CAUTION
1. To prevent unstable or erratic operation never make drastic adjustments to
the unit. Doing so may cause injury.
2. Install a safety circuit that actuates an electromagnetic contactor to cut off
the main circuit power supply in case of an alarm.
3. If an alarm has occurred, eliminate the cause of the alarm and ensure
safety. Then reset the alarm and restart the operation.
Failure to do so may cause injury.
4. If a momentary power outage occurs and power is restored, the unit might
suddenly restart so do not approach the machine at that time. (Design the
machine so that personal safety is ensured even if it suddenly restarts.)
Failure to do so may cause injury.
5. Make sure that the AC power specifi cations match the product power
specifi cations.
Using the wrong power specifi cations may cause injury.
6. While power is being supplied, do not touch any parts inside the robot driver
or its terminals.
Also, do not check the signals or attach/detach the cables.
Doing so may cause electrical shock or injury.
7. While power is being supplied, do not touch any terminals on the robot
driver even if the robot is stopped.
Doing so may cause electrical shock or fi re.
8. This product does not incorporate any power failure detection function.
When necessary, install an external power failure detection circuit and
confi gure an appropriate circuit that stops the operation safely when a
power failure is detected. (Refer to 4.3, "Emergency stop", in this chapter.)
MANDATORY
