„ Operation
• Install external breakers or other safety devices against short-circuiting in external wiring.
Failure to observe this caution may result in fire.
• Take appropriate and sufficient countermeasures for each when installing systems in the following
locations.
• Locations subject to static electricity or other forms of noise.
• Locations subject to strong electromagnetic fields and magnetic fields.
• Locations subject to possible exposure to radioactivity.
• Locations close to power supplies including power supply lines.
Failure to observe this caution may result in damage to the product.
CAUTION
• Do not stand within the machine's range of motion during operation.
Failure to observe this caution may result in injury.
• Before operation, install a limit switch or stopper on the end of the slider to prevent unexpected movement.
Failure to observe this caution may result in injury.
• Before starting operation with a machine connected, change the settings to match the parameters of the
machine.
Starting operation without matching the proper settings may cause the machine to run out of control or malfunction.
• Forward run prohibited (P-OT) and reverse run prohibited (N-OT) signals are not effective during zero point
search mode using parameter Fn003.
• If using the linear servomotor on a vertical 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.
• When not using the online autotuning, set to the correct mass ratio.
Setting to an incorrect moment of inertia ratio may cause vibration.
• Do not touch the SERVOPACK heatsinks, regenerative resistor, or servomotor while power is ON or soon
after the power is turned OFF.
Failure to observe this caution may result in burns due to high temperatures.
• Do not make any extreme adjustments or setting changes of parameters.
Failure to observe this caution may result in injury due to unstable operation.
• When an alarm occurs, remove the cause, reset the alarm after confirming safety, and then resume
operation.
Failure to observe this caution may result in injury.
