1. Safety Precautions
(Operation)
20. The motor is not equipped with protection means. Install an earth leakage breaker, an
excessive temperature rise prevention means and an emergency stop unit as necessary
protection measures.
Failure to do so may result in an injury or a fire accident.
21. Never touch the heat sink of the amplifier, regenerative resistor, motor, or other part
while the power is on or for awhile after the power has been turned off.
These parts may become very hot, causing a burn on contact.
22. In the event of any abnormality, stop operating the system at once.
Failure to do so may result in electric shock, injury, or fire.
23. Never make an extreme adjustment change that will cause the system operation to
become unstable. Doing so may result in injury.
24. At trial operation, fix the motor and check the operation separate from the mechanical
system, then install the system on the machine. Failure to do so may result in an
injury.
25. The holding brake is not a stop unit to secure the safety of the machine. Install a stop
unit to secure the safety on the machine side.
Failure to do so may result in an injury.
26. When an alarm occurs, remove the cause of the alarm and secure safety. After that,
reset the alarm, then result the system operation. Failure to follow this procedure may
result in an injury.
27. After a recovery from an instantaneous power interruption, the operation may be
restarted suddenly. Do not approach the machine. (Design the machine so that safety
for personnel may be secured even if the system operation is restarted.)
Approaching the machine when it restarts may result in an injury.
28. Make sure the supply voltage is within the specified range. If the supply voltage is out
of specification, functional failures may occur
