4 NOTES FOR SAFE OPERATION
E-9
„ OPERATION
„ DISPOSAL
• Perform trial operation while disconnected from the load.
Failure to observe this caution may result in product failure or injury.
• Do not stand within the machine’s range of motion during operation.
Failure to observe this caution may result in injury.
• Provide a stop mechanism on the machine such as limit switches, to ensure safety if the linear servomotor
malfunctions. Design the machine to ensure personal safety. The linear servomotor does not have a holding
or emergency brake.
Failure to observe this caution may result in injury.
• Do not come close to the machine immediately and touch the linear servomotor after resetting momentary
power loss to avoid an unexpected restart. Take appropriate measures to ensure safety against an unex-
pected restart.
Failure to observe this caution may result in injury.
• When an alarm occurs, remove the cause, reset the alarm after confirming safety, and then resume opera-
tion.
Failure to observe this caution may result in injury.
• If using the linear servomotor on a vetical axis, install a safety device such as a counterbalance so that the
workpiece does not fall if an alarm or overtravel occurs. Set the linear servomotor so that it will stop in the
zero clamp state at occurrence of overtravel.
The workpiece may fall during overtraveling.
• Do not touch the linear servomotor or machines connected to it while power is ON or soon after the power is
turened OFF.
Failure to observe this caution may result in burns due to high temperatures.
• Do not allow any metallic or other foreign matter to attach to the magnet track.
Foreign matter in the gap between the moving coil and the magnet track may result in equipment failure or burning.
• Heat the magnetic way for one hour at a minimum of 300 °C to degauss before disposal.
The force of the magnetic attraction may cause injuries.
• When disposing of the products, treat them as ordinary industrial waste.
