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.
