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.

(5) Corrective actions
CAUTION
Ensure safety by confirming the power off, etc. before performing corrective actions. Otherwise, it may
cause an accident.
If it is assumed that a power failure, machine stoppage, or product malfunction may result in a hazardous
situation, use a servo motor with an electromagnetic brake or provide an external brake system for
holding purpose to prevent such hazard.
Configure an electromagnetic brake circuit which is interlocked with an external emergency stop switch.

Contacts must be opened with
the emergency stop switch.
Contacts must be opened when ALM
(Malfunction) or MBR (Electromagnetic
brake interlock) turns off.
24 V DC
Failure of MBR (Electromagnetic brake interlock) or ALM (Malfunction) may cause brake malfunction.
When an alarm occurs, eliminate its cause, ensure safety, and deactivate the alarm to restart operation.
If the molded-case circuit breaker or fuse is activated, be sure to remove the cause and secure safety
before switching the power on. If necessary, replace the servo amplifier and recheck the wiring.
Otherwise, it may cause smoke, fire, or an electric shock.
Provide an adequate protection to prevent unexpected restart after an instantaneous power failure.
After an earthquake or other natural disasters, ensure safety by checking the conditions of the
installation, mounting, wiring, and equipment before switching the power on to prevent an electric shock,
injury, or fire.
(6) Maintenance, inspection and parts replacement
CAUTION
Make sure that the emergency stop circuit operates properly such that an operation can be stopped
immediately and a power is shut off by the emergency stop switch.
It is recommended that the servo amplifier be replaced every 10 years when it is used in general
environment.
When using the servo amplifier that has not been energized for an extended period of time, contact your
local sales office.
(7) General instruction
To illustrate details, the equipment in the diagrams of this Instruction Manual may have been drawn
without covers and safety guards. When the equipment is operated, the covers and safety guards must
be installed as specified. Operation must be performed in accordance with this Instruction Manual.
