Introduction

 Usage Precautions
Caution

Install an emergency cut-off switch which immediately stops operation in an
emergency.
 Reset the alarm when the servo is off. Be warned that the system restarts
immediately if the alarm is reset while the servo is on.
 Use a noise filter or DC reactor to minimize electromagnetic interference. This
prevents nearby electrical devices from malfunctioning due to interference.
 Only use approved servo drive and servo motor combinations.
 The electric brake on the servo motor stops operation. Do not use it for ordinary
braking.

The electric brake may malfunction if the brake degrades or if the mechanical
structure is improper (for example, if the ball screw and servo motor are combined via
the timing belt). Install an emergency stop device to ensure mechanical safety.
 Malfunction Precautions
Caution
 Install a servo motor with an electric brake or separate the brake system for use
during emergencies or device malfunctions.
 If an alarm occurs, solve the underlying cause of the problem. After solving the
problem and ensuring safe operation, deactivate the alarm and resume operation.
 Do not approach the machine until the problem is solved.
 Repair/Inspection Precautions
Caution
 Before performing servicing tasks, turn off the power. Wait 15 minutes until the charge
lamp goes off, and then check the voltage. Enough voltage may remain in the
condenser after the power is off to cause an electric shock.
 Only authorized personnel may repair and inspect the device or replace its parts.
