1. Before Use

1. Important Safety Instructions

CAUTION

Installation and Wiring

Operations

Do not directly touch the terminal

parts of any connectors

Do not block the air vents� Do not allow ingress of any foreign objects to

the product�

Keep the motor-

drive

pairing as specified�

Before a test run, confirm that the motor is fixed in place, check the motion

while the motor is isolated from the machinery first, then install the motor in

the machinery�

Observe the mounting method and orientation as specified�

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 motion�

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

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�

Confirm that the power

supplies

are

within specification

�

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�

Sign

Precautionary Measures

If Not Observed

Do not use faulty, damaged motors or drives
