Installation and Wiring
Operations
Do not directly touch the terminal portion of any connectors.
Do not block the air vents. Do not allow ingress of any foreign objects to
the product.
Keep the motor-amplier pairing as specied.
Before a test run, conrm that the motor is xed in place, check the motions
while the motor is isolated from the machinery rst, then install the motor in
the machinery.
Observe the mounting method and orientation as specied.
Install the product in an appropriate way suitable for its main body mass
and the rated output of the product.
Do not step on the product or place any heavy object on it.
Never make drastic changes during tuning, which if not observed, will
result in unstable motions.
Do not come close to the machinery right after power restoration
following a power outage. The machinery may restart unexpectedly at
any moment. Take appropriate measures to ensure safety against an
unexpected restart.
Do not use the product where it may be exposed to direct sunlight.
Do not apply impact load.
Never use the electromagnetic contactor installed on the main power
supply-side to operate or stop the motor.
Do not use the built-in brake of the motor for regular braking purposes.
It is a holding brake.
Do not use faulty, damaged motors or amplies.
Conrm that the power specications are normal.
The holding brake is not a stopping device to secure the safety of the machine.
The machine requires a separate stopping device to secure safety.
Upon occurrence of an alarm, remove the cause and ensure the safe
condition of the equipment before resetting the alarm and restarting the
machine.
Connect the brake control relay and the emergency stop relay in series.
