CAUTION

Provide an external emergency stop circuit to ensure that operation can be stopped and power switched off immediately.

Any person who is involved in disassembly and repair should be fully competent to do the work.

Before resetting an alarm, make sure that the run signal is off to prevent an accident. A sudden restart is made if an alarm is reset with the run signal on.

Do not modify the equipment.

Use a noise filter, etc. to minimize the influence of electromagnetic interference, which may be caused by electronic equipment used near the servo amplifier.

Use the servo amplifier with the specified servo motor.

The electromagnetic brake on the servo motor is designed to hold the motor shaft and should not be used for ordinary braking.

For such reasons as service life and mechanical structure (e.g. where a ballscrew and the servo motor are coupled via a timing belt), the electromagnetic brake may not hold the motor shaft. To ensure safety, install a stopper on the machine side.

(5) Corrective actions

CAUTION

When it is assumed that a hazardous condition may take place at the occur due to a power failure or a product fault, use a servo motor with electromagnetic brake or an external brake mechanism for the purpose of prevention.

Configure the electromagnetic brake circuit so that it is activated not only by the servo amplifier signals but also by an external forced stop (EMG).

When any alarm has occurred, eliminate its cause, ensure safety, and deactivate the alarm before restarting operation.

When power is restored after an instantaneous power failure, keep away from the machine because the machine may be restarted suddenly (design the machine so that it is secured against hazard if restarted).
