disconnected during operation.
Do not install a power capacitor, surge killer, or radio noise filter (optional FR-BIF(-H)) on the servo
amplifier output side.
To avoid a malfunction, connect the wires to the correct phase terminals (U/V/W) of the servo amplifier
and servo motor.
Connect the servo amplifier power output (U/V/W) to the servo motor power input (U/V/W) directly. Do
not connect a magnetic contactor and others between them. Otherwise, it may cause a malfunction.

The connection diagrams in this Instruction Manual are shown for sink interfaces, unless stated
otherwise.
The surge absorbing diode installed to the DC relay for control output should be fitted in the specified
direction. Otherwise, the converter unit and the drive unit will malfunction and will not output signals,
disabling the emergency stop and other protective circuits.

When the wires are not tightened enough to the terminal block, the wires or terminal block may generate
heat because of the poor contact. Be sure to tighten the wires with specified torque.
Connecting a servo motor of the wrong axis to U, V, W, or CN2 of the servo amplifier may cause a
malfunction.
Configure a circuit to turn off EM2 or EM1 when the main circuit power supply is turned off to prevent an
unexpected restart of the servo amplifier.
To prevent malfunction, avoid bundling power lines (input/output) and signal cables together or running
them in parallel to each other. Separate the power lines from the signal cables.

(3) Test run and adjustment
CAUTION
When executing a test run, follow the notice and procedures in this instruction manual. Otherwise, it may
cause a malfunction, damage to the machine, or injury.
Before operation, check and adjust the parameter settings. Improper settings may cause some machines
to operate unexpectedly.
Never make a drastic adjustment or change to the parameter values as doing so will make the operation
unstable.
Do not get close to moving parts during the servo-on status.
(4) Usage
CAUTION
Provide an external emergency stop circuit to stop the operation and shut the power off immediately.
For equipment in which the moving part of the machine may collide against the load side, install a limit
switch or stopper to the end of the moving part. The machine may be damaged due to a collision.
Do not disassemble, repair, or modify the product. Otherwise, it may cause an electric shock, fire, injury,
etc. Disassembled, repaired, and/or modified products are not covered under warranty.
Before resetting an alarm, make sure that the run signal of the servo amplifier is off in order to prevent a
sudden restart. Otherwise, it may cause an accident.
Use a noise filter, etc., to minimize the influence of electromagnetic interference. Electromagnetic
interference may affect the electronic equipment used near the servo amplifier.
Do not burn or destroy the servo amplifier. Doing so may generate a toxic gas.
Use the servo amplifier with the specified servo motor.
Wire options and peripheral equipment, etc. correctly in the specified combination. Otherwise, it may
cause an electric shock, fire, injury, etc.
The electromagnetic brake on the servo motor is designed to hold the motor shaft and should not be
used for ordinary braking.
For such reasons as incorrect wiring, service life, and mechanical structure (e.g. where a ball screw and
the servo motor are coupled via a timing belt), the electromagnetic brake may not hold the motor shaft.
To ensure safety, install a stopper on the machine side.
If the dynamic brake is activated at power-off, alarm occurrence, etc., do not rotate the servo motor by an
external force. Otherwise, it may cause a malfunction of the dynamic brake or a fire.
