■ Wiring
Caution
Wiring connections must be secure.
Bodily injury could otherwise result.
Wiring should be completed based on the Wiring Diagram or the User Manual.
Electric shock or fire could otherwise result.
Wiring should follow electric equipment technical standards and indoor wiring
regulations.
An electrical short or fire could otherwise result.
Do not connect a commercial power supply to the U, V or W terminals of the servo
motor.
Fire or damage to the device could otherwise result.
Install a safety device such as a breaker to prevent external wiring short-circuits.
Fire could otherwise result.
Do not bind or band the power cable, input/output signal cable and/or encoder cable
together or pass through the same duct or conduit.
This action will cause faulty operation.
Must add the surge absorbing diode if inductive load as relay connect to the control
signal output of the amplifier. Please take care of polarity of the diode that will be
cause of failure.
Do not connect DC90V orAC power to the DC24V Brake of the servo motor. Also, do
not connect AC400V to the AC200V Fan of the servo motor.
An electrical short or fire could otherwise result.
Please design a sequence that included braking delay time because the
surge-absorbing component for the relay of holding brake of the servo motor gives
braking delay time.
Injury or load falling could otherwise result.
Mandatory
Install an external emergency stop circuit that can stop the device and cut off the power
instantaneously. Install an external protective circuit to the amplifier to cut off the power
from the main circuit in the case of an alarm.

Safety Precautions
vii
■ Operation
Caution
Do not perform extensive adjustments to the device as they may result in unstable
operation.

The holding brake is not to be used as a safety stop for the mechanism. Install a safety
stop device on the mechanism.
Bodily injury could otherwise result.
In the case of an alarm, first remove the cause of the alarm, and then verify safety. Next,
reset the alarm and restart the device.
Bodily injury could otherwise result.
Check that input power supply voltage is keeping a specification range.
Damage to the device could otherwise result.
Avoid getting close to the device, as a momentary power outage could cause it to
suddenly restart (although it is designed to be safe even in the case of a sudden restart).
Bodily injury could otherwise result.
Do not use motor or amplifier which is defective or failed and damaged by fire.
Injury or fire could otherwise result.
In the case of any irregular operation, stop the device immediately.
Electric shock, injury or fire could otherwise result.
When using the servo motor in vertical axis, provide safety devices to prevent falls
during the work that will cause an alarm condition.

Safety Precautions
viii
Prohibited
The built-in brake is intended to secure the motor; do not use it for regular control.
Damage to the brake could otherwise result.
Damage to the device could otherwise result.
Keep the motor’s encoder cables away from static electricity and high voltage.
Damage to the device could otherwise result.
Standard specification servo amplifiers have a dynamic brake resistor. Do not rotate the
motor continuously from the outside when the amplifier is not powered on, because the
dynamic brake resistor will heat up, and can be dangerous.
Fire or burn could otherwise result.
Absolutely do not apply voltage more than the spec to the amplifier because overvoltage
will be cause of part failure.
Damage to the device or bodily injury could otherwise result.
Avoid frequent on and off power supply.
Inner parts might get premature failure in case of repeating ON/OFF of power supply 30
times or more per day, otherwise 5 times or more per hour.
Mandatory
Install an external emergency stop circuit that can stop the device and cut off the power
instantaneously. Install an external protective circuit to the amplifier to cut off the power
from the main circuit in the case of an alarm.
Motor runaway, bodily injury, burnout, fire and secondary damages could otherwise
result.
There is no safeguard on the motor. Use an over-voltage safeguard, short-circuit
breaker, overheating safeguard, and emergency stop to ensure safe operation.
Injury or fire could otherwise result.
Operate within the specified temperature and humidity range.
Servo Amplifier
Temperature 0°C to 55°C
Humidity below 90% RH (non-condensing).
Servo Motor
Temperature 0°C to 40°C
Humidity below 90% RH (non-condensing).}
Burnout or damage to the device could otherwise result.

Safety Precautions
ix
■ Maintenance・Inspection
Caution
Some parts of the servo amplifier (electrolytic capacitor, cooling fan, lithium battery
for encoder, fuse and relay kinds) can deteriorate with long-term use. Please
contact our offices for replacements.
Damage to the device could otherwise result.
Do not touch or get close to the terminal while the device is powered up.
Electric shock could otherwise result.
Be careful during maintenance and inspection, as the body of the amplifier
becomes hot.
Burn could otherwise result.
Please contact your distributor or sales office if repairs are necessary.
Disassembly could render the device inoperative.
Damage to the device could otherwise result.
Prohibited
Do not overhaul the device.
Fire or electric shock could otherwise result.
Do not measure the insulation resistance and the pressure resistance.
