„ Operation
• Take appropriate measures to ensure that the input power supply is supplied within the
specified voltage fluctuation range. Be particularly careful in places where the power supply
is unstable.
An incorrect power supply may result in damage to the product.
• 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 fol-
lowing locations.
Failure to observe this caution may result in damage to the product.
• 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.
• Do not reverse the polarity of the battery when wiring with regenerative unit.
Failure to observe this caution may result in damage to the product.
• 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 using a servomotor with a holding brake, run a trial operation to confirm that the hold-
ing brake activates correctly. Also, take appropriate measures to ensure safety against an
error such as signal line disconnection.
• Before starting any operation with a machine connected, change the settings of the SERVO-
PACK’s reference pulse with the PULSE rotary switch to match those of the machine.
Starting operation without matching the proper settings may cause the machine to run out of control
or malfunction.
• When using the servomotor for a vertical axis, install safety devices to prevent workpieces
from falling off because of alarms.
Workpiece’s falling off may result in injury or malfunction.
• Do not touch the SERVOPACK heatsinks, regenerative unit, 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.
• When an alarm occurs, remove the cause, turn OFF the power and ON again after confirm-
ing safety, and then resume operation.
Failure to observe this caution may result in injury.
• Do not use the holding brake of the servomotor for ordinary braking.
Failure to observe this caution may result in malfunction.
