• Conduct trial operation on the servomotor alone with the motor shaft disconnected from machine to avoid
any unexpected accidents.
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.
• When using the servomotor for a vertical axis, install the safety devices to prevent workpieces to fall off due
to occurrence of alarm or overtravel. Set the servomotor so that it will stop in the zero clamp state at
occurrence of overtravel.
Failure to observe this caution may cause workpieces to fall off due to overtravel.
• When not using the normal autotuning, set to the correct moment of inertia ratio.
Setting to an incorrect moment of inertia ratio may cause vibration.
• Do not touch the SERVOPACK heatsinks 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.
• Do not use the servo brake of the servomotor for ordinary braking.
Failure to observe this caution may result in malfunction.
• When replacing the SERVOPACK, transfer the previous SERVOPACK parameters to the new
SERVOPACK before resuming operation.
Failure to observe this caution may result in damage to the product.
• Do not attempt to change wiring while the power is ON.
Failure to observe this caution may result in electric shock or injury.
• Do not disassemble the servomotor.
Failure to observe this caution may result in electric shock or injury.
• When disposing of the products, treat them as ordinary industrial waste.
